"In 1972 the Corps of Engineers dammed Martis Creek, creating Martis Creek Lake, a reservoir that at full capacity holds 20,400 acre-feet of water with a surface area of 770 acres. Across Highway 267 to the south, in the open plain of Martis Valley adjacent to the Northstar-at-Tahoe resort community, the Corps manages a wildlife area that has a fine network of trails suitable for hikers, joggers, dog walkers, and amateur biologists.
With so many connecting paths, trail users can easily customize their trips. The trip described below is a 4-mile loop around the fringe of the wildlife area. Wildlife sightings may include mule deer, coyote, golden-mantled ground squirrel, pocket mouse, chipmunk, and raccoon. Birds common to the area include red-tailed hawk, killdeer, mountain quail, and the Canada goose."
