FHMP Overview

This overview provides information on the goals, decision rules, and targets of the Cowlitz Fish Habitat Management Program. It covers the conservation and harvest goals, annual decision-making process, and specific rules for Fall Chinook, Coho, and Steelhead populations in the Lower Cowlitz River.

  1. FHMP Overview Program Goals and Decision Rules May 6, 2016

  2. Cowlitz FHMP Settlement Goals • Protect and restore natural-origin fish populations • Provide opportunities for recreational harvest

  3. Annual Decision Making Process • Review Status and Trends data and Key Assumptions • Review Conservation and Harvest Goals • Review and Apply Decision Rules • Conservation and Harvest-driven Rules • Conform with 650,000 Pound Production Cap • Apply Crediting Rule • Determine quantity and size of releases

  4. Conservation Goals(based on the Recovery Plan)

  5. Current Biological Targets

  6. How HSRG Standards Apply by Designation and Phase

  7. Harvest Goals

  8. Decision Rules • Purpose of Decision Rules: • Calculate annual Management targets for number of releases, pNOB, harvest, etc. based on run forecast • In the long-term, help achieve conservation and harvest goals for each population • Brief overview of Decision Rules for: • LC Fall Chinook • LC Coho (detailed overview in the next presentation) • Steelhead

  9. Lower Cowlitz Fall Chinook • Hatchery program size • 1.5 to 3.5 million depending on NOR run size • Integrated program is always 1.1 million • Segregated program ranges from 400,000 to 2.4 million • If NOR < min value => 400,000 seg releases • If NOR > max value => 2.4 million releases • If NOR between min and max: release number is between 400K and 2.4 million

  10. Lower Cowlitz Fall Chinook • Calculations are based on Key Assumptions and Biological Targets • NOR range (min and max) is the number of NORs needed to meet the pHOS target of 20% given: • Min (or max) number of integrated and segregated releases • Assumptions about SAR, stray rate, and exploitation rate for HORs, terminal NOR harvest rate, pNOB of 20%, etc.

  11. Lower Cowlitz Coho • Hatchery program size • 1.2 to 2.4 million depending on NOR run size • Segregated program ranges from 1.2 to 2.4 million • If NOR < min value => 1.2 releases • If NOR > max value => 2.4 million releases • If NOR between min and max: release number is between 1.2 and 2.4 million • Upper Cowlitz program always releases 978,000 smolts

  12. Lower Cowlitz Coho • Calculations are based on Key Assumptions and Biological Targets • NOR range (min and max) is the number of NORs needed to meet the pHOS target of 5% given: • Min (or max) number of segregated Lower Cowlitz releases plus the baseline (978,000) number of UC releases • Assumptions about SAR, stray rate, and exploitation rate for HORs, terminal NOR harvest rate, pNOB, etc.

  13. Lower Cowlitz Steelhead • Hatchery program size depends on: • NOR run size • Size of segregated summer steelhead program • Total and segregated pHOS • Key Assumptions about SAR, RRS, harvest, stray rate, and weir effectiveness

  14. Lower Cowlitz Steelhead • Due to the low assumed stray rate, pHOS is expected to stay well within the 30% standard for a full program:
