Pennypack Creek Improvements – Philadelphia PA

Description

“In nearby reaches of the creek trout fishing is popular. During the season scores of fishermen in hip boots wade the stream, casting for the elusive trout in water once teeming with catfish. To improve trout breeding a number of retards of twigs and stone have been installed by the WPA, with runways or deflectors, which quicken the flow of water in sluggish places. These devices not only serve to aerate the water, but provide shelter in times of flood.”
