The fishing has been lousy in my local lake. I suspect it's because the hot weather has caused a huge bloom in the marine plant life, which is sucking the oxygen from the water. Could I be correct?

Hi DougMo

Yes, you could be correct.

I don't know about depriving oxygen, but blooms can and do cause problems. You could ask your local fisheries or wildlife dept if they have any info on it.

Good advice! Thanks!
