Mid-Coast Monitoring Program

Spawning Survey and Aquatic Habitat Monitoring

Our Goal is to Document the Environmental Responses to Conservation Practices through Species Monitoring to Evaluate their Effectiveness to the Local Ecosystem.
Steelhead Population Trends
Salmon Population Trends
What do we monitor?
  • Stream Restoration Projects
  • Fish Passage Improvement Projects
  • Fish Usage in Project Areas

What methods do we use? 
  • Pre & Post Project Aquatic Inventory (Habitat)
  • Direct On-ground Observations
  • Adult Spawning Ground Surveys for salmonids

Aquatic Habitat Inventory Process 
  • Pre and post project Aquatic Habitat Inventory following ODFW protocols
  • Qualifying & quantifying: Habitat Units, Stream Gradient, Substrate, Unit Length & Wetted Width, Channel Morphology, Channel Metrics, % Shade, % Undercuts, % Active Erosion, Fish and Wildlife Use, Land Use and Ownership
  • Digitization, Quality Control, and Submission to ODFW for Analysis
  • Post Project Inventory with Analysis

Habitat: Determining Results 
  • Set Restoration Goals Based on Pre Project Habitat Conditions
  • Bed Load Accumulation Vs Entrenchment
  • Gravel Retention Vs Scouring
  • Floodplain interaction & Terrace Building
  • Habitat Complexity and Large Wood Recruitment
  • Comparison of Analysis of Pre & Post Inventories
  • Comparison of Queries on Raw Data of Pre & Post Inventories

Habitat Reporting Process 
  • Supply Mid Coast Watersheds Council and/or Other Partners with access to Pre & Post Project Analysis and Pre & Post Raw Data for Inclusion in Project Final Reports where appropriate
  • Include Project Monitoring results in Final Reports to OWEB
  • Data is available upon request - Contact us!

Adult Spawning Surveys 
Spawning surveys are conducted for Chinook, coho, and chum salmon, steelhead, and lamprey eels. All Surveys are coordinated with ODFW Oregon Adult Salmonid Inventory & Sampling Project for consistency. Data collected include numbers of each species and redds. Bio-information includes length, sex, scale samples (to determine age), collect snouts on tagged (hatchery) fish, DNA (when requested), and other basin specific projects. The surveys we do are:
  • Spring Chinook Float Surveys​​
  • Fall Chinook Walking Surveys
  • Fall Coho Walking Surveys
  • Winter Steelhead Float Surveys
  • Winter Steelhead Walking Surveys

Spring Chinook Float Surveys – Alsea & Siletz Rivers ​
  • ​Alsea River Surveys​:
    • ​Honeygrove Bridge to Schoolhouse Creek
    • South Fork Alsea to Schoolhouse Creek
    • Schoolhouse Creek to Salmonberry Park
    • Salmonberry Park to Digger Creek
    • Digger Creek to Big Riffle Ranch Road
  • Siletz River Surveys: 
    • Logsden to Twin Bridges
    • Twin Bridges to Illahee Park
    • Ojalla Bridge to Morgan Park

Coho, Chinook, Chum & Steelhead Walking Survey Results
  • Many of these surveys have had LWD Placement
  • Direct On Ground Observations & Documentation of Fish Use & Stream Changes Throughout the Winter & Spring
  • Steelhead Surveys Results
    • Alsea River Basin
    • Ocean Outfalls
    • Salmon River Basin
    • Siletz River Basin
    • Yachats River Basin
