I think I may be having a low dissolved oxygen event. It was dark cloudy and windless the past two days after a hot sunny spell. We got a cold 1.1" rain yesterday. Fish fed well yesterday morning, not so much yesterday evening. This morning, I noticed almost all the CC and BG gathered in about 10" of water along the banks. No dead fish or piping fish. The FA appears to be dying and sinking. I don't have aeration, but I started pumping in fresh water from my intermittent flow creek along the surface almost parallel to the bank at 9:30 this morning. I am still pumping an hour and a half later, and the BG have moved away from the banks and the CC are moving around more now. Am I doing the right thing? I could pump most of the day if the creek has enough flow. Supposed to get sunny this afternoon, but only 6 MPH breeze. I don't have electricity there to aerate, only a gasoline powered 2" pump that puts in about 3,800 GPH.

1/4 acre pond 11 feet deep. Good sun and wind exposure. Visibility today about 16 inches. Greenish water. Water has cleared considerably since Saturday.

Edit: 3:00 PM. Still pumping. Bluegill behavior has almost returned to normal. CC still in shallows but have moved to about two feet of water and are swimming around some in current coming out of pipe.
