Recent rain and snow melt has brought the water elevation up in the reservoir and Mongold boat ramp is again usable to launch boats. This time of year, there are holdover trout and kokanee available. With a bit of spring-feeling in the air, fish should be on the bite.
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 spring and summer with many of these fish still available throughout the fall and winter and into next year. As a reminder, anglers are allowed to keep up to five trout, with an additional five fish kokanee bag limit. Kokanee fishing is mostly done for the year as the adults are moving up into the tributaries to spawn.
Also, as a reminder to anglers, fishing for and harvesting Chinook in the lake and the rivers above is prohibited. Any Chinook caught in Detroit must be released unharmed. Make sure you can tell the difference between a Chinook and a kokanee before you get out on the water.
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.
Anglers are encouraged to report their catch on an on-line form. Remember to indicate whether the fish you catch have their adipose fin or not. This information will allow ODFW to manage the fishery for the benefit of both recreational anglers and the resource.
