The pond was built in the 1950's. I just had the entire thing drained and renovated (remove trees from dam, raise spillway and remove the sediment from the bottom).
The years of sediment on the bottom of the pond was deep. I don't want to go to the expense of adding tucklaods of gravel to these new "shelf" spawning areas if it gets buried in the next few years....
I thought a liner (or something like a liner) would help to keep the gravel from buryig in the muck?
