I grew up fishing milford still fish Milford mainly. I have never noticed the algae to affect the fishing, but I don't crappie fish Milford much outside the spawn as i never have much luck with them outside the spawn there. Doesn't affect catfish fishing; big shad eat the stuff. KDHE says it doesn't affect the fish but that you are only supposed to consume the fillet portion of the fish. As far as health issues as long as you don't swim in it it shouldnt affect you. Don't let pets drink the water as it can kill them.
