Upper Skagit Indian Tribe

FY15 Project
Freshwater Productivity and Diversity of Skagit River Steelhead – Year 5

Project Summary

The Upper Skagit Indian Tribe will continue research on the freshwater abundance, age-class composition, juvenile growth and survival of steelhead smolts by operating rotary screw traps in two tributaries of the Skagit River, Illabot and Hansen creeks. Focusing their primary juvenile objectives to the tributary scale they have combined their adult monitoring return component designed to enumerate steelhead encountered in the Skagit River that were tagged as smolts in the initial years of study.  USIT’s long term vision is to build a monitoring program focused in tributaries of the Skagit River that draws relationships between adult abundance, juvenile production, and habitat metrics, thereby promoting a watershed scale estimate of steelhead population dynamics that are critical to both harvest management and recovery planning.

FY14 Project
Freshwater Productivity and Diversity of Skagit River Steelhead – Year 4

Project Summary
The Upper Skagit Indian Tribe will continue research on the freshwater abundance, age-class composition, juvenile growth and survival of steelhead smolts by operating rotary screw traps in two tributaries of the Skagit River, Illabot and Hansen creeks. Based on results from the spring 2012 and 2013 outmigration study, USIT refocused their primary objectives in 2014 to the tributary scale and added an adult return component designed to enumerate steelhead encountered in the Skagit River that were tagged as smolts in the initial years of study.  USIT’s long term vision is to build a monitoring program focused in tributaries of the Skagit River that draws relationships between adult abundance, juvenile production, and habitat metrics, thereby promoting a watershed scale estimate of steelhead population dynamics that are critical to both harvest management and recovery planning.

FY13 Project
Freshwater Productivity and Diversity of Skagit River Steelhead – Year 3

Project Summary
The Upper Skagit Indian Tribe will continue research on the freshwater abundance, age-class composition, juvenile growth and survival of steelhead smolts by operating rotary screw traps in two tributaries of the Skagit River, Illabot and Hansen creeks.  Based on results from the first two years of study, USIT plans to refocus their primary objectives to the tributary scale, and add an adult return component designed to enumerate steelhead encountered in the Skagit River that were tagged as smolts in their initial years of study.  USIT’s long term vision is to build a monitoring program focused in tributaries of the Skagit River that draws relationships between adult abundance, juvenile production, and habitat metrics, thereby promoting a watershed scale estimate of steelhead population dynamics that are critical to both harvest management and recovery planning.

FY12 Project
Freshwater Production Evaluation of Skagit River Steelhead Using Mark-Recapture Methodology

Project Summary
The Upper Skagit Indian Tribe will continue to develop a basin-wide abundance estimate of outmigrating steelhead smolts from the Skagit River through the use of a multiple-trap design, which marks and releases steelhead smolts from tributary traps and uses the captures and recaptures of marked smolts at the Burlington main stem Skagit trap to estimate total outmigration of smolts. Analysis of such information will be used to investigate freshwater and marine survival rates, with an emphasis on detecting and utilizing information on annual differences in survival for restoration evaluation and abundance forecast purposes, and developing recovery goals.

FY10 Project
Evaluating Spatial and Seasonal Distribution of Stream Dwelling Juvenile Salmonids Chinook and Steelhead and Determining Habitat Preferences of those Juveniles

Project Summary
The Upper Skagit Indian Tribe will determine the seasonal and spatial distribution of yearling (stream-type) life history salmonids in the Skagit River, WA, with an emphasis on Chinook salmon and steelhead trout. The results of this investigation are intended to fill data gaps necessary for effective recovery planning of Chinook salmon and steelhead in the Skagit River basin and inform similar efforts in the Puget Sound basin.

FY09 Project
Red Creek – Reach 6 Hydro-Geomorphic Restoration

Project Information
This project was directly administered by the EPA; the project description, funding amount, and information for all FY09 Tribal Implementation Assistance Grants can be found on the EPA website.

FY08 Project
Hansen Creek Alluvial Fan and Wetland Restoration – Floodplain Restoration, Phase I

Project Summary
The Upper Skagit Tribe project will contribute towards implementation of the Hansen Creek alluvial fan and wetland restoration that will restore historic floodplain connectivity, riparian habitat and the hydrologic and sediment transport processes to improve salmon habitat and productivity. The project located within the Skagit River system is a freshwater floodplain restoration of 140 acres of pasture and isolated depressional wetlands to include 53 acres of alluvial fan, 87 acres of riverine forested, flow-through wetlands. The project benefits refuge, rearing, foraging, migration and spawning habitats for Chinook, coho, chum, pink salmon, steelhead and cutthroat trout, and a number of other wildlife species.
