Updated information on the Tulalip Indian Reservation 's resources indicates that the newly developed tribal well field yielded about 100 million gallons of water during August 1975-October 1976. At 16 or 17 streamflow sites, mean annual discharges during the 1976 water year exceeded those of the 1975 water year by a median value of 25 percent. The levels of John Sam, Ross, and Weallup...

This report presents data assembled during a July 1975 to August 1977 study of the water resources of an area within, and adjacent to, a part of the Fort Lewis Military Reservation that prior to 1917 was included in the Nisqually Indian Reservation. Because the area is within or near the artillery ranges of the U.S. Army, the existing water resources of the study area are almost...

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...

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...

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...

An assessment of water use in 1975 in the 39 counties and 62 Water Resources 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...

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...

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...
