Abstract

Ozette River and Ozette Lake and its tributaries in Washington have many of the water-quality and stream-hydraulic characteristics that are generally supportive of good sockeye salmon production. Ozette Lake is a large, deep lake and a natural rearing area and for young sockeye. In the summer of 1976 water temperatures preferred for the growth of young sockeye (45-68 degrees Fahrenheit) occurred between about 200 feet of depth and the water surface, or generally in the zone of steep temperature gradient. Dissolved-oxygen concentrations in excess of 8.0 milligrams per liter at all depths throughout the year provided an adequate supply of oxygen for sockeye production. In comparison with eight other sockeye-producing lakes in Washington and Alaska, the concentrations of zooplankton in Ozette Lake appear adequate to support the rearing of sockeye salmon. In Big River and Umbrella Creek, tributaries to Ozette Lake, the streambed areas with gravels suitable for spawning were calculated to be about 39,000 and 31 ,000 square yards, respectively. If those areas were completely utilized they would accomodate about 13,000 and 10,000 spawning sockeye females, respectively. (Woodard-USGS)
