This data set contains 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 weekly as inventory efforts are ongoing. Please note that the "Date Updated" value of this item refers to the ArcGIS Online item's date, not the data contained within.

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. This dataset complies with version 1.1 of the OFBPDS data standard. New optional attributes have been added to describe fish passage barrier feature modifications, to describe supplementary information (via a comments field) and also to linear reference the barrier features to the National Hydrography Dataset. The OFPBDS dataset now contains over 40,000 barrier features from 19 separate sources including: Oregon Department of Fish and Wildlife (ODFW), Oregon Department of Transportation (ODOT), Oregon Department of Water Resources (OWRD), Oregon Department of Forestry (ODF), Oregon Watershed Enhancement Board (OWEB), Oregon Department of Land Conservation and Development (DLCD) US Bureau of Land Management (BLM), US Forest Service, Nez Perce Tribe, Benton SWCD, Washington county, Lower Columbia River Estuary Partnership and watershed councils representing the Rogue, Umpqua, Siuslaw, Santiam, Calapooia, Clackamas and Scapoose basins. The Data Steward obtained fish passage barrier data from multiple data originators between 2008 and 2019, collaborated with them to develop inclusion / exclusion criteria and dataset specific crosswalks for converting data from its original data structure to the structure of the OFPBDS. The data were then converted into the OFPBDS format and analyzed for duplication with existing OFPBDS barrier features. Where duplicates were identified, depending upon the scenario, one feature was either chosen over the other or in some cases attributes from different sources are combined. Source information is retained for each feature. The data were then loaded into the OFPBDS database. Barrier features were linear referenced (Framework Hydro only which is outside of the standard) and the corresponding optional attribute elements were populated. The data conversion, duplication reconciliation and linear referencing protocols are documented in the Oregon Fish Passage Barrier Data Management Plan. A separate dataset containing fish passage barrier features that have been completely removed or replaced (e.g. dam removals and culvert replacements) is published simultaneously with the OFPBDS dataset. The OFPBDS database is the most comprehensive compilation of fish passage barrier information in Oregon however, it does NOT represent a complete and current record of every fish passage barrier within the state. Efforts to address deficiencies in data currency, completeness and accuracy are ongoing and are often limited by lack of sufficient resources. Attributes (including key attributes such as fish passage status) are often unknown or incomplete. Consistency in attribution also varies among data originators. Field verification of barrier features and their attributes will be an important component to making this dataset current, comprehensive and accurate. Fish passage status is a key attribute. Many barrier features have an unknown passage status. For other features, the passage status may have changed since it was originally documented. Note that this metadata file is best viewed in ArcCatalog. Documentation for the OFPBDS can be found online at http://www.oregon.gov/DAS/EISPD/GEO/docs/bioscience/OregonFishPassageBarrierDataStandardv1dot1.pdf.

The Passage Assessment Database (PAD) geospatial file contains locations of known and potential barriers to salmonid migration in California streams with additional information about each record. The PAD is an ongoing map-based inventory of known and potential barriers to anadromous fish in California, compiled and maintained through a cooperative interagency agreement. The PAD compiles currently available fish passage information from many different sources, allows past and future barrier assessments to be standardized and stored in one place, and enables the analysis of cumulative effects of passage barriers in the context of overall watershed health. The database is set up to capture basic information about each potential barrier. It is designed to be flexible. As the database grows, other modules may be added to increase data detail and complexity. For the PAD to be useful as a restoration tool, the data within the PAD need to accurately depict the on-the ground reality of fish passage constraints. This requires the PAD to retrieve new barrier data and updates to existing sites and to have verified and vetted the information it receives. In 2013, new PAD data standards were designed to standardize this process, and refine the data in PAD making the data more robust. The standard is available online at: https://nrmsecure.dfg.ca.gov/FileHandler.ashx?DocumentID=78802. The new standards have been implemented for all new records since 2013. In the future, the new standards will be implemented for all existing records. If after reading the metadata, additional details about the PAD project are needed, please visit the CalFish website at www.calfish.org/PAD or refer to the PAD Methodology document at https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=19037. To send comments about data issues, corrections, edits or to map a new barrier location not yet reported in the PAD, please use the PAD Online Data Review Application: https://map.dfg.ca.gov/pad/ or send an email to: Anne.Elston@wildlife.ca.gov. Preferred citation: California Department of Fish and Wildlife, Passage Assessment Database, September 2020 Version. New as of 2020: This feature classes identifies species and life stages that may be blocked or otherwise not blocked by structures and sites. It identifies if it blocks upstream or downstream migration or both. Since one structure/site can be a barrier to more than one species or block a species and not another species there may be multiple records at each site. Please note that these are not duplicates and each site/structure has a unique PAD ID and Passage ID.

