Along Valley Road lay several areas where underlying abandoned mine workings have caused the ground to collapse. Before this project was completed, these areas, commonly known as crop falls, would fill with rainwater and stormwater runoff and flow into the mine workings below, recharging the Pine Knot minepool. Eventually, this tainted water would flow out of the Pine Knot Discharge and into the Schuylkill River.  In an effort to prevent this, the Schuylkill Headwaters Association diverted the path of the rainwater and stormwater runoff directly to the West Branch of the Schuylkill River away from the cropfalls preventing the water from becoming polluted.
