SPOKANE – A draft water quality improvement plan from Washington Department
of Ecology (Ecology) to decrease temperature on the main stem of the Palouse
River is available for public review beginning May 16 through June 14, 2013.
Fish and other aquatic animals need cool, clean water for reproduction and survival.
The plan outlines several ways to improve temperature on the river to meet temperature goals including:
Ecology computer models indicate that much of the Palouse River will be naturally warm in summer months due to climate, and the native vegetation and hydrology of the system. This makes achieving the assigned temperature goal difficult. When the river meets “natural condition” during critical summer months it will be considered in compliance with state water quality standards.
Achieving natural condition for the Palouse River relies on returning water temperatures to historical levels primarily by restoring streamside trees and shrubs. Some additional conditions that affect temperature are groundwater input, sediment, stream width and depth, and discharges to the river.
Plans to reduce historical pesticides, related toxic chemicals and fecal coliform bacteria on both the main stem and south fork of the Palouse River are already in place. A study and report to examine dissolved oxygen, pH and nutrients on the section of the river known as the north fork is currently in development. The South Fork Palouse River study on temperature, dissolved oxygen, pH and nutrients is also in development.
