I recently received a note in my inbox from Paul Hoffarth, who is a district biologist in the Region 3 office in Pasco with the Washington Department of Fish and Wildlife. He attached a link to a presentation that revealed the results of 20 years of research on the walleye population in Lake Roosevelt. I found this very fascinating. Some of the highlights were that 80 percent of the walleye in Roosevelt are in the 14- to 16-inch class, and the reason is the very slow growth rate. Around 50,000 walleye are harvested every year by sport anglers, but that doesn't really impact the population. The abundant population is self-sustaining, and there is a very large year class that occurs every two to four years. Most anglers prefer to keep walleye that are 16 to 18 inches or larger and fish over 20 inches are rare. Releasing walleye that are over 20 inches could help improve the number of larger fish it is speculated. If you have an interest in watching this very informative presentation you can follow the link that I have posted on Facebook page or in my weekly column in the Spokane Exchange.
