It flows through just two properties in its lower five miles, that of the Baltimore Area Council, B.S.A. and then the Exelon power company. In its three-mile course through Broad Creek Memorial Scout Reservation, it was dammed to create Lake Aaron Straus and passes close to the Late Archaic Period Broad Creek Soapstone Quarries archaeological site. Downstream from the 1948 Boy Scout dam, the creek forms a noteworthy gorge through the largest and oldest eastern hemlock grove in the state east of the Allegheny Front. At the east edge of the reservation, about two miles from its mouth, the creek meets the headwaters of the reservoir.
