Two acre pond aeration
Howdy!
I've been prowling through the archives here looking from some good advice on aeration of a large pond. I live in central Texas and just finished digging our pond about two months ago. When full, it will be approximately 2 surface acres and contain (my best guess) a little over two million gallon. I have seen and read about powered aeration systems, but am concerned about operation cost. Ones that seem large enough seem to draw hundreds of watts or electircity, which translates into $25-40 per month to operate. My water is a nice green color and visibility is currently at 3-4 feet, but there is only about five foot of water in it. The average depth will be 9-10 feet with some low spots in the 11 foot range. It will be stocked with catfish, bass and bluegill. Not heavily stocked nor heavily fished. Help! |

There have been a number of discussions on rec.ponds over the last few
years. Do a google groups search with key words "acre pond aeration" and group as rec.ponds. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Thanh Rodke" wrote in message om...

[snip] The average depth will be 9-10 feet with some low spots in the 11 foot range. Your best guess, is way too low :) 2 acres is 87120 square feet, Assume an average depth of 10 feet (let the 9 and 11ft spots even out) That gives us 871200 cubic feet of water. 1 cubic foot of water is 7.48 gallons. That gives you approximately 6.5 million gallons. About 3 times more then what you estimated. Any kind of mechanical method of circulating the water is going to draw a lot of power, to circulate 1 million gallons of water a day, you'll need a pump capable of about 41000 gallons an hour, or 700 gallons per minute. A large air pump, in the 3/4 to 1 hp range is likely to also be energy thirsty as well. Depending on how much wind you get, I've seen some windmill powered airpumps that could help you save some money. Maybe one or two windmills might do the trick. Snooze |

Here's a link for windmills I saw in one of the prior posts talk about barley strawfor reduction of algae. In my 1/2 acre pond it has seem to work very well I also use copper sulfate once a year to make sure I don't have any problems. Keep us informed and good luck.

Thanks to everyone who responded.
I do have an inflow and outflow of water. It is supplied by a very small underground spring and a wet weather tributary. The trib runs about 6-9 months of the year and varies during non-raining periods between 20-50K gallons per day. As such, my only real issues may occur during the summer months when there is not pass-through water. Do barley bales become 'used up' at some point? IE, what is their useful life in controlling algae? One thing to note on the gallon calculation. The pond is U shaped and the cals listed do not account for the 3:1 banks. At most, I'll be in the 2.5 M gallon range. Be design, my full flood stage is over 15 M gallons. However, this would only occur during a 100 year rain. I will probably never see it. I have outflow culvert capacity (two 3-foot and two 4-foot) of about 10 million gallon per hour. During that rain, I am sure it will destroy my pond by flushing the fish down stream....Of course, water will be about 50 foot from my front door as the spillway is being overran....I don't imagine I'll care about the fish at that point!!!!! Thanks again!!!! |
