coyote creek and watershed stewardship objectives are consistent
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
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
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

summary
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
