Carson Beach takes its name from early settlers in the Inchelium area, though specific historical records documenting the exact Carson family or individual remain elusive in available sources. The beach sits along the shores of Franklin D. Roosevelt Lake near Inchelium, a community on the Colville Indian Reservation in Ferry County. Inchelium's own name derives from the San Poil Indian language, with the original En-char-lay-um or En-ch'lay-um meaning "where big water meets little water" or "a meeting place among three waters," referring to the confluences of Hall and Stranger creeks with the Columbia River. The original Inchelium townsite disappeared beneath 135 feet of water when Grand Coulee Dam created Franklin D. Roosevelt Lake in 1941, with residents relocating to the benchland above the new reservoir while maintaining their community's traditional name. The lake itself honors President Franklin D. Roosevelt, who championed the Grand Coulee Dam project during its construction as part of New Deal infrastructure development. Carson Beach emerged as one of several access points along this massive reservoir that stretches 130 miles through northeastern Washington, providing recreational opportunities on lands that hold deep significance for the Confederated Tribes of the Colville Reservation, whose twelve bands historically inhabited these river valleys before the dam's construction transformed the landscape.
Carson Beach offers visitors access to Franklin D. Roosevelt Lake's extensive recreational opportunities within the Lake Roosevelt National Recreation Area managed by the National Park Service. Swimming ranks among the most popular summer activities, as the lake's shallow beachfront areas warm considerably during the warmer months despite the reservoir being fed by glacial melt and snowmelt from the Canadian Rockies. The beach provides ideal swimming conditions with gentle slopes into the water and sandy or pebbly shorelines that accommodate families and casual swimmers. Boating opportunities abound on the reservoir's vast expanse, with water skiing, wakeboarding, and recreational boating taking advantage of the lake's calm waters and scenic surroundings. Fishing attracts anglers seeking walleye, rainbow trout, kokanee salmon, and smallmouth bass that thrive in the reservoir's ecosystem. Camping facilities throughout the recreation area provide options for extended stays, while picnic areas and shelters accommodate day visitors and group functions. The Inchelium-Gifford Ferry operates across the lake, offering a free crossing that connects the Colville Reservation with communities on the eastern shore while providing unique perspectives of the surrounding landscape. Hiking trails in the area explore the benchlands and canyons that rise above the reservoir, offering views of the lake and surrounding mountains. The combination of water-based recreation, cultural significance, and natural beauty makes Carson Beach a notable destination for those exploring the remote beauty of northeastern Washington's lake country.
