Land transformations occurring from energy development and agrarian use have altered the natural connectivity of fish communities inhabiting prairie waterways. The nation’s prairie waterways are obstructed by thousands of barriers that include road culverts, irrigation diversions, and dams. Connectivity is essential for the long term viability of aquatic species. One of the most promising adaptive management strategies for addressing impacts to aquatic systems by climate change and other landscape stressors is increasing connectivity. The purpose of this research is to characterize swimming abilities of three northern plains fish species; the sauger, the longnose dace, and the fathead minnow. The results of the...

In the last century, the U.S. led the world in dam building for many purposes, including hydropower, irrigation, flood control and water storage. While dams can benefit society, they also cause considerable harm to rivers. Dams have depleted fisheries, degraded river ecosystems, and altered recreational opportunities on nearly all of our nation’s rivers. Today, many dams that were once at the epicenter of a community’s livelihood are now old, unsafe or no longer serving their intended purposes. American Rivers’ Dam Removal Database includes all dam removals in the United States (of which we have been made aware) in which a significant portion of the dam has been removed for the full height of the dam, such that...

Streams across the world are highly fragmented due to the presence of in-stream barriers (e.g., dams and stream-road crossings), many of which restrict or block fish passage. Retrofitting or replacing these structures is a high priority for restoring habitat connectivity for native fishes and other aquatic organisms in the Pacific Northwest. The task of restoring habitat connectivity for problematic stream-road crossings is daunting given the many thousands of barriers that are present and the massive financial investments required. Further, the potential risks to road infrastructure from flooding, debris flows, and climate change will need to be addressed to ensure the best allocation of resources. In this study,...
This report provides a final update of work performed for the period beginning December 20, 2010 and ending December 31, 2012. The report describes two umbrella projects: (1) to improve fish passage and landscape connectivity for native species and 2) to determine the thermal effects on fish species sensitive to climate change. The work was performed through a partnership led by the Western Transportation Institute at Montana State University and the Bozeman Fish Technology Center (BFTC) of the United States Fish and Wildlife Service. The report is divided into five chapters that provide details on accomplishments to meet specific objectives outlined in our proposal during the period. Several of the projects that...

StreamNet's Potential Fish Passage Barrier dataset captures both natural and man-made in stream features that have the potential to block fish passage (culverts, dams, debris jams, cascades, falls, etc.). Where information exists, fish passage ability is captured. This dataset is maintained and updated on an annual or semi-annual basis. The JUNE, 2012 publication dataset includes almost 60,000 features across the states of Washington, Oregon, Idaho, western Montana and California. Where possible, all barrier locations are georeferenced to StreamNet's regionally standardized routed hydrography layer (MSHv3) enabling comparison and analysis of barrier locations within the context of StreamNet's larger data holdings...

The Oregon Fish Passage Barrier Data Standard (OFPBDS) dataset contains barriers to fish passage in Oregon watercourses. Barriers include the following types of natural or artificial structures: bridges, cascades, culverts, dams, debris jams, fords, natural falls, tide gates, and weirs. The OFPBDS dataset does not include structures which are not associated with in-stream features (such as dikes, levees or berms). Barriers are structures which do, or potentially may, impede fish movement and migration. Barriers can be known to cause complete or partial blockage to fish passage, or they can be completely passable, or they may have an unknown passage status. The third publication of the OFPBDS dataset (Version 3)...
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...

A Group layer that includes Oregon Fish Passage Barriers database, and removed or replaced features.
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...

Objectives: 1. To make in-stream structures that were placed into Muddy Creek for stream reclamation passable to fish while still maintain the purpose and function of the original structure. 2. To reconnect 50 miles of contiguous stream habitat for BLM sensitive fishes including the Colorado River cutthroat troat, bluehead sucker, flannelmouth sucker, and roundtail chub. Background: Muddy Creek is the only system in Wyoming where viable populations of BLM sensitive Colorado River cutthroat trout, bluehead sucker, flannelmouth sucker, and roundtail chub coexist. Bluehead sucker, flannelmouth sucker, and roundtail chub populations have declined by about 50% range-wide and although Muddy Creek has the largest population...
Migration barriers and resulting habitat fragmentation are a major conservationconcern for freshwater fishes. Characterizing the swimming abilities of fish is vital forfishway design and identifying potential movement barriers. The objective of this studywas to assess the swimming performance of two of the most widely distributed prairiefishes, the large-bodied, large river sauger Sander Canadensis, and the small-bodied,small stream longnose dace Rhinichthys cataractae. Swimming performance for bothspecies was assessed using a variety of metrics (passage success, maximum ascentdistance, maximum sprint speed) in an open channel flume over a range of velocities(sauger, 51, 80, 93 cm/; dace, 39, 64, 78, and 90 cm/s),...
