The Lower Haw State Natural Area is the former Haw River Division of Duke Forest. It runs on both sides of the river from just south of the old Bynum Bridge to just beyond the US 64 bridge, where it meets up with land already protected for Jordan Lake. Identified in the 1992 Chatham County Natural Heritage Inventory as an area of statewide importance, the property boasts multiple significant features, including providing habitat for rare species and providing more than four miles of river and stream buffer to protect the water quality buffer of Jordan Lake, which serves as drinking water source for many Triangle-region communities.
