Contract Title: Fifteenmile Creek Habitat Restoration Project O & M  - M & E
Performance/Budget Period:October 1, 2005 -September 30, 2006

Fifteenmile Creek supports the eastern-most stock of wild winter steelhead in the Columbia River Basin.  High quality spawning and rearing habitat in the subbasin is limited, and the winter steelhead population is believed to be below historic levels.  Oregon Department of Fish & Wildlife has classified this steelhead population as a species of concern for management purposes.  The National Marine Fisheries Service included the Steelhead inhabiting Fifteenmile Creek in the Middle Columbia ESU group and listed them as a threatened species.

The Fifteenmile Basin Fish Habitat Improvement Implementation Plan was developed cooperatively by Bonneville Power Administration, ODFW, Mt. Hood National Forest, and the Confederated Tribes of the Warm Springs.  The purpose of the plan is to guide habitat rehabilitation efforts in the subbasin, and to be consistent with Program Measure 703 (c)(1) - Action Item 4.2 of the Columbia River Basin Fish and Wildlife Program.  The goal of the implementation plan is to restore historic escapement levels of wild winter steelhead in the Fifteenmile Subbasin to mitigate for losses of fish production caused by the Federal Columbia River Power System.

This statement of work addresses the ongoing operation, maintenance, monitoring and evaluation of the Fifteenmile Creek winter steelhead habitat rehabilitation project. This corresponds to Phase IV, the operation and maintenance phase of the implementation plan.  This statement of work covers the period from October 1, 2006 through September 30, 2007, where ODFW will continue with the operation and maintenance of completed riparian habitat treatment measures on Fifteenmile Subbasin. The ODFW will also continue with physical monitoring throughout the sub basin.

General Description of Project Area

The Fifteenmile Creek subbasin, drains 373 square miles of Wasco and Hood River counties. Originating on the east slope of Lookout Mountain about nine miles east of Mt. Hood, Fifteenmile Creek flows northeast out of the timbered higher elevations, swings north through the dry land wheat country, then west to empty into the Columbia River near The Dalles.  The stream flows into the Columbia River approximately one and a half miles east of The Dalles, Oregon at river mile 192.  Principle tributaries to Fifteenmile Creek include Ramsey, Pine, Dry, Fivemile and Eightmile Creeks.  Eightmile Creek, the largest tributary, drains 118 square miles and joins Fifteenmile Creek two miles above the confluence with the Columbia River.  The mainstem of Fifteenmile Creek drops approximately 6,405 feet in 54.5 miles from the headwaters on Lookout Mountain to the mouth. The upper stream reaches are moderate to steep in gradient, while the lower 43.6 miles are a relatively low with an average gradient of 0.6 %.  

The flora of the Fifteenmile Creek subbasin ranges from dominantly fir and pine coniferous forests in the headwaters to grasses, perennial forbs, oak and widely scattered pine woodlands bordering the agricultural lands at the middle and lower elevations. The lower half of the basin is predominantly open range and dry land agricultural land.  The geology of the area consists of numerous outpourings of Columbia River basalt. Basalt basal flows create an impermeable layer underlying the area. The area is characterized by a high spring runoff from winter snowmelt combined with spring rains, followed by low summer flows that are heavily influenced by agriculture irrigation withdrawals

Goals, Objectives and Tasks

The ODFW project activities are limited to the operation and maintenance of completed habitat treatment measures. These objectives and tasks are believed to be necessary to provide the continued operation and maintenance of completed habitat treatment measures.  In addition some objectives and tasks will disperse information and monitor and evaluate results of past restoration efforts.
