Regarding Eurasian Water Milfoil, last I heard bass fisherman love it. Regarding zebras, I have said all along that while it may be true that they will flourish after introduction to a new lake, they will eventually find an equilibrium based on the food supply in the lake. Osakis was infected a few years ago. Just a couple weeks ago I was talking with one of the lake shore owners and asked him what he has seen. He said at first, the zebra muscles were all over his docks and boat lifts in the fall when he pulled them out of the lake, however, for the past couple years they have not been so thick. In fact, last fall when he pulled out his docks he counted seven muscles attached. I have also heard reports that fish and other aquatic animals have now begun feeding on zebras. One species in particular that I've heard mentioned is sunfish. Maybe the lakes will have too many jumbo sunfish now?
I haven't been out for while but one thing I find that brings a little success, especially in late summer, is long line speed trolling with crankbaits over shallow water. By speed trolling I'm talking about 3 to 5 mph and by shallow water I'm talking about 10' or less. I've found success doing this while breaking all the rules. For example, one day I connected with a few 20"+ eyes over 8' of water around 1:00 in the afternoon on a calm, bright sunny day. The water was like a sheet of glass.
The challenge for you will be to find those areas where you can troll cranks so they bang the bottom, which means locating those areas under 15' that are virtually weedless. I won't give you the exact coordinates but consider the south town bay area for one. Have fun!
Well I'm up until Wednesday and got out for the first time this afternoon. I went right to one of my favorite lead core spots and it was game on. Alot of 15-16" fish. I was running 26-28 feet. Multiple colors of cranks worked. Shads and flickers both worked. Lots of trollers out. Probably the most I've ever seen on a day.
Some of the lakes where the otter tail river leaves, offer some shore fishing areas, both on the river and the lake. I caught a few hammer handle pike, but there were sunnies swimming all over the place.
