Redband trout (Onchorhynchus mykiss gairdneri)
Hangman Creek Fisheries EnhancementBPA Project 2001-032-00
&Hangman Restoration Project: Wildlife
BPA Project 2001-033-00
ObjectivesDecrease rate of floodplain
groundwater depletion through the dry season
Increase baseflows in Project Area streams
Involve students in the process
2001-033 Project Objectives
Project Area Priority Habitats
Fish Bearing Reaches
Potential Connecting Reaches
Fisheries Priority Habitats (2001-032-00)
Wildlife Priority Habitats (2001-033-00)
Hydrologic Priority Area:Low Gradient Floodplain
Sheep Creek Realignment
2001-032 Project Objectives Improve Stream Habitats
Increase frequency of over-bank flows to insure stream/riparian connection
Treat streams to meet wood loading criteria Increase Canopy cover in tributaries and
mainstem Decrease stream temperature
Track Trend and Status of Redband Trout Demographics & Pop Structure
Evaluate Effectiveness of Restoration actions

Initial Restoration DirectivesPrioritization Plan
Northern Watershed (Rock Creek) eliminated based on cumulative impacts
Conserve core fish-bearing reaches Restore Connective Habitat Remove migration barriers IFIM Report directives
Increase Canopy on mainstem habitats
Increase pool depths in tributaries
Initial Restoration: Riparian & LWD
X-Vein at Indian Creek
Restoration Proposed: Herrera
Subcontract
- LWD: Heavy Equipment- LWD: By Hand- Riparian Enhancement- Beaver Clippings- Fish Ladders installed
RME Elements Pit tagging program to accompany
summer electroshocking Summer abundance estimates Continuous Temperature Monitoring Discharge Habitat Surveys.
Conclusions Restoration will closely follow a clear
progression of priority habitats Beaver will be used as a cost effective
means to agrade channels Riparian enhancements will follow
channel work Long term goals of the project are met
by efforts of the Project 2001-033 Short term goals are met by efforts of
