The area around Ramsey county gets treated four and five times a year to kill the weeds. The DNR tells me that they only kill a 50 x 50 foot section, and when I told him that the company uses a firehose and they spray seventy percent of the lake, he called me a liar.
When they spray, it absolutely kills the shallow water fishing for a week to ten days, so you have nearly a month of the growing season with sick, under weight fish. The guy at the DNR said they are always hearing complaints from the shore owners, but never any from the fishermen. I was the only guy who called to complain. That’s why they give out permits like gumdrops. If enough of us complained about it, they might cut back on the spraying.
I remember before they sprayed Owasso four times a summer, it had great cabbage beds, clear water and phenomenal musky fishing. Now, not so much.
