If you can overfish a lake the size of DL....you have a serious pressure problem. We are starting to see it here in northeast SD. Soooo many guides now. Everyone with a minnow bucket and a pole are guiding and they're taking ALL size fish out. I've seen their pics. Its bad. It went to the state to make guides have licenses, ins etc and failed. So we have a million guides in a small area. I saw an ad for a guide on FB and had a pail full of 6 inch bluegills. The pressure is relentless. It won't stop until the fish are gone...and that WILL happen. Regulations are important. People need to not be short sighted. They are happy now cuz fishing is good but what will they say in 7 years when they can't find a fish anywhere. Then they'll bitch again. I fished Rainy Lake years ago. I liked their regs. If I remember right....one fish over 28. Nothing between 17-25 cuz main spawners. (walleyes that is) The pressure will not stop until the fishing takes a dive and.....it will.
