Hydrology of Fishing Creek (North Branch Susquehanna River tributary)
# Hydrology of Fishing Creek (North Branch Susquehanna River tributary)

Fishing Creek is a tributary of the Susquehanna River, in Columbia County, Pennsylvania, in the United States. Hydrology involves the discharge, the pH, the chemical hydrology, the dams, and the water temperature. Data has been gathered from a United States Geological Survey gauging station near Bloomsburg, Pennsylvania. The pH of the waters in the Fishing Creek watershed ranges from 4.9 to 8.5 in various places.

## Discharge

Approximately 1 mile (2 km) downstream of Orangeville, Fishing Creek's discharge averages 615 cubic feet per second (17.4 $m^3/s)$ per second and its median discharge is 361 cubic feet per second (10.2 $m^3/s)$ second. The creek's lowest recorded discharge rate in that location is 90 cubic feet per second (2.5 $m^3/s)$ in 1962 and its highest was 2,580 cubic feet per second (73 $m^3/s)$ in 1981. Further upstream, in Benton, Fishing Creek's discharge is almost always less than 720 cubic feet per second (20 $m^3/s),$ and is far lower during the summer, usually approaching 0. The typical discharge of Fishing Creek at this location is around 540 cubic feet per second (15 $m^3/s).$ The streambeds of West Branch and East Branch Fishing Creeks commonly run dry in the summer. In dry years, they are dry for 105 days on average, while in wet years they are on average dry for 5 days.

At a stream gauging station near Bloomsburg, Fishing Creek's discharge ranged between 10 cubic feet per second (0.28 $m^3/s)$ and 5,350 cubic feet per second (151 $m^3/s)$ between 2002 and 2012. The lowest discharge recorded during this time occurred on November 9, 2004. The highest discharge recorded during this time occurred on September 23, 2003.

## pH

Near Benton, Fishing Creek's pH ranges from around 5.6 to around 7.25. Near Camp Lavigne, it ranges from 5.5 to 7.1. East Branch Fishing Creek is the only stream in the watershed whose pH drops below 5.5. Its pH can be as low as 4.9. West Creek and Coles Creek are the least acidic streams in the Fishing Creek watershed. Their pH is usually above 6.3 and often above 7. Typically, Fishing Creek and its tributaries are not at risk for being too acidic for the optimal health of fish, but in early spring during snowmelts, the pH levels near the limit that brook trout can tolerate. Fishing Creek's waters are acidic due to acid rain.

The waters of Fishing Creek at a gauging station near Bloomsburg had pH levels ranging from 5.8 to 8.5 between 2002 and 2012. The lowest pH during that time (5.8) occurred on December 17, 2003.

A dam was built on Fishing Creek in the northern reaches of Bloomsburg with the purpose of powering nearby Irondale furnaces. Additionally, a dam was built on Fishing Creek about 2 miles (3 km) north of Bloomsburg in 1818 by John Barton. In the 1800s and early 1900s there were two other dams on Fishing Creek. One was in Orange Township, and the other, a 212-foot (65 m) concrete dam, was in Orangeville. A dam known as the Benton Dam was built on upper Fishing Creek, directly upstream of Benton.

## Water temperature

The highest water temperature of a stream in the Fishing Creek watershed is that of West Creek, which can reach 77 °F (25 °C) in the summer. The water temperature of Fishing Creek in Benton can reach 75 °F (24 °C) in the summer. The water temperature of Coles Creek, a tributary of Fishing Creek, only reaches 66 to 68 °F (19 to 20 °C) in the summer. In the winter, the water temperature of the main stem of Fishing Creek is around 32 °F (0 °C), and West Branch Fishing Creek's temperature can reach as low as 28 °F (−2 °C) in the winter, making it the coldest stream in the watershed during winter.

At a gauging station near Bloomsburg, the water temperature ranged from 32°F (0.1°C) to 78°F (25.7°C) between November 2002 and November 2012.
