Project Overview
Basics
Upper Thirtymile Low-Tech Process-Based Restoration
Implementation
The purpose of this project is to restore geomorphic, hydrologic
and biological process to approximately 5.7 miles of Thritymile Creek to improve habitat for the threatened Mid-Colombia River steelhead. Habitat impairments currently include:
• High surface water temperature
• Lack of channel complexity
• Ephemerally low and/or intermittent surface flow

Focal Species
Focal Species
Broad management goals for the Thirtymile Creek watershed are linked to federal recovery planning for Mid-Columbia steelhead listed as threatened under the Endangered Species Act (NWPC 2005). The ecologically distinct Lower John Day steelhead population depend on tributary habitat within Thirtymile Creek for spawning and rearing. Federal recovery planning for Columbia Basin salmonid populations listed under the ESA have specifically listed tributary habitat quantity and quality as a primary factor limiting their population productivity (NMPS 2009).
Implementation and Ecological Results
Implementation and Ecological Results
Proportion (%) of the valley bottom functioning as part of the active channel and active floodplain. Expected to increase resulting from structural intervention due to pond creation, floodplain connectivity, and creation of multi-threaded channels.
• POOL FREQUENCY – Frequency (pools / km) of pools created by bed scour. Expected to increase resulting from the structural treatments. Pool habitat provides refuge for juvenile steelhead during periods of drought and high temperatures, and velocity refuge during high – flow periods.
• BAR FREQUENCY – Frequency (bars / km) of in-channel depositional geomorphic units within the project area. Depositional bars are indicative of spawning habitat used by adult steelhead. Expected to increase resulting from the structural intervention as a function of increased in-channel hydraulic diversity.
• PERCENT VALLEY BOTTOM SURFACE FLOW – Percent of the valley bottom longitudinal length (as measured along the center of the valley bottom) with persistent surface flow during late summer drought periods. Surface flow should be recognized if present in any channel (i.e., primary or non-primary channel). Expected to increase in response to flow attenuation and increased surface – groundwater exchange.
• PERCENT VALLEY BOTTOM RIPARIAN DOMINATE – Proportion of the valley bottom in which the dominate plant community is composed of wetland and/or riparian plant species. Expected to increase with an expanding active channel and floodplain, floodplain inundation frequency, groundwater elevation, as well as due to grazing management and riparian vegetation planting treatments.
DAM ABUNDANCE – Count of beaver dams and artificial dams within the project area. Beaver activity and populations are expected to increase resulting from increased riparian vegetation, and creation of deep-water cover from structural restoration treatments.
