Goals For Changes In Pelton-Round Butte Dam Complex Operations
- The goals for changed operations of the Pelton-Round Butte Project should be to:
- Meet the requisite water quality standards for pH, dissolved oxygen, and nuisance periphyton as required by the Pelton-Round Butte Dam Section 401 Certificate Water Quality Management and Monitoring Plan, as well as those standards set forth by state and federal law.
- Eliminate nuisance periphyton communities.
- Re-establish healthy macroinvertebrate populations.
- Maintain or improve fish reintroduction efforts above Round Butte Dam.
- This would be accomplished by:
- Developing additional methods to support reintroduction of anadromous species above the reservoirs.
- Recalibration of surface water withdrawal with management of nutrient load as a priority goal.
- Determining a baseline of present conditions from the Reregulation Dam to the mouth.
- Monitoring the full 100 miles of the lower Deschutes River for the following parameters:
- Temperature, pH, dissolved oxygen, chlorophyll-a, periphyton and nutrients. Dissolved oxygen and pH collected with continuous data recorders over a minimum of 24hrs per sample period.
- Monitoring of biological impacts to include algal communities, algal biomass, and macroinvertebrates.
- Portland General Electric/The Confederated Tribes of the Warm Springs Reservation, as owners/operators of the Pelton-Round Butte Project, join with the DRA to encourage the Oregon Department of Environmental Quality to complete TMDLs for the upper and lower Deschutes basins within an acceptable time period.
