<br />00173~ <br /> <br />11 <br /> <br />information collected since 1965, representing the entire water quality history of Lake Powell. <br />The consolidation and management of these data make it possible to evaluate the information <br />collected from this long-term effort and make changes in sample collection to achieve a more <br />efficient program. Revisions in major ion and nutrient sampling, plankton sampling, and inflow <br />monitoring are expected during FY2006-2007. Monthly and quarterly provisional data from <br />monitoring trips are posted on the GCMRC website and open file reports for each water year are <br />published. The latter was instituted for WY2003. <br />The GCMRC receives funding for the Lake Powell Water Quality Monitoring Program from <br />Bureau of Reclamation Operation and Maintenance funds, based on an agreement with the Technical <br />Work Group. Adaptive Management Program funds are not used directly for Lake Powell <br />monitoring. The Bureau provides additional support for model development and technical field <br />assistance. Additionally, reclamation provides laboratory analytical services through a service <br />agreement, eliminating the need for GCMRC to contract directly for these services and reducing its <br />direct funding to GCMRC. <br /> <br />Inteerated Quality-or-Water Downstream Component <br /> <br />The Integrated Quality-of-Water Project (IQWP) has two major downstream components. <br />The first component is focused on monitoring and modeling the mass-balance of fine sediment in <br />the CRE. Monitoring of fine sediment is important because 1) sand typically provides the <br />material that accumulates in side-channel eddies and creates sandbars that provide backwater <br />habitat areas for native fish and recreational campsites for river runners, and 2) very fine <br />sediment creates turbidity that was ubiquitous in the pre-dam era and has a significant effect on <br />many ecological functions. The second component of IQWP downstream is focused on <br />characterizing other water quality components of the ecosystem, such as water temperature, <br />oxygen, nutrients, and carbon. This component of the program will have a strong linkage to the <br />newly developing aquatic foodbase initiative. <br /> <br />Fine-Sediment Mass Balance - A return to daily monitoring of the fine-sediment mass <br />balance (i.e. input minus export) in the CRE began in August of 1999. Since then, the project has <br />made significant advancements in the monitoring of fine sediment transport through the use of <br />emerging technologies such as laser diffraction and acoustic backscatter. Results of sand-transport <br />mass balance calculations for the period of fall 1999 through September 2000, show that sand loads <br /> <br />GCMRC FY2006 Annual Work Plan (Draft February 15,2005) <br />
