<br />e <br /> <br />. <br /> <br />. <br /> <br />IV. Past Performance on this or similar projects: <br /> <br />During the past 6 years. the concept of a channel monitoring interdisciplinary team <br />has proven to be successful in shedding new insight on top priority issues. This <br />approach has resulted in a considerable amount of information being collected and <br />analyzed at a relatively low cost to the Program. The approach has taken advantage <br />of previous efforts and has capitalized on cooperative efforts, available data, and <br />expertise within the Recovery Program to provide information that can be used to <br />develop flow recommendations and design habitat improvement projects. <br /> <br />V. Study Area: <br /> <br />VII. <br /> <br />Colorado and Green Rivers, and areas within this system, the sites identified in the <br />Pilot Study Survey. and others that may be identified in the future. <br /> <br />VI. <br /> <br />Study Method/Approach: <br /> <br />Each year, one or two important sites are selected for baseline or follow up <br />monitoring based on annual program guidance and priorities, Cross sections will be <br />established or remeasured to collect data on baseline or current conditions. Over a <br />period of years, a rotation schedule will be established so that monitoring sites will <br />be resurveyed every 5 years. To the extent possible, the monitoring work is coordinated <br />with other research efforts. and trips will be planned to take advantage of other field efforts, <br /> <br />Efforts to secure old cross section data, photographs, and the establishment of an <br />archiving system will continue. A report and maps will be developed documenting <br />the results of each year's monitoring effort. This information will be incorporated <br />into a data base for analysis and for development of flow recommendations. <br /> <br />Task Description: <br /> <br />Yampa River Oeerlodge Park Area: Tasks will include securing and reviewing field <br />books and field notes produced in 1981 and 1982 by Jim O'Brien for the National <br />Park Service for work accomplished at Oeerlodge Park and in the Yampa River. A <br />sole source contract will be negotiated with Jim 0' Brien to help locate and resurvey <br />as many of the cross sections as possible in the Oeerlodge Park area. The cross <br />section will be analyzed to determine changes in the past 15 years. and to serve as <br />a baseline to identify future channel morphological changes. These cross sections <br />will be surveyed with permanent endpoints that will be located using a GPS system. <br />Several new cross sections may be established at apparent incision points. transition <br />zones, and locations that represent the variability of the alluvial channel. Bed <br />samples will be coflected where potential for channel change is identified. Any <br />changes will be evaluated in relationship to an increase or decrease in the Little Snake <br />sediment load since the early 1980's. <br /> <br />Establish Little Snake Cross Section Monitoring System. Four to five cross sections <br />will be established in the lower 5 mile section of the Little Snake River. The cross <br />sections will be surveyed with 'permanent endpoints that will be located using a GPS <br />system. Channel geometry, bed material slope, and general morphology will be <br />described in an annual Channel Monitoring report. <br /> <br />The information gained from the monitoring activity will be used to support the <br />development/refinement of flow recommendations for the Yampa and Little Snake <br /> <br />2 <br />
