<br />3. Mainstem flow, fine sediment inputs from tributaries (primarily the Little Colorado <br />and Paria Rivers), coarse sediment deposition by tributary debris flows and their <br />inter-relationships to other riverine resources. <br />4. Sediment outflow and its effects on Lake Mead resources. <br />5. Water quality parameters. <br />6. Synthesis of geomorphology and historic patterns of sediment resources. <br />7. Physical resources monitoring protocol evaluations. <br />3. The Biological Resources Program <br />Monitoring and research relating to biological resources is intended to refine and further <br />develop information about the structure and function of the Colorado River ecosystem in relation <br />to dam operations. Linkages between the biological resources program and the physical <br />resources program should be made to facilitate the understanding of the influence of abiotic <br />factors on biotic resources (e.g., discharge and sediment on fish habitat). <br /> <br />Monitoring and research efforts will address the following areas: <br />1. Aquatic food base. <br />2. Native and non-native fish populations. <br />3. Vegetation change with respect to species composition and area in the riparian <br />zones along the river. <br />4. Threatened and endangered species studies to address the population age <br />structure, diet analysis, and habitat requirements of listed species, including the <br />Kanab Ambersnail and Humpback Chub. <br />5. Avifauna monitoring that emphasizes the Southwestern Willow Flycatcher and <br />general riparian avifauna surveys with respect to habitat conditions, and population <br />censuses (e.g., riparian obligate species, resident non-obligate species, and migrant <br />species). <br /> <br />4. The Cultural Resources Program <br />Activities within the cultural resources program are intended to address stakeholder <br />objectives to: I) preserve in situ cultural resources; 2) consider Native American concerns for <br />resources; 3) design mitigative strategies when necessary; and 4) maximize information and <br />understanding of human occupation within the Colorado River ecosystem. <br /> <br />Program activities will address the following monitoring and research areas. <br />1. Synthesize existing monitoring and research data to provide information on <br />resource impacts and recommendations for management activities, and research <br />information and strategies. <br />2. Assess existing and develop additional data to predict inundation risk and related <br />sediment dynamics to assist in preservation of cultural resources above 45,000 cfs. <br />3. Assess existing and test local and reach-scale predictive models of geomorphic <br />processes that are related to archeological site erosion. <br /> <br />6 <br />
