Wood was placed at 26 sites (with multiple jams at some sites) with an average of 66 pieces/mile or 18 pieces/site. Pre-restoration habitat surveys were completed during summer 2008 and consisted of standard ODFW AHI inventories. Post-restoration habitat surveys were completed summer 2011. A post-restoration evaluation report was completed February 2012 and is located in OWEB's files.

  Citation × Citation Citation Abstract Copy Title: OASIS - Calibration of Estimates of Coho Spawner Abundance in Smith River Basin, 2001 Abstract -- Estimates of coho spawner abundance derived from spawning surveys are a fundamental component of the Oregon Department of Fish and Wildlife’s (ODFW) Oregon Plan Monitoring (Jacobs et al. 2001). The basis of these estimates are visual counts of adult spawners in randomly selected stream reaches. To date, survey-derived estimates have not been validated against known spawner abundances. Beginning in 1999, we initiated a study at Smith River (Umpqua Basin) to calibrate survey-based spawner estimates. Smith River provides an ideal location for this type of study because it is typical of many other coastal streams that support coho salmon, contains large quantities of habitat and spawners, and provides the ability to efficiently trap and tag adequate portions of the coho run.

  Citation × Citation Citation Abstract Copy Title: NF - Sand Roller Investigations in the Willamette River Drainage, Annual Progress Report Abstract -- The purpose of this investigation was to determine the status and distribution of sand roller Percopsis transmontana populations in the Willamette River basin. Sand rollers are rare and endemic to the lower Columbia River drainage, including the Willamette River and its tributaries. Historical records are scarce. In 1945, R.E. Dimick and F. Merryfield found sand rollers to be localized in the Willamette River from Albany to Springfield, Santiam River, Rickreall Creek, Mary’s River, and the Coast Fork Willamette River. The Oregon State University museum collection has samples from the following Willamette River drainages: Coast and Middle Forks of the Willamette River, Mary’s River, Luckiamute River, Molalla River, Mill Creek, Long Tom River, and Santiam River. Their preferred habitat is quiet backwaters and pool margins of small to large rivers, usually near vegetation and woody debris over sand. The Oregon Department of Fish and Wildlife surveyed historic and recently documented locations in 2005 to determine the current status and distribution of sandrollers in the Willamette River basin. Sand rollers were collected from at least one location in most of the major Willamette River subbasins sampled.

  Citation × Citation Citation Abstract Copy Title: MWBTRP - Middle Fork Willamette Basin Bull Trout Rehabilitation and Monitoring Project, Annual Progress Report 2005 Abstract -- Bull trout in the Middle Fork Willamette Basin once moved uninhibited back and forth from spawning and rearing habitats near Diamond Peak to foraging and overwintering habitats lower in the basin. Construction of Dexter, Lookout Point and Hills Creek dams in the 1950s and 1960s without fish passage fragmented the habitat and limited the range of the population to above Hills Creek Dam. This population declined and the last confirmed bull trout sighting above Hills Creek dam was a photograph taken by an angler in 1990. Buchanan et al. (1997) described bull trout in the Middle Fork Willamette River as “probably extinct” after extensive surveys from 1993 through 1997 failed to observe any bull trout. In 1997 the US Forest Service and the Oregon Department of Fish and Wildlife began a program to reestablish bull trout in the Middle Fork Willamette. More than 10,000 bull trout fry have been transferred from the relatively healthy McKenzie population to the Middle Fork Willamette River. Adult bull trout are once again present in the Middle Fork Willamette, although natural reproduction has not been documented.

  Citation × Citation Citation Abstract Copy Title: The Distribution and Abundance of Great Basin Redband Trout: An Application of Variable Probability Sampling in a 1999 Status Review Abstract -- Using a variable probability sampling design, streams throughout the entire range of Great Basin redband trout (Oncorhynchus mykiss ssp.) were randomly sampled use the EMAP sampling protocol, such that 35 sample sites were apportioned to each of six subbasins (Silver Lake, Lake Abert, Goose Lake, Warner Valley, Catlow Valley, and Malheur Lakes). A total of 185 sites (out of a target of 210) were visited by three-person crews that conducted habitat surveys and population estimates in sample reaches whose length were nearly 20 times their channel width. A minimal sampling intensity was based on previously encountered levels of between site variance in abundance estimates for the species. The population estimate for age 1+ redband trout was 948,852 fish (+/– 21%), with confidence limits ranging from 26% to 43% of individual subbasin estimates. Age 1+ fish abundance in terms of density (fish m-2) showed no significant differences between any subbasin, while there were significant differences in biomass (g m-2), where one subbasin had significantly higher (Catlow Valley) biomasses, and one significantly lower (Goose Lake). These comparisons were supported by like differences in mean weight (g fish-2). Analysis of stream habitat characteristics and fish abundance revealed no relationship, or model, that was generally consistent throughout the Great Basin, though interpretable patterns were evident within some stream systems where sampling intensity happened to be sufficiently high. Thus while a landscape level sampling design was well suited to address a regional estimate of abundance, useful interpretation of fish and habitat relationships appeared to be embedded within the stream level of organization, and could not be addressed by the variable probability sampling design set for a minimal sampling intensity.

  Citation × Citation Citation Abstract Copy Title: AI - Year 2000 Stream Habitat Conditions in Western Oregon Abstract -- The goals of the habitat monitoring portion of the Oregon Plan program are to develop baseline statistics, describe current conditions and track trends in habitat condition over time. This program functions as the landscape link in the overall Oregon Plan monitoring program. Field work for the habitat monitoring program began in 1998 with coordinated site visitations conducted with the two other Oregon Plan monitoring programs; juvenile rearing survey and adult salmon spawning survey programs. The Oregon Plan Habitat Survey program is nested within the Aquatic Inventories Project (AIP). The AIP was begun by the Oregon Department of Fish and Wildlife (ODFW) in 1990 and has expanded to include a wide variety of inventory, modeling and monitoring efforts. The central purpose of these diverse projects is the inventory of physical aspects of the environment that are important for aquatic life and the habitat needs of salmonids and other fishes during the freshwater stages of their life history. Some of the significant ongoing or recently completed projects that are part of the AIP are: Basinwide cesus surveys, Oregon plan Habitat surveys, Restoration Project Monitoring, Salmonid Habitat and Diversity Watersheds Project, Fish Inventories, Great Basin Redband Trout, Oregon Chub Status and Recovery Project, Salmon River Estuary, and Columbia River Estuary Project.
