Tracy I think you need a good analysis on how close you are to carrying capacity.
Eric, If I have learned anything over the past 5 yrs it's that mother nature has a strong input when it comes to pond management. Mother Nature will make any corrections needed in a body of water, or on a piece of land. No mater what you do, when MN needs to correct things it will, The problem is, what I want and what MN wants are two different things. No matter if it's Ponds, Quail numbers on a given piece of land or the number of deer, mother nature makes the corrections.
Al, it's funny I think. We have to laugh at what it cost to do any type of solar system that actually works when it is needed. I can get solar to do the job, but it may be 20,000 bucks to get there. Double what it would cost to run electricity to the pond. Look back at houses/homes. where there were large kick backs from the government. It was or is the only way anyone could justify adding a solar system to a house.
I am now in the process of hiring some help for raking vegetation at the pond. Not a management company because I have yet to find a company to manage aquatic vegetation, Hoping to find someone that is willing to show up for at least a two week job or maybe a months works. H E double LL. I could see where it could turn into a full time job.
