The Swinomish Indian Reservation occupies 17 mi2on Fidalgo Island, northwestern Washington. Six square miles are underlain by mudflats or low-lying alluvial deposits, and are not part of the study area. An appraisal of the water resources of the reservation was made because the Swinomish Tribal Community expects rapid economic and population growth in the near future. Average inflow to...

This reconnaissance evaluation of the sediment transport by the White River into the Mud Mountain Reservoir, in Washington, during the period June 1974-June 1976 showed that the river transported 430,000 tons of suspended sediment into the reservoir during the first year of the study and 1,400,000 tons in the second year. Daily mean suspended-sediment concentrations generally were less...

The anticipated water demand of 425 million gallons per year for the North Beach Peninsula, Pacific County, Wash., can be met by properly developing the ground-water supplies of the area's water-table aquifer. Of the approximately 77 inches of precipitation on the peninsula, an estimated 23 inches is lost to evapotranspiration, and approximately 36 inches is discharged by the water-table...

In 1974 about 30 percent of the nearly 600 acre-feet of water used on the Tulalip Indian Reservation was obtained from a surface-water reservoir, while nearly 70 percent was obtained from ground-water sources. Domestic use accounted for about 93 percent of total water use. Nutrient (phosphorus) concentrations measured in most surface-water samples were less than the maximum limit...

An assessment of water use in 1975 in the 39 counties and 62 Water Resource Inventory Areas of Washington, indicated that 2.49 trillion gallons of water was used for municipal, industrial, and irrigation purposes. That amount represents a 10-percent increase over a similar water-use assessment in 1965, but a slight decrease from that of 1970. Total municipal water use, which includes...

Combined ice and water balances were measured in the 1967 hydrologic year (October 1-September 30) on four glaciers in western North America ranging in latitude from 37 deg to 63 deg N. This hydrologic year was characterized by heavier than normal winter precipitation in California and Washington and abnormally dry winter conditions in coastal Alaska. In summer the western conterminous...

Streams in lowland basins of the Olympic Peninsula, Washington, generally have their low flows in summer and peak flows in winter, whereas streams originating at higher elevations in the mountains have their low flows in late summer-early fall and they have both winter and spring peak flows. Data from long-term stations indicate no important trend in low flows during 1940-73 but they do...

Large quantities of ground water and surface water are available in Washington County. Major sources of ground water are the Gosport Sand and Lisbon Formation undifferentiated, the Miocene Series undifferentiated, and alluvium and low terrace deposits. The Miocene, the most productive source of ground water, will yield 0.5 to 1.0 mgd (million gallons per day) per well and is a potential...
