The Lower Alsea River Watershed Analysis contains information which characterizes the processes and trends for resources of concern, and provides a context relating the function of this lower portion of the watershed to the Alsea River Basin as a whole. Critical problem areas both inside and outside federal lands are...
This project, commissioned in 1998, is part of the MidCoast Watersheds Council's efforts to better understand the status and condition of the area's natural resources and to work with interested landowners to enhance and protect important areas.
"This report provides information on some important economic aspects of the recreational and commercial crab fisheries in Alsea Bay. In 1989, the Department of Fish and Wildlife collected selected types of economic information from recreational crabbers who were surveyed in the Alsea Bay fishery. Commercial fishing data is based on...
This report describes sediment testing done on the Yaquina River benthos between river miles 6 and 11 (a section between Yaquina and Toledo). The sediments were found to be safe for in-water disposal, thus enabling dredging to proceed.
GIS technology has reached a point where it can be utilized by nonprofessionals in a desktop environment. This paper reviews the implementation of a pilot project for developing a localized-natural resource GIS. The resulting GIS was custom designed to answer questions posed by fish and wildlife biologists who need to...
Tributaries of the Tualatin River cascade down high gradient slopes for relatively short distances, then flow into the low gradient mainstem which meanders for much of its length. The gentle, east-facing slopes of Oregon's Coast Range provide the geomorphic and climatic template for the watershed's patterns of discharge, water quality,...
This investigation is focused on smallmouth bass in the Umpqua River system. This investigation contains methods of fish sampling used and, later, describes which methods were more effective for specific tasks. It includes population size, density/structure, mortality rates, and age/growth data regarding the smallmouth bass. See also: Umpqua River smallmouth...
"A study of smallmouth bass in the Umpqua River System was initiated in 1987 and continued in 1988. Results of that work were reported in a progress report. The study was continued in 1990 after a one-year lapse. This report summarizes results of the work conducted in 1990. Objectives of...
Hedonic Pricing is an effective and versatile method of
estimating the relationships between market prices and
environmental quality in a world of changing natural resource
decisions. One natural resource policy not yet studied using
Hedonic Pricing is the protection of free-flowing rivers. As
the pressures of development and outdoor recreation...
