Water resources of the Nooksack River Basin and certain adjacent streams
Water Supply Bulletin 12 (1960) describes a study of the water resources for the Nooksack River basin. This bulletin is meant to serve as a guide, assisting municipalities, industry, and other public and private agencies by studying the geology, streamflows, groundwater levels, and determining the total water budget for the basin relative to consumptive uses. The study area described in this bulletin includes portions of Whatcom and Skagit counties.
18
Water resources and geology of the Kitsap Peninsula and certain adjacent islands
Water Supply Bulletin 18 (1963) describes part of an inventory of Washington State's water resources from October 1960 to June 30, 1963. This bulletin includes well log data, descriptions of local geology, chemical evaluation of groundwater and evaluation of previous studies. The study area described in this bulletin includes portions of Kitsap, Mason, Pierce, and King counties, WA.
19
Water resources of the Tacoma area, Washington
Water Supply Bulletin 19 (1962) summarizes and interprets information on the occurrence, quantity, quality, and availability of water resources for planning utilization in Pierce County, WA. This bulletin includes flow, sediment, and chemical quality for the Green, White, Carbon, Puyallup, and Nisqually rivers.
34
Water in the Okanogan River Basin, Washington
Water Supply Bulletin 34 (1974) describes the general hydrologic conditions existing in the Okanogan River basin. This bulletin includes historical stream discharge and precipitation measurements, groundwater levels, well log records and water quality analyses for sub-basins in portions of Okanogan County, WA.
38
Water in the Methow River Basin, Washington
Water Supply Bulletin 38 (1974) describes an investigation of the available amount, quality, and the frequency of seasonal water shortages and surpluses in the Okanogan River basin. This bulletin includes historical stream discharge and precipitation measurements, groundwater levels, well log records and chemical analyses for portions of Okanogan County, WA.
39
Water in the Palouse River Basin, Washington
Water Supply Bulletin 39 (1975) describes the general hydrologic conditions existing in the Palouse River basin. This bulletin includes historical stream discharge and precipitation measurements, groundwater levels, well log records and chemical analyses for portions of Whitman, Spokane, Lincoln, Adams, and Franklin counties, WA.
46
Geology and water resources of the San Juan Islands, San Juan County, Washington
Water Supply Bulletin 46 (1975) describes the general hydrologic system, geology, surface water, and groundwater resources of the San Juan Islands. This bulletin includes geologic descriptions, well log records, precipitation, streamflow measurements, and water quality data for San Juan County, WA.
47
Water in the Skagit River Basin, Washington
Water Supply Bulletin 47 (1978) describes the general hydrologic conditions existing in the Skagit River basin. This bulletin includes historical stream discharge and precipitation measurements, groundwater levels, well log records and chemical analyses for portions of Skagit County, WA.
50
Geology and water resources of Klickitat County
Water Supply Bulletin 50 (1979) describes a reconnaissance study summarizing meteorology, geology, surface water, ground water, and water quality data in the Klickitat River basin, to provide basic information for water resource research, management, and use. This bulletin includes stream discharge data, surface and ground water quality data, groundwater level data and well log records for portions of Klickitat and Yakima counties, WA.
51
Water in the Horse Heaven Hills, south-central Washington
Water Supply Bulletin 51 (1982) provides a general interpretation of all available hydrologic information for the Horse Heaven Hills area. This bulletin includes streamflow records, surface and ground water quality, and well log records for selected wells in portions of Klickitat, Benton, and Yakima counties, WA.
52
Hydrology of the Upper Yakima River Basin, Washington
Water Supply Bulletin 52 (1985) summarizes available surface and ground water data to describe the hydrologic setting of the lower Yakima River basin. This bulletin includes records of snowfall, an inventory of glaciers in the basin, storage in major reservoirs, discharges of streams, and analyses of chemical, physical, and sanitary quality of the water and ground water data records of wells, drillers’ logs and water quality analyses. The study area described in this bulletin includes portions of Kittitas and Yakima counties, WA.
53
Water in the Lower Yakima River Basin, Washington
Water Supply Bulletin 53 (1985) summarizes available surface and ground water data to describe the hydrologic setting of the lower Yakima River basin. This bulletin includes records of precipitation; storage of water in lakes and reservoirs; records of discharges of streams, canals and drains; well log records; and analyses of ground water quality in portions of Benton and Yakima counties, WA.
58
The Effects of withdrawals on the hydrology of Samish Lake and Upper Friday Creek
Water Supply Bulletin 58 (1990) evaluates the magnitude of the effects of additional withdrawals from Samish Lake on streamflow in Friday Creek. The study area described in this bulletin includes portions of Whatcom County, WA.
60
Estimated baseflow characteristics of selected Washington rivers and streams
Water Supply Bulletin 60 (1999) evaluates the groundwater contribution to total streamflow (baseflow) at active and inactive stream gaging stations throughout Washington State, using automated hydrograph separation techniques. Discharge records for 582 gaging stations, with at least three complete water years of daily mean streamflow data, were downloaded from the U.S. Geological Survey (USGS) database and analyzed. In addition, station characteristics were compiled for each gage, including period of streamflow record, type and degree of regulation affecting the gage, watershed drainage area, USGS station number, station name, and gage location. This bulletin includes monthly and annual stream discharge summaries for modeled stream gages in Washington State.
