Meteorologic, surface water and groundwater records for éach of the three major U.S Virgin Islands - St. Thomas, St. . ‘John, and St. Croix are inventoried. The location of each data leollection point is given as well as other characteristics such '-las altitude, and length of available record for that station. For each island, summaries of the available data are made and infor- mation.given to facilitate locating published data. Precipitation records, hitherto unpublished, collected by private individuals . are included for each island as made available tous by the _ private collectors. No attempt has been made to revise any: of the . jdata. -It is hoped that these data will assist the efforts of water resources planners, researchers and managers in the Virgin Islands. : Ss - AKNOWLEDGEMENTS _. We are grateful to ‘local and. federal government *_ agencies ‘in’ the Virgin Islands and.Puerto Rico that assisted us in this effort by answering our. requests . for assistance and opening their files and records to us and allowing us to.use their facilities in copying data... ‘The encouragement received by their enthusiasm, support and suggestions | contributed significan~ tly to our efforts. We are especially thankful also to the several | private citizens who through the years have on their own |initiative maintained weather records and who have unselfishly |lprovided these to us. The contribution of. each observer is acknowledged appropriately in the text. - In the processing: ‘of the. mass of data which formed: {the bulk of this report, we are ‘especially. grateful to our ~ research assistants; Mr. Clement Browne and Mr. Philmore Andrew, ° ‘|both students at the College of the Virgin: Islands. We are also .|grateful to Mr. Robert Waters of the College’ s Physical Plant '{Department for his assistance in- reviewing this. report prior to .|publication.- Efforts were made to contact all persons whom we |feel may be in a position to supply us with previously . |unpublished data to be included in the compendium. However, it is “'/possible that there are unpublished | data somewhere out there. We [hope to be able. to include ‘these in future annual updates or :| Supplements to this compendium. The task of data collection for [water resources assessment is a continuous process in any case. : ‘We also hope. that we. have: minimized errors in the | . data. presented here, but will. appreciate such being brought | ‘to our . attention. . : jLII. live. -IVI.e-: II... - PART ONE - PART TWO VII. .

States located in the Caribbean Sea, [approximately 1,166 Iniles east-southeast of Miami, Florida and. |500 miles northeast of Caracas, Venezuela, Figure l. (1) - The U.S. [Virgin Islands .consists of three large islands ana ‘more than forty small, islands and cays. The three largest inhabited listanas; ‘st. “John, St.. Thomas, and St. Croix, have respective land areas ‘of approximately 19, 32, and 84 square’ miles. All islands are characterized by steep rocky mountains of voleanic origin. The islands also display diverse ecological systems . ranging: from: beaches and: ary thorn scrub of the lowlands to the > -|aeciduous forests of the higher elevations. (2) ~~ Iwature of water resources data ‘there is: no amount ‘of: simulation which can substitute ‘| €or - historical. data: The Office of Water Data. Coordination of — the. united States. Geological survey: (uses) has published parts of | vao manual entitled “National Handbook of Recommended Methods for | Water Data Acquisition" which in the final form will consist of. an “introduction, . 12 technical ‘chapters, and an appendix. | The . “| following chapters | are to be “ineiuaea.(3)_ . 1) Surface water; .2) > “Ground Water; 3) Sediment; : 4) Biologic and Microbiologic: Quality of Surface and.

