The Salmon River is formed at the confluence of the Blackledge and Jeremy rivers about one mile west of North Westchester, Connecticut. It drains 96,000 acres and courses for 10.4 miles (16.7 km) to Salmon Cove near Moodus where it flows into the Connecticut River. The Salmon River is probably the largest stream and watershed whose sources and mouth are entirely within the limits of Connecticut.There is a popular paddling route along the Salmon River varying in difficulty from quickwater to Class II whitewater. It begins along River Road about 1/10 of a mile south of the river's formation and continues for about 7 miles to the flatwater of Salmon Cove. The Salmon River's substantial drop in elevation over its course provided considerable water power to the textile mills in Moodus during the 19th and early 20th centuries.

The East Haddam Historic District is a 110-acre (45 ha) historic district in East Haddam, Connecticut representing the historical development of two 18th-century settlements of the town on the east bank of the Connecticut River, Upper Landing and Lower Landing. The district is linear and runs along Route 149. It was listed on the National Register of Historic Places in 1983, and includes a diversity of 18th and 19th-century styles, as well as the town's main civic structures, and the Goodspeed Opera House. Also included in the district are two monuments, one to Nathan Hale and another to Gen. Joseph Spencer, a park, and a cemetery.East Haddam was settled in 1685, and was originally part of Haddam. Ferry service was introduced on the river in 1695, and developed at several points. The Upper and Lower Landings each developed somewhat independently, but over time became united into a long linear village, caused in part by the steep terrain immediately to the east which limited growth in that direction. Both landings flourished up to the American Civil War, as centers of international commerce doing business with the East and West Indies. The landings declined in economic importance after the war, owing to the rise of the railroad as the principal means of commercial transport, which was run up the west side of the river. The southern landing eventually became more significant as a tourist destination, and is where the East Haddam Bridge is now located, as is the village's commercial district.

Connecticut Yankee Nuclear Power Plant (CY) was a nuclear power plant located in Haddam Neck, Connecticut. The power plant is on the Connecticut River near the East Haddam Swing Bridge. The plant was commissioned in 1968, ceased electricity production in 1996, and was decommissioned by 2004. The reason for the closure was because operation of the nuclear power station was no longer cost effective. The plant had a capacity of 582MW. Demolition of the containment dome was completed the week of July 17, 2006. Kenneth Nichols, the deputy to Leslie Groves on the Manhattan Project, was a consultant for the Connecticut Yankee and Yankee Rowe nuclear power plants. He said that while the plants were considered "experimental" and were not expected to be competitive with coal and oil, they "became competitive because of inflation … and the large increase in price of coal and oil." The Connecticut Yankee plant was estimated to cost $100 million.
