Project Overview

Basics

CLEAN AND ABUNDANT WATER FOR HUMAN COMMUNITIES
Protect and Enhance Watersheds and Ecosystems that Provide Water Quality and Supply Benefits
Mattole Integrated Water Management Program
  • Address Climate Change and Extreme Event Effects, Impacts and Vulnerabilities
  • Conserve and Restore Salmonid Habitats and Ecosystems
  • Conserve, Enhance and Restore Watersheds and Ecosystems that Support Biological Diversity
  • Ensure that Disadvantaged and Underrepresented Communities Benefit from Initiatives
  • Ensure Water Supply Reliability and Quality
  • Respect Local Autonomy and Local Knowledge in NCRP Planning and Implementation
NCRP IRWM Prop 50 R1 (SWRCB)
Completed
The Mattole Integrated Water Management Program integrates basin-wide efforts to meet water supply, water quality and salmonid habitat goals for the coastal Mattole River watershed. The Program will yield increased water supply in drought-prone areas, augmented summertime streamflows in critical salmon-bearing reaches, sediment reduction to meet TMDL and NCRWQCB Basin Plan goals, and habitat improvements. A suit of effectiveness monitoring components will determine project performance and future management measures. By implementing these projects through an existing and robust watershed partnership, the project will address multiple management goals for habitat and water supply.

Project Attributes

General Information

Project Description Narrative (1,000 character limit)
The goals of this project are to prevent sediment from entering Class I watercourses, to plant trees in riparian canopy-limited streams, to install large-scale water storage, remove noxious weeds,collect native grass, shrub, and tree seed, install willow fence, propagate plants and monitor stream turbidity levels and aquatic habitat to assess restoration effectiveness and watershed condition. The Mattole River watershed is critical spawning and rearing grounds for several state and federally listed salmonid species.
