Monitoring of water temperatures in backwater areas is also ongoing in <br />order to assess the thermal regime of these critical habitats. <br /> <br />20 <br /> <br />35,000 <br /> <br />""*"" Lees Ferry daily water temperature <br />18 -tr- Grand Canyon daily water temperature <br />- Lees Ferry daily discharge <br /> <br />8 <br /> <br /> <br />30,000 <br />25,000 ~ <br /> Q) <br /> Ol <br /> .... <br /> III <br /> ..c: <br /> 0 <br />20,000 1Il <br />'i5 <br /> .... <br /> Q) <br /> - <br /> III <br /> == <br />15,000 ~ <br />"iij <br /> 0 <br />10,000 <br /> <br />16 <br /> <br />Q: <br />~ <br />:J <br />- <br />~ <br />Q) <br />a. <br />E <br />Q) <br />- <br />.... <br />Q) <br />~ <br />~ <br />"iij <br />o <br /> <br />14 <br /> <br />12 <br /> <br />10 <br /> <br />6 <br /> <br />4 <br /> <br />2 <br /> <br />0 <br />0 0 0 0 0 0 0 0 0 0 <br />0 0 0 0 0 0 0 0 0 0 <br />0 0 0 0 0 0 0 0 0 0 <br />N N N N N N N N N N <br />. , , , , , , , , , <br />c: .0 lQ a. >- c: :; '" c- '0 <br />(1l Q) (1l :::l :::l Q) <br />--, LL ~ <( ~ --, --, <( en 0 <br /> <br />5,000 <br /> <br />o 0 <br />o 0 <br />o 0 <br />N N <br />, , <br />> 0 <br />o Q) <br />Z 0 <br /> <br />Figure 1.3. Daily water temperature data at Lees Ferry (mile 0) and Grand Canyon gages (mile <br />87) and daily flows at Lees Ferry during calendar year 2000. <br /> <br />Ongoing data analysis includes the assessment of spatial and temporal trends in the <br />monitored parameters (temperature, conductivity, dissolved oxygen, and pH). In the future, <br />analyses of these data will be integrated with the developing aquatic foodbase program, <br />particularly with respect to analyzing whole-stream metabolism using dissolved oxygen. <br />Protocols are in development for the transfer of collected data into the GCMRC Oracle database <br />in order to facilitate these integrated analyses. A protocol of annual data reporting (as USGS <br />Open-File Reports) is also being implemented in order to give stakeholders and other scientists <br />access to peer-reviewed data as quickly as possible. <br /> <br />Simulation Model Development and Application - Fine sediment transport model <br />development and application has been ongoing since 2003. Two models are under development. <br /> <br />GCMRC FY2006 Annual Work Plan (Draft February 15,2005) <br />
