And that is the last bit of surface flow in the Mojave River after coming off Deep Creek before it goes underground. Does not look very good for a beaver? No riparian corridor but Lawrence of Arabia amounts of sand. Until the river does something miraculous and resurfaces about 8 miles downstream at Mojave Narrows Regional Park where a confluence of geology forces the water back up. And discovering this amazing desert oasis are beavers from the nearby San Bernardino mountains where several translocations took place last century.
And they seem to like the desert.
Victorville looks like a veritable haven for beavers smack dab right in the middle of one of the most well known deserts in the world.
Look at that big body of water, the whole pond is about 750 feet long!!
You can actually back up and see the swath of riparian green - largely created by the beavers - contrasted sharply against the desert from outer space!! Beaver can attenuate waning surface flows and even more substantially increase subsurface flows.
A little bit after Victorville the river submerges underground again and the river become a wide sandy wash as pictured below.
So pretty cool little desert population of beaver. In the areas with surface flows the beaver have found them and greatly augmented the habitat for plants and wildlife, and deepened and widened the channel for more persistent year round flows and groundwater percolation. The Mojave River is a noted habitat for several endangered reptiles and amphibians - especially western pond turtles - and doubtless multitudes of bird species. Unfortunately the lone native fish - The Mojave Tui Chub - has more or less been pushed to the brink of extinction by its non - native introduced relative the Arroyo Chub. Interestingly the Mojave Tui Chub is an ice age holdover from when the Mojave river used to flow into a permanent lake so beaver would have likely benefited this fish as they prefer slow moving, lentic waters.
