Sandbox, we had an "uncontrolled" burn a few years ago right next to what was to become a portion of our pond shoreline. We accidentally burned about an acre of pine needles and brush below our pine forest before we were able to put it out. Today that area is absolutely magnificent. Grasses have grown on the forest bed and all thorns and vines are gone. The drainage off that area is not eroding the soils. IF I were able to manage a controlled burn I would do it.
Meadowlark, NRCS said the same thing about my pond site. Too much sand and not enough water shed. We are 4 foot shy of being a full 2 1/2 acre pond and have already filled in a good 15 feet of depth. We had been losing about an inch a week if no rain fell, but since the soils have finally saturated I am seeing only a fraction of an inch drop each week. I'm sure when the 100 degree days return it will drop.
