Benson Hollow is a tributary of Bowman Creek in Wyoming County, Pennsylvania, in the United States. It is approximately 0.9 miles (1.4 km) long and flows through Eaton Township.[1] The watershed of the stream has an area of 1.82 square miles (4.7 km2). Benson Hollow is a first-order stream and is not designated as an impaired waterbody. The surficial geology in its vicinity consists of Wisconsinan Outwash, alluvium, Wisconsinan Till, bedrock, and a lake. The stream's watershed is designated as a High-Quality Coldwater Fishery and a Migratory Fishery.
Course
Benson Hollow begins in a valley to the west of Cedar Ledge in Eaton Township. It flows south-southeast for a few tenths of a mile before turning east-southeast. Several tenths of a mile further downstream, the stream reaches its confluence with Bowman Creek.[1]
Benson Hollow joins Bowman Creek 1.72 miles (2.77 km) upstream of its mouth.[2]
Hydrology
Benson Hollow is not designated as an impaired waterbody.[3]
Geography and geology
The elevation near the mouth of Benson Hollow is 584 feet (178 m) above sea level.[4] The elevation of the stream's source is between 1,340 and 1,360 feet (408 and 415 m) above sea level.[1]
During the Ice Age, glacial meltwater from Benson Hollow helped form a delta in the valley of Bowman Creek. There is a "deeply notched" col at the stream's headwaters.[5]
Near the culvert, Benson Hollow has a streambed made of gravel with an average grain size of 45 millimeters (1.8 in). The stream is a Rosgen C Type stream and does not have large loads of debris.[6] The surficial geology along the lower reaches of the stream, but alluvium and a lake occur in the upper reaches. The stream's valley is flanked by Wisconsinan Till and bedrock consisting of sandstone and shale.[5]
Watershed
The watershed of Benson Hollow has an area of 1.82 square miles (4.7 km2).[2] The stream is entirely in the United States Geological Survey quadrangle of Tunkhannock.[4]
Benson Hollow is a first-order stream.[6]
A single-barrel culvert carries Benson Hollow in one reach. The culvert passes a 25-year maximum design flow. Areas of deposition occur upstream of the culvert and a large scour pool occurs downstream of it. These phenomena are typical of such culverts.[6]
History
Benson Hollow does not have a name of its own, but takes its name from the valley through which it flows.[2] The stream's valley was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1169270.[4]
Biology
The drainage basin of Benson Hollow is designated as a High-Quality Coldwater Fishery and a Migratory Fishery.[7] Wild trout naturally reproduce in the stream from its headwaters downstream to its mouth.[8]
