City-sanctioned canoe and kayak excursions along a placid, 3-mile stretch of the Los Angeles River in the San Fernando Valley’s Sepulveda Basin are expected to start in July. The three-hour journeys will be offered on weekends at a cost of $50 per person. Participants will be chaperoned by a Los Angeles Conservation Corps naturalist. The goals of the pilot program include raising awareness of the river and its history. The images in the gallery above were taken in 2010 shortly after the U.S. Environmental Protection Agency designated the river a “traditional navigable waterway.” George Wolfe and Joe Linton walk their vessels through the shallows as they head down the L.A. River during a recent trip after the river's waters were declared a traditional navigable waterway. Joe Linton paddles through a picturesque section of the L.A. River which is more often associated with concrete than lush greenery. Kayakers make their way down the L.A. River near Atwater Village.
