The same thing happens in the small backyard ponds as in your 2 acre pond,
only they don't realize apparently............If you can see 3-4 feet down,
then congrats.... You have a healthy pond....Started filling about 2 months
ago and its turning green? Congrats again...Its a healthy pond....What have
you planted around it for erosion control? Check websites at your local
county gov on retention pond make-up and find lists for which plants to and
not to use . Check your local Home Depot/Lowes for leftover Christmas trees
for great underwater fish cover as well as lining problem parts of the
banks....They get marked down to .01 here on the 26th of Dec.... Aeration
will occur naturally when the temps change and the water temp in the depths
change.... Stratification is the term to Google...It will explain a whole
lot more on what is happening in your pond...Then there is winter draw down
time, liming the pond, fish species ratios, etc. which all actually gets
into a whole lot more fun than the typical "backyard" hole...... If you get
bales of Barley Straw in there that will help reduce most of the algal
mess...Is there an inflow and outflow? (creek or natural underground spring)
If so then there is also a source of aeration/exchange.. Largemouth bass,
bluegills, redear sunfish, and channel cat make the best mix for stocking
warm water ponds. All but the bass should be stocked now in November........
Theres more out there.....
