Total streamflow across the Black River was last observed at 67,944 cfs, and is expected to yield approximately 134,766 acre-ft of water today; about 118% of normal. Average streamflow for this time of year is 57,416 cfs, with recent peaks last observed on 2011-05-04 when daily discharge volume was observed at 476,781 cfs.

Maximum discharge along the river is currently at the Black River At Elgin Ferry reporting a streamflow rate of 24,500 cfs. However, the streamgauge with the highest stage along the river is the Black River Ds St Hwy 54 @ Black River Falls with a gauge stage of 35.99 ft. This river is monitored from 23 different streamgauging stations along the Black River, the highest being situated at an altitude of 5,759 ft, the Black River Blw Pumping Plant.

The Black River is a river in the northeastern United States that flows through the states of New York and Pennsylvania. It is approximately 125 miles long and has a drainage area of 1,230 square miles. The river is known for its hydroelectric power generation, with several dams and reservoirs built along its length, including the Neversink Reservoir and the Pepacton Reservoir. These reservoirs provide drinking water to New York City and the surrounding areas. The Black River also has recreational uses, with fishing, kayaking, and canoeing opportunities, and the river's valley is home to a variety of wildlife. The river has played an important role in the history of the region, having been used for transportation, logging, and agriculture.

The Bafing River runs through Guinea and Mali and is about 760 kilometres (470 mi) long. It joins with the Bakoy River at Bafoulabé to form the Sénégal River in the Kayes Region of western Mali. In Manding languages, Bafing signifies 'black river' and Bakoye 'white river'. The Bafing forms part of the international border between Guinea and Mali.
From 1895 to 1898 the railway bridge near the town of Mahina, designed by Gustave Eiffel, was built.
The Manantali hydroelectric dam is located on the Bafing River 90 kilometres (56 mi) upstream of Bafoulabé. It forms the largest artificial lake in Mali, Lake Manantali. The dam retains 11.3 cubic kilometres (2.7 cu mi) of water which is used to power the turbines during the dry season. As a result, the intensity of the maximum flood downstream of the dam has been reduced but during the dry season, a flow of between 150 m3/s (200 cubic yards per second) and 200 m3/s (260 cubic yards per second) is maintained.