Characteristics; 8) Evaporation and Transpiration; 9) ‘Snow and Ice; 18) Hydrometeorological Observations; 11) Water Use;. and 12) Water data Handling and Exchange; The above chapters represent a comprehensive list. of | areas for. which data must be collected for a complete. quantita~ - || tive and qualitative assessment of the water resources of a a region. The sampling requirements in each of this areas is. conditioned by the nature of the investigations. “However, “for. “|most parameters, a fairly, continuous and extensive data base is necessary | in order to: fully characterize ‘the phenomenom of ' /interest. ‘Tt is obvious - to nearly everyone, that there. is a need for long-term precipitation, temperature and other records in’ Jorder: to full Characterize the climate. of. an area. The. need _for:.. long-term water level records in order to. Characterize ‘the . groundwater regime of an-area isnot’ so obvious. “Furthermore” ; transient’ changes in water quality ean only be determined as a result. of systematic. monitoring of the indices of water quality” . - lover time. These ‘measurements, : taken over a wide area, require, [stanaara equipment and methods of analysis | and. interpretation in: _jorder to be ‘strictly comparable over the. given area. — Stringent : controls: also need to exercised on the quality of personnel - pollecting the data. . Need .for water Resources Data in the Virgin Islands ‘Water. resources data provide « a! scientific basis. for” water: planning and management. Rainfall, runof£, evaporation ana ‘groundwater level data are required to quantify the potential and | petiial freshwater resources of the Virgin’ Islands. Quality of water data are also required for a complete water resources assessment. - ' | Proper planning and. management. is necessary for “the best utilization of water resources. Intrinsic in all water “resources planning. and management efforts is the need for ‘pasic. water resources data. The planner anda manager must have some idea - bf the quantity and quality of water available from. each source, ses to which the water will be put, as well as the expected, oe . Hemand for water. It is:also required that the spatial as well ps ‘the. temporal distribution of both the water’ available and’ the _water needed be ‘known since the: goal of water resources s manage- nent is how the. availability of water can best | be structured to:- feet. demand. oo The lack of basic water resources data has been one of | the hindrances to proper. water resources planning and management -an the Virgin Islands. Very little: has been done localiy to. _bystematically collect water resources, data.(4) Water resources @ata here, for the most “part have been ‘kept in a very informal “Wanner by. individuals as a hobby, or by groups based primarily outside the. ‘islands such as “the -U. s Geological Survey; the a National Weather Service and the Federal Aviation Administration. ‘Pecasional | student groups from the. mainland have also collected data. on an informal basis. other ‘crucial water resources data puch. as: sediment transport, ‘evaporation, soil water inovement aind storage in the unsaturated zone chave essentially been neglected © as far as long. term record keeping is concerned. '. There is “also a need for the compilation of the water ‘|resources data that is available and scattered: in’ disparate sources. Presently, researchers and ‘planners in water resources, ° in the virgin Islands must look into several sources, not readily | _pvailable,, for pertinent data. Furthermore, there. is no annual ‘compilation of water resources data in one source ‘for instant reference, ‘There is a vital need. for readily available clima- — tological and water records of the Virgin Islands for , researchers, planners and water managers in the Territory. | With the’ exception of data on snow ana ice, collection of most of the water data re ferred to-in 1 the National Handbook | wil greatly. aia the water management efforts of the ‘virgin ‘jtstands.. Most states have > agencies charged with water resources |data collection. Water use data is also: an. important component of © {a general water resources assessment for an area. There is a vital. need. for an agency of. the Virgin Islands government to .jcollect: and compile water data ‘for. the: virgin Islands ona perma~, nent ‘basis. " jorganization of this. report | ) A general evaluation is made of. ‘the water resources -ldata which should be collected to. aid water ‘and land management “lefforts | in the Virgin Islands. The ‘history of. water data collect= ‘lion in the. Territory’ is presented, followed by a | description of the existing water. data collection network. ‘comments are made on _jthe- reliability of water data collected in ‘the virgin Islands. An assessment will be made of the water resources data that is available for each of the three major islands ‘of St. ‘John, ‘ist. Thomas and St. Croix. This: "assessment will include tables | | summarizing the location of each data collection site, the type of. data collected ‘there and the history of water data collection. As an aid ‘for, quick reference, ‘maps ‘have ‘been: included in the appendices Of this report. showing the ‘location of most | of the data “|eollection sites. It is ‘recommended ‘though’ that users .of this. jcompendium use the latitudes and logitudes provided in the summary jtables for determination of the approximate location of the sites. Where the data has been previously published and is readily -javailable, appropriate references will be given. ALL previously _ unpublished data, or data not readily available will be. ‘reproduced ; as part of this report. In general, data collected for a duration _ . of. less: than: one year will ‘not. be included in this report. |II. ° WATER RESOURCES DATA COLLECTION “IN ‘THE U.S. VIRGIN ISLANDS. | History of Water Data Collection. There ‘is no local government agency in. the Virgin Islands. which. has collected or compiled water resources data on a sustained basis since the islands. became a U-S.. possession in 1917. The