Washington

Washington's Puget Sound is a complex ecosystem directly adjacent to a robust metropolitan area that scientists from the USGS Western Fisheries Research Center study. Recent surveys have looked at juvenile surf smelt, a key link in the food web that are consumed by predators such as salmon, orca, and many marine birds.

Advances in ice radar studies of a temperate alpine glacier, South Cascade Glacier, Washington, U.S.A.

South Cascade Glacier, Washington, U.S.A., is one of the most extensively studied glaciers in the Western Hemisphere. In addition to mass-balance measurements, which date to 1958, numerous hydrological investigations have been carried out during the last three decades, and repeated ice-thickness determinations have been made using a variety of...

Use of a ground-water flow model with particle tracking to evaluate ground-water vulnerability, Clark County, Washington

A ground-water flow model was used in conjunction with particle tracking to evaluate ground-water vulnerability in Clark County, Washington. Using the particle-tracking program, particles were placed in every cell of the flow model (about 60,000 particles) and tracked backwards in time and space upgradient along flow paths to their recharge points...

Ground-water pumpage in the Willamette lowland regional aquifer system, Oregon and Washington, 1990

Ground-water pumpage for 1990 was estimated for an area of about 5,700 square miles in northwestern Oregon and southwestern Washington as part of the Puget-Willamette Lowland Regional Aquifer System Analysis study. The estimated total ground-water pumpage in 1990 was about 340,000 acre-feet. Ground water in the study area is pumped mainly from...
