TheNepaug River begins at the confluence of North Nepaug Brook and Cedar Swamp Brook about one mile (1.6 km) east of Bakerville, Connecticut.
It runs for 10.6 miles (17.1 km) to theFarmington River about one-half a mile (0.80 km) south ofCherry Brook, Connecticut.[2]
A popularwhitewater paddling route begins along Dings Road about one-tenth of a mile (0.16 km) downstream from the start of the Nepaug River. This river run is between Class I-II whitewater until theU.S. Route 202 bridge. The river then enters the Nepaug Reservoir at the northwest corner.

The Nepaug Reservoir was created by the Nepaug Dam which is located at the northwest corner of the reservoir and is approximately one mile (1.6 km) from the Farmington River. The final section of the Nepaug River carries the overflow from the Nepaug Dam east to the Farmington River at Collinsville (near Cherry Brook, Connecticut). The Reservoir is managed by theMetropolitan District Commission.
The Nepaug Reservoir is approximately two miles (3.2 km) long from north to south and approximately one mile (1.6 km) wide from east to west.
