About two miles south of Granite Falls. Fishing opportunities include stocked Rainbow Trout, resident Coastal Cutthroat Trout, and Largemouth Bass. On August 8th, 2016, the state record Largemouth Bass (12.53 pounds) was caught from Lake Bosworth by Bill Evans of Bothell, underscoring the potential for big bass in western Washington lakes.
This lake is one of only twelve waters in Snohomish County managed with a seasonal fishing closure. Spring catch rates for trout are highest early in the season and decline as fish are harvested and as warmer water temperatures force trout to seek areas of colder refuge. Fall is often overlooked by anglers, but can be an ideal time as fish that have been growing all summer become more active around the lake with cooler temperatures.
A WDFW access on the northeast corner offers boat launching with limited parking, and a toilet. Gasoline-powered motors are prohibited.
