0016U1 Alternatives. Including Proposed Action 2-31 The Sponsors have initially budgeted $70,000 per year to fund Uncompahgre River monitoring and maintenance activities. This includes efforts devoted to monitoring and managing wetlands, riparian vegetation, channel stability and the protection sites. It does not include the additional security that will be posted to protect against unforeseen events (See Section 2.4.6.5), The budget will be adjusted on an annual basis, as experience is gained, and requirements for monitoring change under the approved plans. Should this budget be insufficient for whatever reason, then additional funds would be available from project revenues. 2.4.6.1 Bank Stabilization Monitoring The Sponsors would implement a long-term monitoring and maintenance program in conjunction with the bank stabilization activities. This comprehensive program would extend through the 40-year term of the lease of power privilege. The primary goals of this portion of the Sponsors' monitoring and maintenance program are to ensure that the proposed stabilization measures are and remain sufficient to protect against project- induced erosion, and to identify future, additional stabilization needs. The Sponsors' 10ng-tetID monitoring and maintenance program would include: . observation and identification of problem areas documentation of bank erosion and changes to the river observation and monitoring of the stabilization sites remediation measures identification of sites needing future stabilization . . . . The selected stabilization sites would be protected in advance of operations. After the start of operations, they would be inspected periodically to determine whether the protection measures are effective. The monitoring would include aerial and ground-level observations and photography, together with detailed record-keeping of project and non- project flows. In the first five years, the aerial monitoring would take place semiannually; after that, the monitoring frequency would be reviewed and adjusted based on experience. In addition, a field inspection of all sites would be conducted after any flood event8 on the Uncompahgre River. Landowners typically observe their banks frequently (monthly, weekly, or even daily). If there are indications that the stabilization is ineffective, the landowners could request supplemental inspections by the Sponsors. The need for maintenance would be indicated, for example, by loss of rock to scour holes, channel movement that threatens to flank protection, and failure of vegetation to grow through revetment. Unless a major flood caused significant damage, the Sponsors' 8 An Uncompahgre River flood event would be defined initially as approximately 1,900 cfs or greater at the Selig Canal (Sigma et a!., 1996). ;;; AS Lateral Hydropower Project JUly 2000 "~ .; ~ . .-", 1 .:'\ , ,., ";,j:,-"",-,~~ lL,
