Millions of dollars have been invested by 100s of natural resource organizations in past decades to measure habitat conditions, water quality, and biological attributes throughout the 5.5 million stream kilometers in the contiguous U.S. Much of those data could be used with spatial-stream models to develop novel insights, improve predictions at unsampled sites, perform status and trend assessments, and design efficient monitoring strategies. Brief descriptions of some open-access stream databases and hyperlinks to relevant websites or contact persons knowledgeable about accessing the data are given below. Users interested in modeling these data are responsible for understanding their characteristics and should conduct a thorough review of all metadata and any associated publications prior to using them in a spatial analysis. If you are part of a group that has developed a significant database of stream measurements available from a website and would like to have it described on this website, please contact us regarding the possibility.
1. MARIS (Multi-State Aquatic Resources Information System) is a cooperative effort between state and federal agencies to share fisheries information collected as part of ongoing sampling programs. MARIS contains >1,000,000 fish sampling and water quality records for >1,000 fish species compiled from state fish and wildlife agency and other sampling programs. The data and metadata are openly distributed through the project website. For more information, contact Andrew Loftus (firstname.lastname@example.org; 410-295-5997).
2. NAMC (National Aquatic Monitoring Center) is a cooperative venture between Utah State University and the U.S. Bureau of Land Management to encourage and foster scientifically sound watershed monitoring programs on public lands. A primary focus at NAMC is the processing of aquatic invertebrate samples and increasing the consistency and quality of aquatic resource assessments. The MAPIT (Mapping Application for Freshwater Invertebrate Taxa) online tool allows users to map and download a spatially explicit database that contains > 1.5 million records of freshwater invertebrate taxa. For more information, contact Scott Miller (email@example.com; 435-797-2612) or Chuck Hawkins (firstname.lastname@example.org; 435-797-2280).
3. USGS BISON (Biodiversity Information Serving Our Nation) is a database for occurrence data of aquatic and terrestrial organisms throughout the United States. Data were contributed by various U.S. Federal and State agencies, universities, and non-profit organizations, either directly to BISON or indirectly through their participation in the Global Biodiversity Information Facility (GBIF). BISON was initiated with millions of species records from GBIF and is integrating new records from other sources each year. For more information, visit the project website or email email@example.com.
4. USGS Aquatic BioData Retrieval system provides access to aquatic bioassessment data (biological community and physical habitat data) collected by USGS scientists from stream ecosystems across the nation. Data consist of >15,000 samples of fish-, aquatic macroinvertebrate-, and algae-community samples and conduct stream physical habitat surveys. For more information, visit the project website.
Water quality and stream flow datasets
5. USGS NWIS (National Water Information System) provides access to 1,000,000s of water quality and stream discharge records collected at stream flow gages throughout the U.S. Water-quality data are available at some gages and may consist of temperature, specific conductance, pH, nutrients, pesticides, or volatile organic compounds. The NWIS website serves current and historical data, which can be retrieved through a user-friendly interface by data category, geographic area, and dates of collection.
6. Interagency NorWeST (Northwest Stream Temperature) database contains 1,000,000s of daily temperature summaries (max/min/mean) from >20,000 unique stream sites contributed by 100s of biologists and hydrologists from >100 resource agencies across the western U.S. The data have passed through QA/QC procedures and are registered to specific reaches in the NHD-Plus hydrography layer. Data and metadata are openly distributed through the NorWeST website. For more details, please visit the website or contact Gwynne Chandler (firstname.lastname@example.org; 208-373-4372) or Sherry Wollrab (email@example.com; 208-373-4371) with specific database questions.
7. EPA STORET (STOrage and RETrieval) is a repository for storing and sharing water quality, biological, and physical habitat data collected by water resource management groups across the country. These organizations, including states, tribes, watershed groups, other federal agencies, volunteer groups and universities, submit data to the STORET Data Warehouse, which is then publicly accessible for analysis. For more details, please visit the website or email the STORET helpdesk: STORET@epa.gov.
9. EPA NRSA (National Rivers and Stream Assessment) is a national probability-based survey of river and stream physical, chemical and biological characteristics that is repeated every five years to assess status and trends of flowing waters in the U.S. More than 1,000 sites were randomly selected and were sampled in 2008-2009 and 2013-2014 using the same standardized methods. For more information, visit the website or contact Richard Mitchell (Mitchell.Richard@epa.gov).
10. DATA Basin is a science-based mapping and analysis platform that provides open access to a massive and growing number of independent geospatial datasets (>10,000) from different parts of the world. The user-friendly web-interface makes it easy to search through datasets and download those that may be useful for stream analyses. For more information, visit the website or contact the Data Basin support (firstname.lastname@example.org).
11. StreamNet is a cooperative information management and data dissemination project focused on fisheries and aquatic related data in the Columbia River basin and the Pacific Northwest. A variety of biological and habitat quality datasets are available in tabular format and as maps and GIS layers. Information is available through the online data query system, interactive mapping applications, the Data Store, or by custom request. For more information, visit the website or contact Bill Kinney (email@example.com; 503-595-3112) or Chris Wheaton (firstname.lastname@example.org; 503-595-3113).
