<br />TASK NO: 11 <br /> <br />Aquatic Resources Studies <br /> <br />SUBTASK NO: Ilh <br /> <br />Mitigation Measures <br /> <br />PURPOSE: <br /> <br />Subtask llh activities will provide insight into mitigation <br />measures which may be necessary for stream resource effects. <br /> <br />APPROACH: <br /> <br />Mitigation may be required for stream resources lost to <br />inundation. Mitigation for stream resources lost to inundation in <br />the main stem impoundment area will be determined through comparison <br />of HQI units pre- and with-project. Agency guidelines on <br />mitigation to adjust for losses in stream and gains in lake <br />resources will be obtained. Typically, net stream resource losses <br />are mitigated through purchases of stream access easements <br />elsewhere, or through such measures as fish hatchery development. <br />Mitigation for any net losses in stream habitat, if they occur, are <br />usually sought through changes in the project-related streamflow <br />regime. Cost and scheduling aspects of mitigation measures will be <br />addressed. <br /> <br />OUTPUT: <br /> <br />Preliminary mitigation proposals and their associated cost and <br />schedule implications will be provided as a chapter in the Task 11 <br />report. <br /> <br />6162a <br /> <br />11-18 <br />
