Water resources of the Cook Inlet Basin, Alaska
Geoffrey W. Freethey, David R. Scully
1980, Hydrologic Atlas 620
Ground-water and surface-water systems of Cook Inlet basin, Alaska, are analyzed. Geologic and topographic features that control the movement and regional availability of ground water are explained and illustrated. Five aquifer systems beneath the most populous areas are described. Estimates of ground-water yield were determined for the region by using...

Water resources of the Makah Indian Reservation, Washington
N. P. Dion, Kenneth Lyle Walters, L. M. Nelson
1980, Water-Resources Investigations Report 80-15
The residents of the Makah Indian Reservation depend on the streams of the area for their fisheries and domestic water supply. The temporal distribution of streamflow in the study area is closely related to the amount and distribution of rainfall. In a year of average precipitation about three-quarters of the...