majority of the data. which has been collected to. date, “awith. few exceptions, are scattered and for the most part not readily accessible. The history of weather observations in the Virgin: ‘Islands.is rather interesting. Excellent ‘data were compiled. during the Danish regime, from about 1825. on....Some official Danish stations were still repor— _ ting in 1917, but thereafter the United States .Government. gave no special ‘attention or encouragement _to these or other xr weather observers, ‘except. at Charlotte Amalie and Christiansted, until. the US Weather Bureau began to establish more ‘cooperating ‘stations’ in .1926. (emphasis | added) - This lack of: of ficial blessing for water ‘data ‘collection efforts ‘|. by the. federal ‘government: is also reflected by the local. govern- ment which apparently has not shown: interest in water data | | contection; since no local agency is” presently engaged in this ‘task: Consequently, most records. collected: ‘by private individuals. “are, toot without ever being published or analyzed. "stone (6) gives an excellent. history of the meteorological records of the Virgin Islands collected prior to -| the U. S. purchase of the islands in 1917. Appendix Table 1 in | Stonel6). gives a summary of recording stations and available records from the earliest. records to the date of publication, 1942. Over the years, rainfall is the only, parameter which vhas been’ systemati¢ally collected, and records of rainfall are ‘generally of "long duration. Other climatological and pyaron logical. parameters such» as - evaporation; groundwater levels and. Le water quality data are collected for specific ‘studies, for short - lperiods of ‘time only, and subsequently discontinued. The absence . of sustained records for all parameters of the hydrologic cycle , does. not allow water balance ‘to ‘be calculated for various water- / sheds - cin: the Virgin Islands. Existing data collection network There are very few sources of original : water resources laata for the U.S. Virgin. Islands. “The National Weather Service _ jana t the U. Ss. Geological Survey are the: prime sources. of water resources data collection on a systematic basis. The U.S. _|eeotogicar Survey. operates stream gaging and groundwater level monitoring | network, none of which is permanent, but: changes as . the heeds: and. available funds: dictate. The most intensive data ; a |coutection effort of the uses was between 1962 - 1969, (7) Oo The National Weather ‘Service does not maintain: a | net-" work. Of observation stations as such. It relies * ‘on a. system of volunteers: as’ observers to report. rainfall ato so-called 7 ‘official’ stations. | o The population of ‘the islands includes a substantial | - amount of weather conscious, semi-retirees | from the U.S mainland, some of whom have been privately engaged in the collection: of rainfall data on the islands for upwards: of fifteen years. Some lof these privately collected records» are, ‘published for the first. "Ieime in ‘this compendium. There is a need for official ‘sanction and encouragement for these observers. Also, their records: néed 7 “ito be. compiled: periodically and made available for ¢ water planners and researchers: _ The local government of the Virgin Islands does not ‘Wnaintain < any official network for collecting water resources ata. However, at various times in the past, it has financed ‘ tinvestigations by the Caribbean District Of the USGS based’ in San Juan, Puerto Rico. This cooperative effort has been for short : periods of time. only. The last major systematic and continuous effort extending over a long périod of time was carried out _ between 1962 and 1969 when surface water, quantity | ‘and quality bf water, and groundwater . data for all: the islands were’ collected “by: the ‘usés in cooperation with the, National Park Service, and “ithe government of the Virgin Islands. | } , currently, the Caribbean District of ‘the usGs ‘based in ~ San Juan maintains. a few observation stations on each of the = three islands. The parameters being measured include surface water and groundwater levels. The present coverage - is “not. ade~ / ‘quate to ) provide the basis for a realistic assessment of ‘the Water’ resources of ‘the Virgin Islands. | | The National Weather Service maintains a system of “keporting stations on the islands. The ‘chief parameter being _ ‘beportea is 24-hourly rainfall totals. While the absolute density pf. observation stations. appears to be satisfactory for small islands. of this size, the areal distribution of reporting sta’ ‘buons: leave relatively large areas, including several important” ; , watersheds. on each island inadequately covered.” Given ‘the wide variations ; in. ‘rainfall distribution due to orographic effects on the islands, a better areal distribution of reporting gages is lessential fora realistic determination of the ‘areal distribution and the incidence of rainfall throughout the islands. Reliability of. Water Data “Collected _ The method by which water data is collected in the Virgin Islands does. not ‘contribute much to reliability of data. - Most of the observers are volunteers who do not have prior , training or ‘certification for the job. | These data are not strictly comparable with | one another because of a lack of stan- dardization in either the Gata collection methods ana or + equip- ment. especially for. the ‘private | hobbyists: collecting water data. 7 some degree. of standardization. in equipment | will help. to overcome some = of this. problem among the hobbyists. | | - . The quality of the data collected can be improved by - having training sessions for observers as a group or “individually: in their homes. The data collected | Can be made comparable over a- given ‘area by supplying the observers with’ standard equipment: at government expense. | ‘Most of these observers have. been collecting. ‘fdata for upwards: of ‘fifteen years ‘on their own » initiative. ‘They ‘|neea’ to be better encouraged and supported as’ ~ they provide a ‘|valuable service for users of: water data. .