Reduced aquatic connectivity, the fragmentation of river habitats by dams, road-stream crossings (e.g. culverts) and other aquatic barriers, pose primary threats to aquatic species in the U.S. These barriers limit the ability of sea-run fish to reach freshwater spawning habitats and prevent resident fish populations from moving between other critical habitats. Many of these in-stream barriers are caused by aging infrastructure that’s beyond or near the end of its useful lifespan. Many dams no longer serve their intended purpose, and some pose a risk of catastrophic failure and are serious hazards that cause drownings. Old and poorly functioning culverts can increase the risk of road failure in storm events. Removing dams and upgrading culverts can restore functioning ecosystems, reduce liability and increase property values, and stimulate recreational opportunities and economic activity.The Aquatic Barrier Prioritization tool was developed to support the river restoration community, including planners and natural resource managers, in their efforts to target dam removals, make fish passage improvements, and other improvements to connectivity that have the most benefit for migratory fish or other species of interest.he Aquatic Barrier Prioritization tool leverages a comprehensive database of dams and other aquatic barriers in each geography where it is implemented. A suite of ecologically relevant metrics is generated for each barrier, and these metrics are used to develop a consensus-based prioritization, informed by an expert-driven project work-group, that ranks barriers based on their ability to benefit migratory fish or other objectives if removed or bypassed. Custom analysis functionality is also included in the tool that enables users to create customized prioritizations based on user-defined objectives (for example within a given state or watershed, for the benefit of a specific fish species, or modeling the removal of one or more barriers).The Aquatic Barrier Prioritization tool can be used in multiple phases of a barrier removal project. Early on, planners can use the consensus priorities or custom analysis tool to identify priority barriers that match their objectives for fish passage projects. After a potential barrier removal project has been identified, the prioritized results can be used to demonstrate the ecological value of the proposed project to funders with similar objectives. Likewise, they can be used by funders to help inform funding allocation decisions. Later, while a barrier removal project is underway, the web map can be used in outreach efforts to help dam owners, transportation agencies and the general public better understand the importance of the passage project in a regional context. Finally, after a project is complete, the results can provide measures to help managers understand and track the ecological impact of the project.

This GIS data shows locations across the state where WSDOT fish barrier corrections have been completed. Some of the WSDOT fish passage barriers that have been reported as replaced or retrofitted for fish passage may require additional work to meet current fish passage criteria. Corrected sites can become barriers due to physical deterioration of the fish passage structure itself or changes in the landscape and streambed.This GIS data is a subset of data compiled and 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.

