I have a spring feed pond in our woods that we calculated at about 85,000 gallons (60 feet diameter with areas of 7 feet or more). The pond is 50 years old on family property. We recently build a house on the property and I've been working on improving the pond.
It had a leak behind the dyke from a pipe my grandfather used to drain water during construction. The overflow is totally blocked with dirt, however the pond level is well below the overflow.
Once I fixed the leak and mucked out the source of the spring, water began to fill up the pond again. I caught two nice sized bass (10-12 inches) and several sunnies. I also stocked the pond with some small catfish and redear, along with some minnows. I can see the sunnies spawning in the holes they made in the silt.
I've added a bail of barley and used some BZT enzymes to help with the main problem of decaying leaves. The pond had lots of branches and fallen trees, which I removed using a 1/2 inch nylon rope and a 4x4 (lot's of work). I even mucked it somewhat with a grapping hook by throwing it into the center and dragging it out (I may switch to the bedspring idea from this site).
I have two main problems -- first off we have had little rain in the Maryland area and the spring has stopped running. Additionally, even with the bailey straw and BZT the water is still dark brown, although the spring flows clear. However, my first attempt at testing the water showed good oxygen levels with nitrates and ammonia with a safe range.
The Maryland fisherie gave me some small bass and advised against introducing any new plant life. Their idea is that all plants are weeds and they will find their way into the pond from the water foul (which we don't have). I'm tempted to plant some deep water oxygenators anyway.
After all that explaination here are my questions --
1) can I do anything to reinvigorate the spring such as augering down a few feet
2) what sort of plant life would be recommended to handle the mirky brown water (I imagine it is from the tanins in the leaves)?
PS I'm enjoying the country life after moving from a townhouse and I just happened to stumble upon this helpful site.
