A lake in the U.S. state of New York is fed by a watershed consisting of a single river on its northern end. For many decades this watershed has been forested. However, recently all of the trees on the northern end of the lake were logged. The roots were also removed, and all that remains is bare soil. What effect will this logging have on the watershed's hydrology over the next few decades? How will these effects influence the concentrations of nitrogen and phosphorus in the lake?
