<br />u02151 <br /> <br />9 <br /> <br />The synthesis of existing knowledge associated with Lake Powell and the riverine <br /> <br />corridor's resources after Dam construction, as well as relevant data and information from other <br /> <br />regulated and unregulated western riverine corridors, that are of similar character and structure to . <br /> <br />Lake Powell and the Colorado River ecosystem will be completed in the fIrst two to three years <br /> <br />of the Strategic Plan. These syntheses are addressed in the individual resource program areas. <br /> <br />Completion of these syntheses will provide an important tool for organizing our <br /> <br />understanding of this riverine ecosystem and the impacts of flow regulation. Anticipated end <br /> <br />products include a more integrated data assessment and interpretation of critical alternatives <br /> <br />associated with resources of concern, and a major comprehensive transfer of information to <br /> <br />stakehOlders from GCMRC, regarding the potential impacts of alternative operating criteria on <br /> <br />riverine ecosystems and associated resources. <br /> <br />The Physical Resources Program <br /> <br />Hydrology and sediment are the two primary resources of concern in the physical <br /> <br />resources area. Impacts from Glen Canyon Dam operations on these physical resources also <br /> <br />extend to other resources, such as biological and cultural. For the most part, planned FY 99 <br /> <br />monitoring and research efforts were started in the FY 98 program and will continue to focus on <br /> <br />four areas of impact from dam operations as follows: <br /> <br />1. Influence on mainstem flows. <br /> <br />2. Sediment balance and geomorphic processes, including those related to active <br />sandbars used as camping areas and terrestrial and aquatic habitats, and pre-dam river <br />terrace deposits containing cultural resources. <br /> <br />.