Man-made barriers to salmonid migration include road/stream crossings, irrigation diversions and dams. Road/stream crossings are extremely numerous and often cross multiple road ownerships within a watershed. Passage impediments and delays in migration affect both adult and juvenile fish. Given the magnitude and severity of the problem, reconnecting isolated stream habitat has become an important priority for the restoration of impaired anadromous salmon and steelhead stocks. A comprehensive CDFW fish passage program is vital towards identifying, prioritizing, and treating migration barriers so that unimpeded migration of Californias salmonid populations is achieved. By coordinating resources with CDFW fisheries engineers, the Fisheries Restoration Grant Program and in conjunction with the Fish Passage Forum, a comprehensive program will aid in the recovery and de-listing of salmon and steelhead, in California. In 2008, the California departments of Fish and Game (now California Department of Fish and Wildlife (CDFW)) and Transportation (Caltrans) met with staff from the Assembly committees on Natural Resources and Transportation to discuss joint agency collaboration on prioritizing and remediating fish barriers to salmon and steelhead migration. This was in response to Senate Bill 857 requiring the California Department of Transportation to complete an assessment of potential barriers to anadromous fish prior to commencing any project using State or Federal transportation funds. In addition to the expectation that both agencies would develop a mutual list of priority barriers occurring along transportation corridors, a request was made to CDFW to provide a statewide list of priority barriers based on significance to fish migration and independent of who manages or is responsible for the stream crossing. CDFW developed its first list in 2011. CDFW has a more comprehensive list of barriers to salmon and steelhead migration; these barriers represent our effort to demonstrate and emphasize barrier priorities across both Coastal and Central Valley watercourses. As such, this spatial dataset represents the top priorities for fish passage improvement. This list is a result of compilation and review by CDFW Regional biologists and supervisors (Regions 1-5) and by the Fisheries Branch. The prioritization process considered the following criteria: 1) high likelihood to improve migration for anadromous species; 2) availability of recent data of fish and habitat; 3) willing partners and land access; 4) known political support at a local, State or national level; 5) the site is a barrier to a federal recovery plan "Core" population; 6) the watercourse is an eco-regional significant watershed; 7) CDFW is committed to monitoring before, during and after any barrier improvement project is undertaken; and 8) the site is considered to be a "keystone barrier", meaning the barrier is the lower-most in that river or creek.

The Alaska Department of Fish and Game (ADFG) maintains a fish passage inventory database (http://www.adfg.alaska.gov/index.cfm?adfg=fishpassage.database), containing data on stream crossings for fish passage collected as part of the ADFG Fish Passage Assessment Program. This program is charged with assessing the impact of state-owned road crossings of streams on fish passage. Maintaining unobstructed access to stream habitat for fish that migrate up and down these streams (such as salmon) is a critical part of maintaining these fish populations. When designed properly, culverts and bridges at stream crossings do not present a problem to fish passage, however culverts that are too small, too steep, or placed improperly can impede both upstream and downstream movement of fish. The ADFG Fish Passage Assessment Program conducts rapid (Level 1) assessments of culverts to determine their adequacy for fish passage. Streams are classified into three categories: likely to be adequate for fish passage, may be inadequate for fish passage, and likely inadequate for fish passage. The model fish chosen to determine adequacy for passage is a 55mm (juvenile) coho salmon. This fish is chosen because coho salmon are believed to be the weakest swimmers amongst juvenile salmonids, thus any culvert passable by the model fish should be passable for all other fish. For more information on Level 1 assessments, please see Eisenman, M., and G. O’Doherty. 2014. Culvert inventory and assessment manual for fish passage in the State of Alaska: A guide to the procedures and techniques used to inventory and assess stream crossings 2009-2014. Alaska Department of Fish and Game, Special Publication No. 14-08, Anchorage. http://www.adfg.alaska.gov/FedAidPDFs/SP14-08.pdf. In this dataset, the 2,500 culvert assessments in the original ADFG fish passage inventory database (http://www.adfg.alaska.gov/index.cfm?adfg=fishpassage.database) were classified according to what region the culvert is located in. The total number of culverts by category and region were summarized. The regions used are the regions of the State of Alaska's Salmon and People Project (SASAP), which notably are different than the ADFG management areas. When using this data, sampling effects must be taken into effect. The fish passage inventory database does not include all culverts in the state, just those where surveys have been completed. Additionally, this may not be an entirely accurate picture of fish passage given the fact that many areas need re-survey to update culverts that have been replaced since the initial survey. Thus some of the culvert assessment data may be out of date, as culverts are continually being replaced and improved. Finally, the model fish must be taken into account when interpreting these data. The majority of the "inadequate for fish passage" culverts are not total barriers to fish passage, however they are barriers to the model fish, which is the 55mm coho salmon.