IN TABLES . ‘|General Remarks Several takles are “included in this, report and:-a brief description of the “outline of each table is presented here to aid “the general reader. At the beginning of the. chapter devoted to each island is a table summarizing the available water resources - data in three parts; meteorological, surface water anda ground- water: ‘These tables are. followed by monthly summaries of data for “| each | station for the parameter. of interest for all the record ‘years. Daily measurements round up # the tables for previously unpublished records. | | The remarks after each table includes references to _ | sources of data and in some instances contain comments on. data | |soltection methods or peculiaritiés of the collection site. The ‘reader is also alerted to. possible sources of excors | in the data, . here. There. has been no attempts made to revise ‘the data or | otherwise substitute for missing data.. Monthly totals are omitted for. months having missing daily data. Similarly, annual totals |are omitted for years with missing monthly data. This compendium ) |includes all data up to December, 1982. 16 Abbreviations and Symbols The tables contain few: abbreviations and symbols not - : explained | ‘in the remarks. The’ following | are “used widely ‘through- “« ~- {out the ‘tables. | 2 A. The symbol, A, following a station name stands for "an active station at the end.of. December, 1982, _ the terminal date of data included in this report. . In general, stations having records up to 1982 can be presumed to be currently. active as of Januarys 1983. i P- ‘whe. symbol, P, following a year indicates. partial records were collected during that year. N This symbol Genotes that the. record is not. available. Y This symbol ~ denotes the availability of the appropriate _, record... ne This symbol denotes missing: data. In some rainfall So ‘totals, the ‘missing values: are included in the : total for the next day. For example,. rainfall during two days might be read cummulatively on the second day, while the rainfall value for the | previous day might ‘be indicated as ‘“missing.' ll PART ONE: WATER RESOURCES DATA of ‘ST. JOHN, st. John. is the smallest of the ‘three “major U.S. (Virgin. ‘| Islands with an area of 19 square miles. “Mountains: dominate the : topography of this sparsely populated island, approximately seventy - percent of which is controlled by the U. Ss. National - Park Service. — A ridge runs eastward through the island. sloping steep-. ly. to: the sea on the northern side, while. on, the: southern side’... |serveral prominent spur ridges extend from it. The highest point along this main ridge is Mamey Peak with an altitude of 1,197 7 ||£eet. Forming on these spur ridges is Bordeaux Mountain with an ‘altitude of 1,277 feet, the island‘s highest point. The eastern jena of the island is principally a long irregular peninsular: extending southeastward about 3 miles from the main ridge. . .As would be expected there are no large drainage’ basins | on: St.John. The largest are. the watersheds of the Reef. Bay Gut [and Fish Bay Gut. with areas. of. 1.78. and 1. 10 square “miles jrespectively,. followed by 7 the watershed of Coral Bay.

THOMAS. St. Thomas with an area. of 32 sauare nites is the second largest. of the three major islands: of the U.S. virgin ‘Islands. The island is approximately 19 miles long. and 2 ‘to 3. miles wide. Flat land is ‘generally rare on St. Thomas for most of the land surface is sloping and. extends seaward from a central ridge, 800 to. i, 200 feet high that runs almost the entire length of the ‘island. The flat areas are found. for the most part in: | Charlotte Amalie, the seat of government of the Virgin Islands, and a few alluvial-filleda embayments. These embayments: are sel- dom less thana few acres with the thickness of the alluvial | deposits at. a maximum peing generally less than 58 feet. “In addition to rain water harvesting, “groundwater is the only other significant "natural" water source on ‘St. Thomas. Surface water supplies are negligible. .AS-a result of the topog- . Yaphy none of the streams in St. Thomas are ‘truly perennial. bonne Resolution Gut and Turpentine Run in the north and’ eastern ‘parts of the ‘island, although often described as perenial, have been known to go dry during extreme drought periods. It has “been estimated that in the perennial reaches of these streams - about one-half to three-fourths of the flow. is storm runoff and the remainder is. base flow contributed by groundwater.