<br />001695 <br /> <br />Wetland Mitigation <br /> <br />A- 6 <br /> <br /> <br />. Landowner access permission; <br />. Landowner plans for future development (e.g. areas proposed for gravel mining <br />or other instream activities would be poor choices); <br />. Wetland type and extent; and <br />. Predicted impact (e.g. predicted gain or loss based upon completed studies). <br />. Proximity to indirect impact mitigation sites. <br /> <br />The goal will be to obtain results from a varied set of circumstances that, together, are <br />representative of overall project effects. <br /> <br />Sponsors propose that monitoring locations be identified and submitted to the Corps and <br />Reclamation at least 120 days before the end of the last growing season before <br />commencement of project operationsl. During this last (pre-project) growing season, <br />after receipt of approval from the Corps and Reclamation, Sponsors will survey and set <br />targets at each of the monitoring sites. A pre-project, baseline set of data will then be <br />obtained. <br /> <br />Once project operation has commenced, the monitoring transects will be revisited and <br />observed annually, during the growing season. Sponsors propose that such observations <br />be made in the early fall, when vegetated bands will be at their maximum annual extent. <br />This time frame will also correspond with relatively low flows, making river access safest <br />for biologists. <br /> <br />Groundwater monitoring wells would be established at the monitoring sites to ensure that <br />sufficient hydrology was present during the growing season to maintain and extend the <br />limits of wetlantfriparian vegetation. <br /> <br />A.2.4.3 Hydrologic recordkeeping <br /> <br />Hydrology is an important variable in the development and preservation of wetlands. <br />The Sponsors will maintain daily records of river flow at various locations between Delta <br />and Montrose (e.g. tailrace, USGS Olathe gage, East Canal Headgate, and USGS Delta <br />gage). These data (together with groundwater monitoring wells discussed above) will be <br />used to establish project- vs. non-project related hydrologic effects, and ultimately <br />establish trends and other statistical parameters that can be used in evaluating <br />survivorship and recruitment of wetland and riparian vegetation. <br /> <br />A.2.5 <br /> <br />Analysis and Reporting <br /> <br />Alternatively, locations could be identified prior to construction, in the Final Wetlands Mitigation Plan. <br />The Applicants. however, would prefer the additional time to firmly establish private access and <br />related issues. <br /> <br />AB Lateral Hydropower Project <br /> <br />July 2000 <br /> <br />
