Cam:
I hope this response isn't too general to be of any use.
If you actually have a need (or even just a concern) to provide short term emergency aeration, O2 can be added to the water with outboard motors, mowers/bush hogs on tractors, trassh pumps splashing water from the pond back into it; any number of means to churn up the water. On a small pond, emergency horizontal aeration could even be done with a trolling motor and battery (although I'm not sure emergency horizontal aeration would always be a good idea).
You might want to start a thread under aeration, giving your questions concerning it and details about the pond - size, depth, age, surrounding areas (trees, IIRC). I have been able to glean that electricity is not immediately available at the pond. Do you have access to electricity farther away from it? Long term, aeration can be sent to the pond via a pipeline for the air.
Thanks Theo, I'll go over to the aeration section with this. I think I have a problem with oxygen content in there but am so ignorant of anything having to do with ponds even though I've been reading I just am having trouble sorting it out. I know it's kinda funny but I suffer from oxygen deprivation myself so have a fuddled brain - ain't that a kick? No really! Anyway, I used to have a really good functioning brain but now it's hard to follow certain things and math I don't even try - hence the size of my fish are measured by how big they are in relation to cement blocks.
Well, away I go over to aeration...
