<br />Lf <br /> <br />M~. Eddie Kochman <br /> <br />4 <br /> <br />removed. This would avoid the possibility of the pond and river communicating <br />due to overfilling or malfunctions with the flapper gate as occurred in 1993. <br />Since overfilling by pumping should result in only a small volume of water <br />spilled, that spillage could be directed to the manicured lawn area north of <br />the pond. <br /> <br />If the pond is determined to be within the 40-year floodplain, the Service <br />recommends the pond be stocked with salmonids and the higher ponds in the park <br />be maintained as warm-water fisheries. (Note: In this scenario, removal of <br />the flapper gate would not be necessary.) Raising the level of the roadbed <br />berm to place the pond outside the 40-year floodplain may also be an option. <br /> <br />Parachute Pond <br /> <br />The hydrology of this pond is not well defined at this time. A slough is <br />located along the northern shore of Parachute Pond and is separated from the <br />pond by the narrow shelf of pond shoreline. This slough discharges directly <br />into the river near the western end of the pond. Only a slight rise in the <br />water surface elevation of the pond is required to allow the pond and the <br />slough to be connected. The Service recommends additional information on the <br />relationship of Parachute Pond and this slough be obtained. <br /> <br />The pond is also adjacent to a large secondary channel of the Colorado River. <br />Some crude riprap had been placed along the bank to reduce erosion. The <br />riverbank is lowest along the western end of the pond and connection with the <br />river at high flows would occur here first. Determination of the 40-year <br />floodplain will be extremely important for this site. The Service will <br />support the LMP for Parachute Pond with resolution of the floodplain elevation <br />and escapement questions. <br /> <br />Rifle 1-70 Pond <br /> <br />Provided the Rifle 1-70 Pond is outside the 40-year floodplain, the Service <br />would not be opposed to implementation of the LMP for this site. Should the <br />Rifle 1-70 Pond be within the 40-year floodplain, the Service recommends <br />continued stocking with salmonids only. <br /> <br />Thirty Road Pond <br /> <br />The outlet structure at this site is an un screened pipe discharging into a <br />backwater of the Colorado River. The pond appears to be above the 40-year <br />floodplain and protected by a well-engineered dike. However, the outlet <br />structure needs to be screened to prevent escapement of larval and larger fish <br />to the backwater. A small self-cleansing rotary screen with suitable mesh <br />size would easily control escapement'()'f'-nonnative fishes at relatively low <br />cost. With implementation of this modification, the LMP for Thirty Road Pond <br />would be supported by the Service. <br /> <br />McPhee Reservoir <br /> <br />The Service finds that additional information is required for proper <br />evaluation of the McPhee Reservoir LMP. The two spill events that have <br />
