US Army Corps of Engineers and EPA deem the Los Angeles River a “Traditional Navigable Waterway”

This new reclassification guarantees LA River federal protections under the Clean Water Act. Kayaking and other recreation activities are allowed within two zones, one in the Sepulveda Basin and the other in Elysian Valley, throughout the season (the end of May through the end of September). The LA River flows from its origins at the confluence of Arroyo Calabasas and Bell Creek to San Pedro Bay at the Pacific Ocean, approximately 51 miles.
