Here is my story.
Pond Location - South Louisiana
Size - 4 acres and 3 to 6 feet deep

Pond was drained and the banks were rebuilt to provide a 3' drop to eleminate previoulsy shallow areas that were 1 to 2'.

Pond was stocked as follows.
11/03 - 4000 bg, 400 channels
6/04 - 400 northern bass

Events.
7/04 - Floating Algae covers the pond
7/20 - Pond co-owner sprays algae w/Cutrine-Plus
8/8-14 - Unusual cool spell, algae was not effected by the spraying.
8/14 - Pond co-owner sprays algae w/Cutrine-Plus
8/17 - Pond turned green (like an algae bloom)
8/21 - Algae begins to die
8/29 - Fish in distress, not feeding
8/30-31 - Fish kill
9/1 - Kill seems to have stopped

Damage, this is what was counted;
Bream dead - 861, 3-5 inch
Catfish dead - 108, all 8-12 inch
Bass dead - 248

These are actual numbers counted to the best of our ability, I assume actual kill numbers to be higher. Bg and cats spawned this spring, many small catfish and some large are still seen in the pond. I will be out fishing over the next 2 days to see if we have any large bg and any bass at all. I also need to mention that we had caught bg larger than what was found dead and I need to find out how many are left from the spring and August spawn.

I beleive that too much vegetation was killed at one time causing an oxygen depletion, but the mystery to me is the seeming algea bloom that occured after we sprayed, this cut visibility way down and may have had a part in the algea dying and or the oxygen depletion when it died. My friend the algea is already comming back.

All thoughts, ideas and suggentions on what happened and what to do next are apreciated.

Thanks,
