This small second order stream starts at James Pond on the Exeter/West Greenwich line. It primarily flows through Richmond to its confluence with the Pawcatuck River. Much of the Beaver River passes through protected areas such as the RIDEM Hillsdale Conservation Area and The Nature Conservancy’s Beaver River and Grassy Pond Preserves. The Beaver River is an excellent brook trout habitat. The river supports healthy populations of insects that provide food for fish and birds. Many small vernal pools dot the nearby landscape. They provide breeding areas for wood frogs, spotted salamanders and fairy shrimp. The southern portion of the river is fairly flat, supplying irrigation water for agricultural fields. Wetlands dominate the surrounding land mass as the stream nears the Pawcatuck River.
