  Citation × Citation Citation Abstract Copy Title: Williams Hydrologic Assessment Abstract -- The Assessment is divided into two Phases. Phase 1 is a Hydrologic Assessment of the community of William to determine how human development in the Williams areas has altered the natural drainage pattern and contributed to frequent flooding in downtown Williams. Assessing sediment sources, loss of wet areas, water storage capacity, and the condition of streams identified potential restoration opportunities. Phase 2 will use information from Phase 1 to build a flood management and restoration plan. Title: Williams Hydrologic Assessment Abstract -- The Assessment is divided into two Phases.

  Citation × Citation Citation Abstract Copy Title: Fish Use of the Estuary: 1999 Tillamook Bay Monitoring Report Abstract -- The study was conducted during the summer and autumn of 1998 and the spring and summer of 1999. The fish sampling done in 1998 was used to provide an estuary-wide overview of the fish species composition and relative abundance during the mid-summer period and to test sampling gear and sampling strategies for development of a long-term monitoring program. The sampling conducted in 1999 built upon the information gained in 1998 and provided an initial test of a sampling design for long-term monitoring of the Bay's fish community. Sampling of the fish community in 1998 was conducted using beach seine, bottom trawl, fyke net and round-haul net. During 1999, initial testing of the proposed long-term monitoring program was conducted using beach seine, trawl and fyke nets. A total of 40 fish species were collected during this study whereas a total of 59 species were captured during ODFW's surveys during the mid- 1970s. Of the 40 species captured in this study, all but four were present in the mid- 1970s. Eight of the ten most abundant species present in the mid-1970s were among the ten most abundant species captured in this study. All but one of the abundant species in the beach seine catch were found throughout the estuary. All five species of anadromous salmonids known to occur in the Tillamook Bay watershed were collected during this study. However, only juvenile chum and chinook salmon were caught in any abundance. The most abundant non-salmonid species in the estuary were euryhaline marine species.

Historically, natural resource plans have addressed a single problem or only one resource. Coalition members are committed to carrying out this plan, voluntarily, over a period ofdecades. The plan will emphasize "preventive maintenance" instead ofafter-the-fact clean-up. It is the road map to guide private landowners and public-land managers in their efforts to preserve the natural and community resources ofthe Bully Creek subbasin in an economically reasonable manner for all citizens. Implementing the plan will make it possible for public and private land ownerships to achieve improvements ofcontiguous habitats.

  Citation × Citation Citation Abstract Copy Title: Little Deschutes Subbasin Watershed Assessment Abstract -- Many of the impacts to fish and wildlife habitat and water quality in the Little Deschutes River Subbasin are concentrated in the areas of housing, roads, and other human development. Most of the human population in the subbasin is concentrated around the community centers of La Pine, Gilchrist, Crescent, and Crescent Lake. There is significant dispersed development along the lower reaches of the Little Deschutes River between the communities of Sunriver and La Pine -an area characterized by gentle topography and depressions with forested wetlands, marshes and shallow lakes. Streams in this area, as illustrated by the Little Deschutes River , are low gradient and originate in the high elevation areas in the southwest portion of the watershed where there is higher precipitation. This ownership pattern has significant implications for natural resource management, as lower gradient floodplain areas tend to provide important wetland, fish, and wildlife habitat. Key Findings Fuel Loading: Having homes safe from wildfires is a concern for many residents. Fire suppression has increased the amount of dry wood in the area, creating a ready source for major wildfires. Riparian Areas and Wetlands: Loss of wetland and riparian areas , especially in the lower areas along the Little Deschutes River , has affected a number of resources. Water quality has been affected by the reduced wetlands that act as filters of nitrogen; the loss of streamside trees and other vegetation reduces shade that helps to cool water temperatures. Finally, loss ofwetlands and riparian vegetation has reduced important fish and wildlife habitats. Wildlife: The growth and development have altered wildlife habitats. Loss of wetlands, streamside vegetation, and other changes in the watershed have reduced important wildlife habitat. Roads and development have impacted migrating mule deer, increasing collisions between deer and cars and altering their migration pathways. Fish: There has been a significant loss of native trout and an increase in introduced brook and brown trout in the Little Deschutes River and tributaries. Loss of native trout is from competition with introduced species and changes in aquatic habitat and water temperatures. Water Quality: A major concern about the water in the river is unusually high temperatures in the summer and the abnormal growth of algae. Other studies indicated that there are problems with groundwater loading ofnitrogen. The high water table (with associated wetlands), and porous pumice soils contributes to increased nitrates, a by-product of septic systems and an indicator of human pathogens.

  Citation × Citation Citation Abstract Copy Title: Lower Tillamook Bay Watershed Plan and Environmental Assessment Abstract -- This document describes a plan to improve water quality and fishery habitat within the Lower Tillamook Bay Watershed while improving the economic sustainability of the dairy and livestock industry. This plan will help the agricultural community meet the requirements under the Clean Water Act and the Endangered Species Act. The financial and technical assistance provided will offer the agricultural community the opportunity to accelerate efforts already underway through the Tillamook Bay National Estuary Study and other state and local programs (Oregon Plan, SB1010 plans, etc.). Proposed is the development and implementation of conservation plans on approximately 60 dairies, 22 heifer replacement operations and 34 other livestock operations. Plans will address resource concerns on farm headquarters, pasture and haylands, riparian areas and wetlands.

  Citation × Citation Citation Abstract Copy Title: Ashland Watershed Assessment and Action Plan Abstract -- The assessment of the Ashland and Neil Creek watersheds began June 23, 2004 and concluded with this report submitted December 31, 2007. The area studied lies along Interstate 5 about ten miles north of the Oregon-California border as shown on Map 1. This project, one of many being completed across Oregon with funding from the Oregon Watershed Enhancement Board (OWEB), followed the components and methods outlined in OWEB’s Watershed Assessment Manual (July, 1999) supplemented by a later draft chapter to address Urban Issues. The process identifies voluntary individual and community Action Plans and fish-friendly practices that address priority local issues. The focus of this assessment is to document current and historic conditions; identify social and physical processes within the watershed that affect fish and riparian habitat, water quantity and quality; and current and potential hazards to the urban and rural residential environment. Soil conservation, erosion prevention, and flood protection are important factors in these issues. Most emphasis is on aquatic, hydrologic, and riparian systems. This watershed assessment builds on regional restoration priorities identified previously and provides a framework for the Bear Creek Watershed Council (BCWC) to better identify and prioritize issues affecting this watershed. Recommendations from this assessment help plan, propose and implement watershed restoration and improvement activities.

  Citation × Citation Citation Abstract Copy Title: Little Walla Walla River Assessment and Initial Action Plan (2010) Abstract -- The Little Walla Walla River and Spring Branch system is an anomaly when compared to most river systems. This non-linear combination of distributaries and an alluvial fan of spring fed creeks is treated by various state agencies and the local community as either a water conveyance network or natural stream, depending on the location being considered, or the time of year. This conundrum needs to be described and evaluated so that a coordinated approach can be developed and implemented to improve these unusual streams and the farms, fish, and wildlife that depend on them. This assessment consolidates information on the Little Walla Walla River and springs area with regards to historic and current flows, water use, land use, fish presence, habitat conditions, fish passage barriers, and water quality. This can then be utilized in developing a plan that aim to improve and preserve the environmental and economic health of this stream network, and to better define management and enhancement options. An Initial Action Plan of Goals and Actions is put forward as a discussion framework. Some of these actions are just conceptual, others are ongoing, but can be expanded to a greater scale.
