QED Posted October 28, 2021 Posted October 28, 2021 Park rangers just posted signs about the title subject at my nearest, small lake. It was a tough lake to fish before. How bad is this new information? Quote
F1SH Posted October 28, 2021 Posted October 28, 2021 What type of toxic algae? My lakes get blue green algae and it doesn’t seem to have any negative impact on the fishing Quote

But F&G also noted that we are having a "natural" fish die off, so it is not the benign type. Quote

Some people get quite sick from it. Around here the BL/Grn was bad this year. Several lakes that are usually lush with weeds were totally void of them with the exception of Lily pads, if they grew there to begin with. Algae blocked the light, so nothing weedy grew. It did nothing to improve the bass fishing, and will definitely hurt this year's class of bass fry. Probably a a total wipeout in the desertified lakes. Quote

QED Posted November 6, 2021 Author Posted November 6, 2021 Update: An additional, fish die off factor can be algae toxicity: "More directly, fish can be killed by exposure to HAB toxins in the water, or in prey consumed by fish." https://hab.whoi.edu/impacts/impacts-wildlife/fish-kills/ Regardless of the dominant cause of fish die off, conditions will be tougher at Grant Lake.

Tom Thanks, that's good to know. Right now, it doesn't appear to be the golden variety, but it is causing bad results regardless. Quote
