The reservoir is continuing to slowly fill up. Water levels are currently just below full pool and slowly rising. Mongold State Park boat ramps, the main boat ramp at Detroit Lake State Park, as well as Hoover and Kane's Marina are all available. When the weather is nice, especially on weekends, the boat ramps can get crowded, so plan ahead. Pretty much any technique will catch fish, but it might take some experimenting to find out what is most effective on the day you're out there.

The reservoir gets stocked with trout during the late spring and summer. As a reminder, anglers are allowed to keep up to five trout, with an additional ten kokanee. It will be stocked again this week with about 8,000 one-pound hatchery trout. Kokanee fishing has started to pick up. Anglers report decent catches lately. Juvenile spring chinook are also active this time of year, feeding and trying to figure out how to migrate downstream. Anglers need to be able to tell them apart from kokanee and release any chinook unharmed.

It's always a good idea to check the water levels at the U.S. Army Corps of Engineers website before using the boat ramps. For the latest information on water levels at Detroit Reservoir check with the Army Corps of Engineers' website for more information
