The rrbasin_barriers shapefile (polygons) contains weighted scores that assess the impact of fish barriers on sixth field watersheds within the Rogue River Basin. Original barrier data were provided by the Rogue Basin Fish Access Team (RBFAT).This is Figure 18 from the report titled "Assessment of Aquatic Habitat Monitoring Data in the Rogue River Basin and Southern Oregon Coastal Streams" (January 2003) by Conservation Biology Institute.For more information, please review the full report.

Conservation planning aims to optimize outcomes for select species or ecosystems by directing resources toward high-return sites. The possibility that local benefits might be increased by directing resources beyond the focal area is rarely considered. We present a case study of restoring river connectivity for migratory fish of the Great Lakes Basin by removing dams and road crossings within municipal jurisdictions versus their broader watersheds. We found that greater river connectivity could often be achieved by considering both intra-jurisdictional and extra-jurisdictional barriers. Focusing on jurisdictional barriers alone generally forfeited <20 (median = 0%) of habitat gains for those who value solely habitat...

Ecological connectivity between the Great Lakes and their tributaries is widely impaired, and many agencies and organizations are currently investing in restoring these connections to enhance target fish and wildlife populations. To assist in targeting these investments, we have been developing spatial data on the location and attributes of barriers (dams and road-stream crossings) and fish breeding habitat throughout the Great Lakes basin to analyze the optimum strategy for enhancing connectivity and restoring fish migrations. The proposed work will result in guidance for barrier restoration at scales from individual watersheds to the entire basin, refine methodologies for spatial analysis of barriers, and provide...

Our goal was to predict road culvert passability, as defined by culvert outlet drop and outlet water velocity, for three fish swimming groups using remotely collected environmental variables that have been shown to influence the passability of road culverts.We generated four boosted regression tree models, one for road culvert outlet drop and one each for the three culvert outlet water velocities, and predicted the probability of impassable road culverts on low-order streams based on the models. Independent variables in the modelsincluded the upstream area draining to the culvert, slope at the culvert, stream segment gradient and stream reach gradient.Gradient of the stream segment was the most important predictor...

A key challenge in aquatic restoration efforts is documenting locations where ecological connectivity is disrupted in water bodies that are dammed or crossed by roads (road crossings). To prioritize actions aimed at restoring connectivity, we argue that there is a need for systematic inventories of these potential barriers at regional and national scales. Here, we address this limitation for the North American Great Lakes basin by compiling the best available spatial data on the locations of dams and road crossings. Our spatial database documents 38 times as many road crossings as dams in the Great Lakes basin, and case studies indicate that, on average, only 36% of road crossings in the area are fully passable...

In many large ecosystems, conservation projects are selected by a diverse set of actors operating independently at spatial scales ranging from local to international. Although small-scale decision making can leverage local expert knowledge, it also may be an inefficient means of achieving large-scale objectives if piecemeal efforts are poorly coordinated. Here, we assess the value of coordinating efforts in both space and time to maximize the restoration of aquatic ecosystem connectivity. Habitat fragmentation is a leading driver of declining biodiversity and ecosystem services in rivers worldwide, and we simultaneously evaluate optimal barrier removal strategies for 661 tributary rivers of the Laurentian Great...

This feature layer is a spatial representation of most of the DAM facilities in the StreamNet database. Information about the location of each dam was collected from StreamNet personnel at WDFW (Washington Dept of Fish & Wildlife), ODFW (Oregon Dept of Fish & Wildlife), IDFG (Idaho Dept of Fish & Game), and MFWP (Montana Fish, Wildlife & Parks) and the tabular information about each dam in the StreamNet database was then added to each dam point in the GIS layer. California data comes from the StreamNet's partner project "CalFISH" (http://www.calfish.org) which contributes data compatible with the StreamNet database.
