Terry R. Maret, Jon Hortness, Douglas S. Ott
2005, Scientific Investigations Report 2005-5212
Anadromous fish populations in the Columbia River Basin have plummeted in the last 100 years. This severe decline led to Federal listing of Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) stocks as endangered or threatened under the Endangered Species Act (ESA) in the 1990s. Historically, the upper Salmon...

A computer program for predicting recharge with a master recession curve
Christopher S. Heppner, John R. Nimmo
2005, Scientific Investigations Report 2005-5172
Water-table fluctuations occur in unconfined aquifers owing to ground-water recharge following precipitation and infiltration, and ground-water discharge to streams between storm events. Ground-water recharge can be estimated from well hydrograph data using the water-table fluctuation (WTF) principle, which states that recharge is equal to the product of the water-table rise...
