"-;'C"0 614 Grand Canyon National Park Natural Resource Linkages to the Adaptive Management Program June 15, 2005 Earth Science and HvdroloQv Title of Project: Routine sampling of 20 + tributaries along the river corridor near the confluence with the Colorado River. Objectives of Project: Field Parameters (base funded) with occasional Lab processing as funding/partnership opportunities permit including bacteria, isotopes, nutrients, metals and radionuclides. New sites have been visited over the years to complete inventory efforts of WQ at seeps and springs along the corridor. Geographic Area of Project: River Corridor Sponsor(s) of Project: GRCA Approximate Funding and Sources: Base funded with contributions from other sources as available ($8,000.00)/yr. Title of Project: Long term Discharge Monitoring at S. Rim Seeps and Springs Objectives of Project: Maintain stream gauges at 3 tributaries and collect discharge (and other water quality data) at 10 tributaries, 8x per year. Geographic Area of Project: South Rim Redwall-Muav Aquifer Springs Sponsor(s) of Project: GRCA Approximate Funding and Sources: Base and Fee-Demo ($50,000.00). Title of Project: Complete and publish results of Water Chemistry Study from 30 plus sites, in cooperation with USGS. Sample additional wells in Tusayan and Williams areas as funded; Objectives of Project: Ground Water Flowpath Studies Geographic Area of Project: South Rim Redwall-Muav Aquifer Springs and wells Sponsor(s) of Project: GRCA Approximate Funding and Sources: Fee Demo, NPS-WRD, WAQAM (NPS, USGS Partnership Program) ($200,000.00) Title of Project: Conclude Geologic Mapping funded by GRCA/WASO-Water Resources Division in cooperation with USGS (looking at Ground Water flow pathways in Grand Canyon); Objectives of Project: To understand Hydrogeology/Ground Water Flow Pathways Geographic Area of Project: Regional, Coconono Plateau and beyond. Sponsor(s) of Project: GRCA, NPS-WRD Approximate Funding and Sources: NPS-WRD ($200K). Title of Project: Conclude pilot project: Grand Canyon Springs/Ecosystems Coupled Models (NAU, USGS-BRD, NPS cooperators) Objectives of Project: To understand Hydrogeology/Ground Water (GW) Flow Pathways and the Effects of Modeled GW Decreases to the Ecosystem.
