Minnewashta Lake covers 680 acres and has an average depth of 10 feet. It drops down to around 16 feet at its deepest point, which allows a good amount of fish to stay in this lake throughout the summer even while water temperatures rise.
With you may experience some decent fishing on this lake in the summer, the spring time is the time to fish this lake if you want to give yourself a chance to catch some better numbers of quality fish. In the spring, when the water is higher, there will be some current running through the bridge that connects Upper Gar Lake to Minnewashta Lake. This is a good spot for walleye, northern pike and panfish. During higher water times in the summer and fall, this spot can also produce. The current definitely attracts and helps position fish near the bridge.
Beyond the bridge, this lake does have some other areas that will hold fish. If you fish the drop-offs along the shorelines, you should run into a lot of panfish in the lake. Some anglers do catch some nice bass and pike in the lake too, but the larger lakes in the chain do offer anglers a better chance to catch quality game fish in the summer and fall months.
