I don't know the exact terminology--something like heating days or heating hours or something like that...Anyway I think yesterday will have been the worst day of the year. We'll be cooler for the next week, then if it gets hot again we'll have shorter days to buffer that effect a little. I'm pretty stoked that I haven't lost a single fish to heat or oxygen problems in this pond.
Now I just need to take the herons out of the equation. I've caught three perch with spear marks in them, and who knows how many I never did see.
