Coyote Creek Watershed Integrated Pilot Assessment Santa Clara Valley Urban Runoff Pollution Prevention Program
Watershed Stewardship Project • Watershed Assessment Methodology • Stream Ecosystem Indicators • Hydromodification Plan • Other Indicator Reports Water Resources Protection Collaborative SCVURPPP Monitoring & Assessment • SCVWD • Ends Policies, • Natural Flood • Protection • Program
Coyote Creek and Watershed Stewardship Objectives are consistent • Identify conditions and issues that affect watershed health using Indicators • Identify appropriate management actions • Provide direction for long-term monitoring program • Identify appropriate monitoring locations
Assessment Approach • Integrated 2 Assessment Approaches • Hydrogeomorphic Model (HGM), USACE • Multimetric Indices of Biological Integrity, EPA • Evaluated 5 Stream Ecosystem Functions/Indicators • Hydrologic Processes and Channel Dynamics • Riparian Habitat Condition • Aquatic Habitat Condition • Landscape-Level Aquatic Habitat Connectivity • Aquatic Faunal Community
Evaluating Stream Functions/Indicators • Existing Condition • Used existing data • Developed models that rank existing values relative to reference standard conditions or best existing conditions • Future Condition • Positive/negative impacts of planned projects • Potential Condition • Unplanned pragmatic and strategic management actions
Ecosystem health indicator Historic conditions (with uncertainty) Un recoverable damage Restoration potential Socio economic choices Current conditions 1800 1850 1900 1950 2000 2050 2100 Time Slide Developed by Watershed Stewardship Project Team
Results Future, Potential Condition: Coyote Reach 9 • Future: expect little change • Potential: • Improve through Management Actions • Stakeholder Process 0 = Low = Low/Medium = Medium = Medium/High = High ND = No Data
Potential Management Actions to Improve Watershed Health:Coyote Reach 9
Potential Monitoring Actions to address Data Gaps:Coyote Reach 9
Summary • Method for Assessing Watershed Health • Quantitative, Repeatable Indicators • Mechanisms for recommending management changes and prioritizing restoration efforts • Supports SCVWD Ends Policies, and Natural Flood Protection Project Guidance (NFP) • Next Steps: Develop/Refine Methodology to • Better serve NFP and Ends Policies • Correspond to methods proposed by SCVURPPP and Water Resources Protection Collaborative
