3. The Malheur Subbasin
4. Key Subbasin Facts 40 + Irrigation Dams – Impoundments & Irrigation Projects
Primary Land Uses – Agricultural Production and Processing
95% of Watershed is listed under 303d list
Existing Plans Pertaining to Subbasin
- Oregon Plan
- Malheur River Management Plan (ODFW 1990)
- ICBEMP (BLM/USFS)
- Vale/Burns District Resource Management Plan (Draft 2002)
- Malheur River Wild & Scenic Management Plan
- North Fork Malheur River Wild and Scenic Management Plan
- Malheur Basin Action Plan (MOWC)
- Bull Trout Recovery Plan (USFWS, Draft)
- Logan Valley Wildlife Mitigation Plan (BPT, Draft out for review)
- Malheur River Wildlife Mitigation Plan (BPT, Draft April 2002)
5. Fish and Wildlife Needs Within the Malheur Subbasin Critical limiting factors for fish include:
- anadromous and resident fish habitat,
- migration routes and connectivity of
isolated populations of bull trout and
redband trout,
- water quality,
- minimum winter flows below reservoirs.
6. Critical limiting factors for wildlife include:
- the lack of natural disturbance in
riparian, meadow, and upland communities,
- excessive grazing of certain sensitive areas by
livestock,
- limited bighorn sheep range,
- reduction of native shrub and grass cover in
deer and elk winter range,
- expansion of noxious weeds.
7. Mitigation History within the Subbasin Pre-mitigation
- lack of coordination between agencies and
private interests.
Current successes resulting from mitigation efforts
- cooperative relationships established or
enhanced.
8. Partnership Developments
MOU with BLM and USFS – Natural Resource & Cultural Management
MOU with USDA ARS – Mitigation Sites
Advisory Panel for Logan and Malheur River Wildlife Mitigation Projects
Malheur River Bull Trout Working Group
Cooperative Management Partnerships – TNC, DU & OWT
Pending MOU with OSU – Research and Development
Partnership with Center for Invasive Plant Management
Local Coordination with Watershed Groups, NRCS and SWCD
9. Strategic Plan for Ongoing and Future Mitigation Projects All projects are working together to promote habitat enhancement throughout the subbasin by:
- setting the stage for long-term fisheries
recovery,
- addressing noxious weed issues directly,
- forming advisory groups and ensuring public
participation and involvement,
- coordinating efforts with other subbasins.
