<br />. <br /> <br />Wetland Habttat ManaQement Action #5 <br /> <br />. <br /> <br />Create small ponds in the mitigation area with a Iota] surface area acreage of 8 acres by providing <br />adequate surface irrigation on the mitigation area to maintain standing water in imermittent oxbow <br />channels that are present on the area <br /> <br />Responsible Agency: BLM <br />Cooperating Parties/Agencies: CDOW, USF'NS, COE, EPA <br /> <br />. <br /> <br />Over a acres of existing oxbow channels and old stream meanders exist on the lower Muddy Creek <br />mitigation area These channels generally flood during runoff in late Mayor earty June. As water <br />levels in Muddy Creek recede in late June and early July, the majority of these ponds drain or dry up <br />from evaporation and are dry for the remainder of the summer and fall. Irrigation water supplied to the <br />lower Muddy Creek mitigation area via surface irrigation as outlined in wetland habitat management <br />action #2 will effectively maintain standing water in these ephemeral oxbows, creating pond habitat <br />identical to habitat inundated by the proposed reservoir. Since these oxbow ponds will not exist <br />without water supplied by the proposed management action, loss of pond habitat incurred by the <br />proposed project will be fully mitigated. <br /> <br />. <br /> <br />No costs specific to this management action are anticipated. <br /> <br />. <br /> <br />Wetland Habitat Manaaement Action #6 <br /> <br />Establish and implement a monitoring program to ensure successful implementation of wetland habitat <br />management actions 1 through 5. <br /> <br />t <br /> <br />Responsible Agency: BLM <br />Cooperating Parties/Agencies: CDOW, USF'NS, COE, River District <br /> <br />t <br /> <br />A detailed program designed to monitor changes in wildlife habitat on the mitigation area is essential <br />to ensure full mitigation of impacts to wetland wildlife habitat. locations of study plots and photo <br />points are presented in Map 5. Proposed tasks included in a monitoring program will be as follows: <br /> <br />I <br /> <br />1. During the first year, following implementation of the project and once the irrigation systems are in <br />place and operating, visual inspections of all irrigation facilities will be made bimonthly during the <br />operating period to ensure that water is being adequately delivered to target areas. During this time <br />the inspector will make necessary adjustments on control vaNes or head gates in order to maximize <br />coverage of areas targeted for irrigation and maximize efficiency of water use. The inspector will also <br />be responsible for noting problems with the systems and making recommendations for adjustments or <br />additions to the system such as adding additional outlet valves or headgates, digging lateral ditches <br />or contour trenches, or adding other improvements to the system. <br /> <br />I <br /> <br />2. During the second and third years, following implementation of the project, visual inspections of all <br />irrigation facilities will be made monthly for the same purposes as described above. <br /> <br />3. Following three years of operation, all major adjustments to the irrigation system should be complete <br />and settings on valves and gates referenced so they can be easily set. Starting on the fourth year of <br />operation the irrigation systems will be inspected immediately after the start of operation in the late <br />spring. then once at a point approximately hatfway into the operating schedule for the year, and again <br /> <br />20 <br />
