1999 Warmwater Survey of Duck Lake, Grays Harbor County

The warmwater fish population in Duck Lake, Grays Harbor County, was sampled on May 4-5, and 10-11, 1999. A modified Petersen mark and recapture population estimate was completed for the gamefish, as well as a standard warmwater fish survey. The 95% confidence intervals for largemouth bass population estimates range from 11,236 - 14,853 fish over 100 mm, 844 - 3,188 black crappie greater than 100 mm, and 11,305 - 16,009 bluegill over 100 mm. Our recommendation for protecting the bass population and positively altering its size structure is to implement a slot length regulation. Additionally, an angler creel survey should be planned to monitor angler pressure, preference, and harvest.
