Section 4. Objectives, Tasks and Schedules

Objectives and Tasks

Objective Task
1. Develop comprehensive spatial and tabular/attribute database (IFIM models) to characterize physical processes in the Flathead River affected by flow from Hungry Horse Dam a. Compile spatial database (GIS map) of the Flathead River from the South Fork confluence downstream to Flathead Lake
1. b. Integrate smaller scale information on riparian land use and vegetation, macro-habitat classification, thermal modeling results and hydrographic modeling results.
1. c. Integrate detailed channel topography for micro-habitat and sediment transport modeling
2. Use IFIM models to compare the results of alternative dam operational strategies on aquatic resources a. Develop an array of potential scenarios for managing river flows to meet biological objectives
2. b. Determine cost-effective operation to minimize predation of juvenile bull trout and westslope cutthroat trout by lake trout and northern squawfish
2. c. Determine the magnitude, timing and duration of the peak flow event needed to move fine sediments to enhance aquatic production
2. d. Establish flow ramping rates to minimize riparian vegetation loss due to bank failure and lateral migration

Other Budget Explanation

Schedule Constraints: This project was scheduled to begin in FY97 and run for three years. However, the project could not be launched until 1998 and was deferred until FY98. A draft RFP was submitted to BPA so that solicitation of proposals can be initiated in spring 1998.

Section 7. Abstract


Construction of Hungry Horse Dam on the Flathead River (completed in 1952), caused many physical and biological changes in the Flathead River downstream. Hypolimnetic releases from the dam artificially cooled the river from 1952 through 1996 when a selective withdrawal structure was installed on the dam, allowing dam operators to control the water temperature in the tailwater. Now that the thermal pollution from Hungry Horse Dam can be mitigated, a primary manageable threat to watershed health is dam operation. Flow fluctuations from power and flood control operations create an extensive, low productivity, varial zone, greater substrate imbeddedness and species shifts in the aquatic insect community which has become less diverse and less productive. A combination of man-caused factors resulted in the decline in native gamefish species mountain whitefish, westslope cutthroat and bull trout, and a significant increase in abundance of non-game native species, the Columbia River chub or peamouth, northern squawfish and introduced rainbow trout and northern pike . Pursuant to measure 10.3A.18 of the FWP, this project will use a modified form of the Instream Flow Incremental Methodology (IFIM) to examine the mechanisms by which dam operation effects the riverine community and their environment, and propose operational guidelines to mitigate negative effects. Results will expand the utility of the existing reservoir model HRMOD, verify and refine the Integrated Rule Curves developed for Hungry Horse Dam. This project will be directly contracted by BPA through competitive bid.
