Since 1980, riparian management programs have increased on federal lands within Modoc County. These programs have been designed to correct problems associated with past grazing and logging practices. The major riparian habitat problems included: Widening/braiding of stream channels; depleted or lowered water tables and reduced cover from overhanging backs and woody vegetation. These resulted in high water temperatures, increased siltation, lack of pools, intermittent stream flows, and the elimination of overhanging bank cover, instream structure and woody vegetation. Riparian improvement efforts have centered on habitat for trout and Modoc suckers. These improvements have included: control and management of livestock grazing; installation of instream and back stabilization structures; and establishment of woody vegetation. Riparian management on private lands has been limited by a lack of funding. One example of private efforts is the work on Canyon Creek through an Agricultural Stabilization and Conservation Service cost share program. This creek was improved by grade and bank stabilization structures, boulder and log weir placement, and fencing to control livestock grazing. It is too early to draw specific conclusions from the projects, but indications are that livestock management must be part of any riparian improvement project and must be designed to meet stated riparian objectives.
