Brush clearing for several thousand acres of the San Angelo State Park is expected to begin next spring thanks to a new federal grant. The grant money of more than 800-thousand dollars is designated for the eco-system around O.C. Fisher reservoir which is in many places, choked with salt cedar and other trees and plants that consume large amounts of water. Hydrologists say they expect some of the springs and creeks in the area to re-gain flow after the clearing. They also predict the lake level to rise. Willow spraying will be begin in the spring along with mesquite removal and Aerial spraying will begin next Fall.
