It is often desirable to have fluctuating water levels in a wetland. We built a small wetland above a 1+ acre pond. It is quite small and does not go completely dry. Currently, the sound of spring peepers is deafening at dusk. With no fish in the wetland, the frog population is incredible. The tadpoles and frogs feed the herons and mink, and many migrate to the pond and feed the fish. We are working with a company to put a 2 acre forested wetland mitigation on another piece of ground on our farm. We have discussed what we want in the plan but only the survey has been completed so far; no plan yet. The advantage is no cost to us; the disadvantage is permanent loss of development rights. We are pretty excited about the project, but progress has been very slow. I guess this is another disadvantage.
