ZSL - Zosel Dam Combined

Zosel Dam is located at Okanogan River km 132, approximately 3 km downstream from the outlet of Lake Osoyoos in the town of Oroville, Washington. The dam has two fish ladders and four spillbays. PIT tag detection was established at the dam by attaching antennas to the downstream faces of two weirs in each fish ladder. Each weir has a single vertical slot that is approximately 16 in. wide and 120 in. high. Few juveniles use the fish ladder and, at high water, adults can also bypass the fish ladders by swimming through the spillbays. To detect fish passing through the spillbays, in April, 2015 a 10ft x 4ft floating antenna was added in the west-most spillbay and, on March 16, 2016, a similar antenna was added to the east-most spillbay. These antennas are placed in the middle of the spillbays which are approximately 20ft wide.
