Jeffrey Lake is relatively secluded among the rugged terrain through which the Supply Canal flows, but it has been developed for recreational uses.  Located five miles south of Brady, the lake covers 575 surface acres and has 25 miles of shoreline.  There are 135 homes and cabins at the lake. The property on the west side of the lake is privately owned pasture land

The lake attracts a wide variety of wildlife, including great blue herons, pelicans, several species of waterfowl, bald eagles, deer and many species of birds, mammals and fish.
