Improving Stream Conditions

Water conservation practices and restoring river function are helping improve streamflow across the region.

Long-term data exists for only two gauges, but a newer gauge (2002 through 2019) in the Tucannon River shows promising results. The Tucannon River did not exceed 74 degrees Fahrenheit for a daily maximum from 2005-2019 (data is still being reviewed for 2020). The lower temperatures likely are a result of restoration projects that have set dikes back and planted the riverbanks.

Streamflow remains a challenge, primarily in the Walla Walla watershed. For the rest of the region, improvements to streamflow are anticipated as natural processes are restored.
