The Plotter Kill drops 900 feet in its 3.5 mile descent from Rynex Corners to the Mohawk River. There are three spectacular waterfalls: the Upper Falls, Lower Falls and the Rynex Creek Falls at the junction of Rynex Creek and the Plotter Kill. All are magnificent sights in spring high water and in winter ice. The Upper Falls is 60 feet high, and the others 40 feet. The Plotter Kill Preserve is wonderful for nature study. Over 600 species of plants have been found in the area including: trilliums, violets, lilies, ferns and club mosses.
