Outside the period of record: In the flood of October 10, 1903 this station reached a discharge of roughly 46,000 cubic feet per second (1,300 m3/s)[8]
Fishing
The West Branch is tailwater fishery. This means the same cold water releases that keep it cooler in the summer, keep the river a little warmer in the winter and early spring. The upper section can be cleaner than other rivers during periods of heavy runoff. During high water on the Cannonsville Reservoir, many bait fish spill over the dam. These factors all provide and excellent environment for trout to thrive in.[9]
The trout population in this river is naturally reproducing, during the warm months stocked trout from smaller and warmer tributaries will seek sanctuary in its cool water. The West Branch Delaware River was divided into two sections when the Cannonsville Reservoir was formed. Downstream of the Cannonsville Reservoir, there are large numbered wild populations of brown trout and rainbow trout and an occasional brook trout can be caught although none are stocked. Seasonal anadromous runs of american shad with reports of occasional striped bass.[10] This section is considered one of the best fly fishingtrout streams in the United States, due to the cold water released from the reservoir.[11]
