Ecology scientists focus studies on Hangman Creek pollution sources

From Washington Department of Ecology

Scientists from the Washington Department of Ecology are planning several studies to better understand potential sources of pollution to the Spokane River’s largest tributary, Hangman Creek. Hangman Creek suffers from low oxygen, high nutrients and too much sediment in the water.

Millions of dollars are currently being invested to control pollution from urban areas and improve the Spokane River. By studying the creek, scientists will gain a better understanding of the pollution contribution it makes to the river and be able to make recommendations for improving the health of both.
Studies include a survey of streamside vegetation and land use activities and an in-depth look at Tekoa’s wastewater treatment plant.

Starting May 8, field staff will spend several days floating a portion of Rock Creek and Hangman Creek from the Idaho border to the mouth. While floating and making stops along the way, the team will gather data on plant diversity, stream complexity and aquatic insect populations to record the general condition of the creeks. Additional water quality data including nutrients and sediment will be collected through October 2018.