(9) "Groundwater, though not abundant, is mined ‘throughout the’ island in varying amounts. In St. Thomas groundwater move- ‘ment is limitea mostly to Openings along joints: and fault zones. The ma jor portion of the ‘island: is underlain principally by fractured volcanic tuff ana breccia of what is called the ‘Louise-_ - 52 nhoj Formation.” “Soil to a. “depth of 1 to 2 feet” have ‘developed : in this formation. While. ‘the » underlying bedrock, especially in ‘the . ‘flat areas, has been tapped and can be a reliable source of water, extreme care must be exercised due to ever present danger of salt water intrusion if over pumping occurs.) Sources of Data A: Meteorological. | The National Weather Service is the repository of almost all available for St. Thomas. Of the. several private collectors of rainfall data on St. Thomas, Mr. Patrick M.. Rice of Estate Solberg has perhaps the longest récord, . These records extend from. October 1978: to December 1982 and are. - reproduced in this compendium. The rainfall records collected at “the College of the Virgin Islands from 1979. to’ the present 3 in the . form of charts have’ yet to be translated and have not been in- ; eluded here. The rainfall record from the non-recor@ing gage "” ; during 1982 was far less ‘than one year and is also not included. — Bi: ‘Surface Water. The Caribbean District of the United ~ States “Geological survey (USGS) is the only agency collecting surface water records on St. Thomas. These’ are summarized in the. accompanying tables, Cc: Groundwater. ‘The USGS likewise is ‘the ‘sole source of - groundwater level records on St. Thomas.. A summary . of available data is given in the tables. Addition information on wells ‘in St. Thomas can be found in References 6 and 7. 53 QOST-6S6T dgg6t AS6T vS gle — G9 eT ZB6T-SSET ZS6T-TZET QLET-SSET ZS6T~PEET 9¢ ZZ6T ST 95559 T28T STTRUNY SIVOTIRU) ALZet 9ZeT-GZ6T dyzet €C6T-TC6T €Z6T dézet 069 65009 T28t couertedsy Suucg LT Le6eT-Tzet yearzay s ,cuuy _ Teton SUVA SWaA CEOORR NOLIWLTd Tom ‘Talon SaWaA Sawada CHICO (3283) ’ (RU) VaR CEOIVENCNL ACL LUTZ HCOLIANST SOOLLLVT CHnseara NOLIMLS TWOIDOICHOMINN * W SWOHL “15 Ui WI SONOS UAT FVIWY 2 AMIS See dBL6T i LL6T-SOST QT.

PART THREE: WATER RESOURCES DATA OF ST. CROIX With: an aréa of 89 square miles, St. Croix is the. largest. island of the U.S. Virgin islands. The topography on A Ste croix is in general more subdued than’ ‘the topography. of: St. Thomas and St. John. ‘The highest point on the islana is. the uo peak at. Blue Mountain, an’ elevation of 1,096 feet above ‘sea. ‘level. | | | The northside range on St. Croix is the origin of the /£our most important streams on the island. These streams have intermittent reaches but are significant | because all other streams. on the island are ephemeral. Storm runoff throughout. the “island | is surprisingly low and is attributed to the capability of the soil zone to. accept large volumes of water. The water re- . tained in the ‘soil zone is ‘depleted primarily. by evaporation and ‘transpiration by plants so - that: the water available. for recharge — . is very. small. | | "There are three’ major groundwater provinces inst; | Croix. These correspond generally to the geological framework: of the island. In ‘the northwestern and eastern portions: of ‘the “island is. found the ‘Mount Eagle Group of epiclastic. and pyroclas- tic. volcanic and. associated intrusive. rocks. The “principal " waterbearing zone in these rocks | ‘can be visualized as a ‘mantle ‘266 | to 308° feet thick following ‘the general topographic relies. These xocks have low permeability, therefore. ‘the water table has a high: relief and. stands hundreds of feet above sea level in. the ‘| mountains and.slope steeply towards the valley and coastal 64 lowlands. Groundwater funnels through ‘the valley to discharge to. | - the. sea, other water-bearing rocks or to: streams. ) In the central and southwestern portions of the isiana; groundwater is generally found in the Kingshill Marl which is” . composed of calcareous rocks - limestone, sandstone. and marl. “This marl is soft and. plastic with tight joints. There: are infre- “quent permeable zones which are generally localized. in beds of | Limestone, sand. or gravel. Where limestone beds are present "permeability is greatest and: well yields are relatively high. "Sources of Data | A: Meteorological. The National. Weather service is the “repository of almost all. available meteorological data for St. |, Croix. There are several individuals who maintain