Realizing the impact man has had on our natural environment, we must respond to how he has affected the water's ability to flow in a more limited area.   Historically, water infiltrated into a natural, native landscape that consisted of root systems often greater than 8 feet in depth.   With the reintroduction of a native prairie adjacent to Phillips Pond we have a better opportunity to allow water to act as it did for thousands of years, prior to the introduction of Eurasian plants brought by settlers of the late 1800's.   The need to maintain a more consistent water level of Phillips Pond is mandated by the delicate ecosystem surrounding its edges.  The Weir Bridge stands above the Weir structure, which assists in keeping the water level of the pond consistent throughout the year.
