Crowley Lake in Calfornia

DIY Guide to Fly Fishing Crowley Lake in California

Crowley Lake’s value as a trout fishery is no secret, and it shows. Between 6,000 to 10,000 anglers make their way to the reservoir every year for opening day.

The largest brown trout ever caught on this lake weighed 26 pounds, and intrepid anglers from all over the world flock to Crowley Lake yearly, hoping to break that record.

Even though the Lake is one of the most frequented fisheries in the state, there are still plenty of trout to go around.

The California Department of Game and Fish stocks the Lake with over 200,000 brown and rainbow trout in the late summer and fall, which helps guarantee a productive fishing experience for every skilled angler who visits. 

Fly Fishing in Crowley Lake

Crowley Lake is a reservoir located on the upper Owens River in southern Mono County, California. It is about 15 miles south of Mammoth Lakes. It is named after Father John J. Crowley, a well-known figure in local history.

After the city of Los Angeles’s use of the water supply made agriculture in the Owens Valley impossible, Father Crowley rallied many of the residents who had lost hope into believing that their home could be a popular tourist attraction.

Father Crowley died in a car accident in 1940, but his vision was ultimately realized: Lake Crowley is a premiere fishing destination that attracts fishermen from the entire country.

The Crowley Lake is a man made reservoir formed from the damming of the Owens River Gorge. At Crowley Lake, you’ll see many species of rainbow trout and brown trout, along with some large cutthroats. Because of its ideal pH level, the Lake has a thriving aquatic ecosystem.

Crowley Lake is fed by numerous creeks, including the Upper Owens River, McGee Creek, Convict Creek, Hilton Creek, and Crooked Creek. 

The fishery is only accessible from Crowley Lake Fish Camp, which is run with the cooperation of the Los Angeles Department of Water and Power. At the Fish Camp, visitors can rent boats and buy supplies for angling.

Many anglers use float tubes to fish, but this can be dangerous if there are strong winds. It’s recommended that you wear a personal flotation device at all times if you are tubing on this Lake. The mudflats around the banks can also be treacherous, so be sure to use caution when traversing this area.

The season for fishing Crowley Lake is standard California trout season. From August 1 to November 15, it is restricted gear season. You are only permitted to fish with inorganic baits, with a limit of two fish per day over 18 inches. Only barbless artificial lures are allowed.

The trout in Crowley Lake owe their large size to the rich aquatic insect population. The Lake has an excellent chironomid population, and many of the larger trout also feed on the Sacramento perch in the fall months.
