Setterguy, I've noticed with my pond that even tho the surface temp is crazy high (94 yesterday), as long as there is cooler water under it with O2, they'll be ok. 87 isn't too bad. But if you have an outboard motor, I'd keep it close by.

My fish seem to be doing fine even tho it's hot on top. When I stirred the pond last week, every bedding fish left and everything quit feeding. Yesterday there were 200 staged on the bank waiting for dinner.

.10 surface acre pond, 10.5 foot deep. SW LA. The epitome of a mutt pond. BG, LMB, GSF, RES, BH, Warmouth, Longear Sunfish, Gambusia,Mud Minnows, Crappie, and now shiners!!...I subscribe!!
