West Fork
The West Fork of the Mojave River originates near Lake Arrowhead in the San Bernardino Mountains, flowing through Cedar Springs before merging with Deep Creek near Hesperia. Historically, Cedar Springs was a ranching and logging community, but it was submerged in the 1970s when Silverwood Lake was created by the Cedar Springs Dam. Unlike the underground flow of the Mojave River in the desert, the West Fork has surface water in its upper reaches. It played a role in early settlements and supported wildlife before damming altered its course. Today, much of its former path lies beneath Silverwood Lake, serving as part of the California State Water Project. Like the rest of the Mojave River system, it belongs to a closed basin, meaning its water does not reach the ocean but instead dissipates into the Mojave Desert.
