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...

The 14-m-tall Marmot Dam was removed during the summer of 2007, and the cofferdam protecting the working area was breached during a storm on October 19, 2007, allowing approximately 750,000 m3 of reservoir deposit to be eroded freely and released downstream to the Sandy River. Prior to the Marmot Dam removal, sediment transport models were developed to predict the transport dynamics of both gravel and sand, providing key pieces of information for stakeholders and regulatory agencies to select the most appropriate dam removal alternative. A monitoring program was implemented following dam removal that was designed to examine model predictions and assess when potential fish passage issues related to dam removal were...

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),...

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 map shows information on the location, type, and fish passage barrier status of road-based stream crossing structures, dams, and miscellaneous instream structures in Washington State. It is a subset of data extracted from the Washington Department of Fish and Wildlife's (WDFW) Fish Passage and Diversion Screening Inventory (FPDSI) database. It includes data compiled from several WDFW and non-WDFW fish passage barrier inventory efforts. The data are statewide in scope but do not represent a comprehensive or complete inventory of fish passage barriers. The data set is updated continually as inventory efforts are ongoing. The data are used to identify, locate, and prioritize correction of man-made fish passage...
Due to anthropogenic activities and large stochastic events within the drainage, Gooseberry Creek no longer has a population of CRC above a man made Gabion structure. Gooseberry Creek is a small tributary and cannot support a large population of CRC to persist without connectivity to Trout Creek and Sage Creek. When passage is provided through the structures, approximately 1.5 miles of Gooseberry Creek will be available for CRC and other native fish for spawning, rearing and other life history needs. This project is part of an ongoing effort to improve aquatic and riparian habitat within the Greater Little Mountain area to increase the range of the native Colorado River cutthroat (CRC) trout. The Gooseberry Fish...

This dataset accompanies the article "Upstream experience and experimental translocation of invasive bigheaded carps results in increased upstream passage success at a navigation lock in a large river". The data come from the experimental capture and tagging of invasive bigheaded carp with acoustic transmitters and physically moving some groups farther downstream. These transmitters emit signals that are detected and recorded on receivers that are strategically placed above, within, and below Mississippi River Lock and Dam 19 (LD 19). Once the data from the receivers were downloaded, we could show when successful upstream passage through LD19 occurs and compare the origin of the fish and the physical characteristics...
