Article
Full-text available
Land use legacies can have a discernible influence in present-day watersheds and should be accounted for when designing conservation strategies for riverine aquatic life. We describe the environmental history of three watersheds within the Grande Ronde subbasin of the Columbia River using General Land Office survey field notes from the 19th century...
Article
Full-text available
Understanding how stream temperature responds to restoration of riparian vegetation and channel morphology in context of future climate change is critical for prioritizing restoration actions and recovering imperiled salmon populations. We used a deterministic water temperature model to investigate potential thermal benefits of riparian reforestati...
Technical Report
Full-text available
Twenty years have elapsed since a major science synthesis and planning effort led to adoption of the Aquatic Conservation Strategy (ACS) of the Northwest Forest Plan (NFP) in 1994. Their purpose was to protect and restore riparian and aquatic ecosystems on Pacific Northwest federal forest lands and to ensure that forest management plans achieved le...
Article
Full-text available
The United States Clean Water Act (CWA) is one of the key legal means in the USA to ‘restore and maintain the chemical, physical and biological integrity of the nation's waters’. Given the pervasive influence of human development and associated climate change in increasing water temperatures in streams of the USA, salmonids are particularly suscept...
Article
Full-text available
Governmental water quality agencies are faced with identifying water quality goals to protect aquatic biota, applying the best available science in development of water quality standards and associated management principles, implementing water quality laws so that there is consistency with goals, developing guidance documents for applying science t...
Article
Full-text available
Conventional water quality standards have been successful in reducing the concentration of toxic substances in US waters. However, conventional standards are based on simple thresholds and are therefore poorly structured to address human-caused imbalances in dynamic, natural water quality parameters, such as nutrients, sediment, and temperature. A...
Article
With the increasing appreciation of global warming impacts on ecological systems, in addition to the myriad of land management effects on water quality, the number of literature citations dealing with the effects of water temperature on freshwater fish has escalated in the past decade. Given the many biological scales at which water temperature eff...
Article
The examination of the development histories of four typical salmon watersheds in the Snake River Sub-basin of Idaho reveals a consistent failure to adequately protect salmon habitat. Available data and analyses show that the vast majority of watersheds managed for ''multiple uses'' have been severely degraded in their watershed and fish habitat co...
Article
Full-text available
We propose a hierarchical system of classifying stream habitats based on three increasingly fine descriptions of the morphological and hydraulic properties of channel geomorphic units. We define channel geomorphic units as areas of relatively homogeneous depth and flow that are bounded by sharp gradients in both depth and flow. Differences among th...
Article
Sediment accumulation rates in the lower Columbia River have been determined by three radiometric techniques: (1) 154Eu/152Eu activity ratios as a function of depth in the sediment column; (2) location of the 239, 240Pu activity maximum resulting from fallout input during atmospheric nuclear device testing in the period 1961–1963; and (3) the infle...
Article
Full-text available
This study derives a set of bioenergetic parameters for the blackfly Simulium spp. (Diptera: Simuliidae) and the caddisfly Hydropsyche occidentalis (Trichoptera: Hydropsychidae) and evaluates the impact of these filter feeders on the lotic environment. In addition, comparison is made between field- and laboratory-derived estimates of ingestion and...
Article
The energy budget of a fine-particle collector organism, Tricorythodes minutus Traver (Ephemeroptera: Tricorythidae), was determined under conditions (flow, substratum, temperature) representative of its natural habitat. Digestion time (gut clearance) was rapid (30 min). Ingestion values ranged widely: 33 to 220 ..mu..g dry wt depending on the type...

Thesis (M.S.)--Idaho State University. Abstract. Includes bibliographical references (leaves 312-326). Photocopy. [Pocatello] : Idaho State University, [1979?].
Article
Full-text available
Graduation date: 1988 Adequate management and scientific investigation of ecosystems depends on classification of landscape systems based on all significant bio-physical and associated cultural properties. The present classification is a hierarchical systems design that can be modeled in terms of a natural system interacting with its level-specific...

These studies incorporate a riverscape perspective of salmonid habitat conditions in streams of the American West. Our goal is to understand the ecology of salmonids to inform management practices conducive to conservation of aquatic life.