rainfall “records privatey. Mr. John Yntema is ‘one of these. He has kept “vainfall records: at his home at Sprat_ Hole, St. Croix since “1961... Mr. ‘Yntema's ‘records are published: here. -B: Surface water. The Caribbean ‘District of the united - States geological Survey (uses) is ‘the only agency collecting , purface water records on St. Croix. These are summarized in the | accompanying ‘tables. ‘¢ 3 Groundwater. The USGS is the only ageiicy” colleéting / groundwater ‘level data in the Virgin. Islands, There is ‘no. local. agency of the Virgin Is lands. goverriment engaged in collecting ox | analyzing groundwater level records in the islands, even though | | the Virgin Islands coae(®) makes adequate provisions for ‘access to wells for the _ purpose of measuring water level. records. 65 a SIPNARY CF AVAILABLE FNOFCLOGICAL DRA FOR ST CROIX A: METEOROLOGICAL STATION LANE LONGITUDE» ALTITUDE PRECIPITATION WATERSHED AREA (feet) (mi.“) RECORD YEARS YEARS TOTAL 10.46 17°43 64°48 146 1944-1946 1947-1948P 1956-1965 1966P 16 Alexander Hamil- 3.92 17°42 6448 18 1948 1947P ton Airport 1951P 1948 1952 1952p 1955P 1949-1952 1956-1961 1955-1961 1962P 1962P 1963-1968 1963-1982 1969P 1978-1973 1974-1975P 1977P 1978-1980 1981P 29 Anguilla 17°42 64°47 75 1938-1939 1949 66 ‘LO 8g: ee 7B6T-SSET . cS6T QS6T CGP6T-BPET Lb6T-OP6T : dGv6T—Ph6T vet - — ahet TH6T dQpet BGT TROT LT QLET-696T G96T-LO6T GO6T-EGET as6T LS6T “aQG6T-SSeT — , a@S6T-TS6T 7 aRS6T=TSET. “pet a io” ae SEB T-BEGT .C86 T-8S6T — dLS6T OvET ' avE6T oo SBT ZEST PEST-626T oo, ee ABET, Tp | GolT Ob - “ROL : SGA GOO SANGER SaWwan ‘SRINTIAWAL SOOLLETY .

In addition, previously ; - uripublished data have been assembled in this report: for. ‘the first time. ~The. user of these data is hereby warned against uncritical use because there is no standardization of equipment or methods. ‘between the official. cooperating stations and the private beer ivers. ‘In fact, there is’ no strict comparability. of rainfall. data. among the. private observers for ‘their instruments. vary. ‘The. data ‘has been assembled on the’ premise that ‘some. data : vis. better. than no a data at all in the. task of water resources assessment. It is: possible. to. “standardize” non-standard data by statistical ‘techniques. and procedures. Such. a task is ‘beyond. the scope of the _ Present _ exercise. In spite the Mass of data assembled in this report and— “refered to. in the bibliography, - .we feel that. there is a critical | “deficiency: in | the water resources ‘data base. available for the Virgin Islands. ‘There isnot enough water level. measurements or | quality of water investigations being conducted. Soil moisture, evapora— tion and other parameters which will aid ‘in. assessing ‘the -poten- tial needs for irrigatea agriculture, are largely neglected. it is. 194. _. impossible to devise decision rules for agricultural, water needs” or. domestic water supply..from rainfall and groundwater sources in. the: absence of essential water data. - — In view. of the foregoing, it is highly récommended that an _ agency of the Virgin Islands government be charged with the” "responsibility for collecting, analyzing and timely publica- . . tion of water resources data to aid | water management efforts. ‘The government should: also encourage “and assist the - private indivi- duals: who have: been collecting rainfall data, some for upwards of '£ifteen years. One way to ensure strict comparability of data would be to provide all volunteers with standard equipment. ‘Further research into the various water needs of the terri- ‘tory ; is ‘necessary in’ order to devise an appropriate water data, collection effort. In the absence of actual data on water : “resources. of the territories, systematically collected over a "long period of time, the. worth’ of any water resources assésment’ or. management plan. for the islands water resources is. s questionable. Consequently it is recommended that greater efforts be directed towards the collection and dissemination of basic water ; resources data such as rainfall, evaporation, water level measurements and quality of water determinations for use by the islands' water planners, reséarchers and ‘managers. ‘Towards this ena, it is: “recommended that supplements and annual updates to this compendium be regularly published by a government agency ‘of the Virgin Islands. The supplements will fill the gap in. existing, knowledge while annual updates will summarize water resources data since the previous year of publication. 185 |...
