Current Projects
Aquatic Inventories Aquatic Inventories Project (AI)
Created in 1990, the Aquatic Inventories Project is a statewide freshwater and estuarine research program. The project assesses aquatic habitat, conducts fish presence and absence surveys, monitors fish populations, establishes salmonid watershed prioritization, monitors habitat restoration projects, and reconstructs historical salmonid life history.

Willamette Spring Chinook

Coded-Wire Tags

Coastal Chinook Research and Monitoring Program (CCRMP)
The Coastal Chinook Research and Monitoring Program (CCRMP) conducts research on populations of Chinook salmon on Oregon's Coast.  The majority of this work is focused on north migrating populations important to Oregon's participation in the Pacific Salmon Treaty.  Our work includes generating robust population estimates for specific basins, estimating harvest of returing adults, and determining appropriate methods and tools to monitor Chinook populations in a cost effective and accurate way.

 Coded-Wire Tags (CWT)
Evaluation of hatchery programs requires monitoring of activities in the hatchery, as well as, where, when and how many hatchery fish are caught or return to spawn. Our objectives are to (1) monitor adult production from hatchery releases; (2) evaluate rearing and release strategies that will help to improve the survival rate of hatcheryproduced smolts; and (3) establish a comprehensive long-term database that will provide information needed to address issues of biology, allocation, and conservation.

Upper Willamette River Bull Trout Studies

Upper Willamette River Bull Trout (UWRBT)
Populations of bull trout Salvelinus confluentus have declined markedly over the last century as a consequence of habitat alteration, introduction of nonnative species, overharvest, and eradication efforts.  Accordingly, the U. S. Fish and Wildlife Service listed bull trout as threatened in the coterminous United States under the Endangered Species Act in 1999.  Bull trout are native to the Willamette River basin and presently occupy the McKenzie River and Middle Fork Willamette River drainages.  ODFW, in cooperation with other agencies participating in the Upper Willamette Bull Trout Working Group, has conducted research, monitoring, and bull trout translocation efforts for more than two decades.

Native Fish Investigations Native Fish Investigations (NF)
The Native Fish Investigations Project conducts statewide research on Oregon’s non-anadromous native fish. Our mission is to provide scientific information on the status (distribution and abundance), life history, genetics, and habitat needs for Oregon’s native fish populations. This information is intended to aid fish managers and landowners in developing appropriate conservation and recovery strategies, and on-going monitoring plans.
Oregon Adult Salmonid Inventory and Sampling Oregon Adult Salmonid Inventory and Sampling (OASIS)
The Oregon Adult Salmonid Inventory & Sampling project is responsible for conducting monitoring and research to assess the status of wild stocks of Coastal and Lower Columbia anadromous salmonid populations. Duties include coordinating and conducting coastal and lower Columbia River salmon spawning ground surveys, as well as, implementing reseach to improve inventory methods. Other duties include technical assistance to various fishery managment programs.
Salmonid Life-Cycle Monitoring Salmonid Life-Cycle Monitoring (LCMP)
In 1998, as part of the Oregon Plan for Salmon and Watersheds, the Oregon Department of Fish and Wildlife (ODFW) began monitoring survival and downstream migration of salmonid fishes (Oncorhynchus spp.) in coastal basins. As a part of this program the Salmonid Life-cycle Monitoring project developed three objectives: 1) estimate abundance of adult salmonids and downstream migrating juvenile salmonids, 2) estimate marine and freshwater survival rates for coho salmon (Oncorhynchus kisutch) and 3) evaluate effects of habitat modification on the abundance of juvenile salmonids.
Scale Analysis Project Fish Life History Analysis Project 
The Fish Life History Analysis Project (formerly “Scale Analysis Project”) is part of the Western Oregon Research and Monitoring Program within the Northwest Region. The project provides technical support within this program and to other programs, research projects, and management districts within the agency. The project uses fish scales to provide age composition, hatchery or wild origin, life history, and growth information as needed. Data provided by this project are used for run size forecasts, status assessment, identification of hatchery strays, and growth analyses.  The project will be expanding into analyses of the microstructure of fish otoliths to supplement the data gleaned from scales.
Willamette Hatcheries Biological Opinion Project Willamette Biological Opinion Project (WBOP)
The Willamette Salmonid Inventory Project was created in 2002 in response to the NMFS Biological Opinion on hatchery operations in the Willamette Valley. Project activities fall into four broad categories: 1) trapping of adults, 2) sampling of hatchery returns 3) monitoring natural production , and 4) fishery assessments (creel surveys).
Western Oregon Rearing Project Western Oregon Rearing Project (WORP)
In 1998, the Oregon Plan for Salmon and Watersheds mandated that the Oregon Department of Fish and Wildlife establish annual summer surveys to monitor juvenile coho salmon in Oregon Coastal streams. The objectives of these surveys are to: 1) monitor trends in the abundance and distribution of juvenile coho in each of five coastal coho Gene Conservation Areas (GCAs); and 2) provide information needed to investigate the relationships between freshwater habitat characteristics, adult spawner abundance, and juvenile recruitment.
Willamette Spring Chinook Willamette Spring Chinook Project (WSC)
The Willamette Spring Chinook Project hopes to help managers collect information that will lead to a management strategy for spring chinook salmon in the Willamette and Sandy basins that (1) protects the genetic integrity of natural populations, and (2) maintains sport and commercial fisheries and the programs that support them. A research proposal was created in 1996 with five (5) objectives.
