““Threatened” Threatened” Teanaway SalmonidsTeanaway Salmonids

In 1999, certain Teanaway In 1999, certain Teanaway salmonids were listed as salmonids were listed as “threatened” under the “threatened” under the Endangered Species Act:Endangered Species Act:– Bull Trout Bull Trout – SteelheadSteelhead

How Can We Reduce How Can We Reduce Teanaway Water Teanaway Water Temperatures?Temperatures?

1) 1) Restore riparian vegetationRestore riparian vegetation -- -- increase shade and stabilize banks increase shade and stabilize banks

2) 2) Increase instream flowsIncrease instream flows -- -- greater water volume stays coolergreater water volume stays cooler

3) 3) Reduce sediment inputsReduce sediment inputs -- -- restore more natural width/depth restore more natural width/depth ratios, deeper water stays coolerratios, deeper water stays cooler
