[Homestead] Fish Kill

Don't know what your specific problem is..... but to increase oxygen in a pond.........
 
Some of aquaculture farms use paddle wheels that are powered and move back and forth across the ponds to stir up the water which stirs in O2.
 
Others build a little mountain of rocks in the center, run a pipe up the middle and splatter water down over the rocks to achieve the same thing.   Other use the same concept but build a wooden float thing, kind of Central America pyramid shaped that the water splashes down over.  
 
Splashing water is the idea.
 
 
Adding crawdads??? might help keep the vegetation level down.

“All political thinking for years past has been vitiated in the same way. People can foresee the future only when it coincides with their own wishes, and the most grossly obvious facts can be ignored when they are unwelcome. Political language... is designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind.” ~ George Orwell

I've mentioned before we live on a three acre pond. Today I see
approximately a hundred dead bluegills, mostly around three inches and
smaller floating around the edges of the pond. They don't appear
malnourished though they probably bloated somewhat to cause them to
float.

We've been in an extended drought which caused the shallow banks to
recede maybe 10 ft in places, and good stands of grasses and weeds
sprouted on that exposed ground. Now that we've had a lot of rain the
pond has been full for about a month and that grass is decomposing. I
suspect this decomposition has depleted the oxygen supply in the water
rapidly and that's causing the fish kill.

Anyone have any thoughts on this?
