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.

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.

The Haddam Center Historic District is a 267-acre (108 ha) historic district encompassing the institutional and residential center of the town of Haddam, Connecticut that was listed on the National Register of Historic Places in 1989 as a result of efforts by the Haddam Historical Society.The town center of Haddam was first laid out in 1662, when land was set aside for a colonial meeting house, a minister's house, and land for the minister. The town's early growth was slow, because the terrain was not very suitable for agriculture. After American independence, the town began to grow more substantially, buoyed by construction of the Middlesex Turnpike along what are now CT 154 and Walkley Hill Road. The town center grew as a stop on the turnpike, and also benefited from traffic along the Connecticut River, which formed its eastern boundary. The introduction of steamship and railroad traffic beginning around 1850 led to a decline in the town's fortunes.The district is basically linear in nature, extending about 2.5 miles (4.0 km) along CT 154 and Walkley Hill Road. It boasts a fine collection of Federal period residential architecture, and a number of institutional and civic buildings constructed in the mid-19th century out of locally quarried granite. It includes the James Hazelton House, at 23 Hayden Hill Rd., which is separately NRHP-listed, as well as the Brainerd Memorial Library.
