Pataha Creek Fish Passage Rectification RM10
Pataha Creek RM10 is the largest tributary to the Tucannon River. Erosional downcutting is a problem throughout the entire length of Pataha Creek which has contributed to several fish passage issues.
Pataha Creek is the largest tributary to the Tucannon River. Erosional downcutting is a problem throughout the entire length of Pataha Creek which has contributed to several fish passage issues. Prior to 2011, utilization of Pataha Creek by juvenile and adult steelhead trout (Oncorhynchus mykiss) was limited to the lower 0.2 miles of Pataha Creek due to the fish passage barriers located at the SR 261 culvert crossing and a partial passage barrier at the US Highway 12 bridge. In 2011, boulder and log cross-vane weir cascades were constructed downstream from SR 261 and US Highway 12 stream crossings to provide low-flow fish passage. This fish passage rectification project provided fish access to approximately 12 miles of Pataha Creek that were previously inaccessible.
