Summary
MARIS is an internet-based information sharing network that allows multiple states to provide a common set of variables via a single web interface. MARIS is not a "dataset" but rather links specific content of multiple states' datasets. MARIS does not capture all of the information from each state's aquatic dataset only a subset of data collected as part of aquatic species sampling surveys. The MARIS structure was developed by a consortium of state fish and wildlife agencies and implemented through contracts with various universities. In the past, federal agency partners have provided the core funding for developing and implementing MARIS as well as broad guidance on the content of the system. In 2014 the U.S. Geological Survey discontinued [...]

In 2014 the U.S. Geological Survey discontinued support to the MARIS system. The published data will remain available in ScienceBase at https://www.sciencebase.gov/catalog/folder/529e0108e4b0516126f68e3c.
State boundaries are outlined in green. States with a blue fill color are included in the MARIS database. States with a gray fill color are anticipated to be added to the database in its next release. States with a purple fill color have fish and/or water quality data but do not have lat/longs associated with the data.
MARIS was initially developed to serve a need for states to provide data in response to data requests from multiple federal agencies. However, it has evolved to provide a potentially valuable tool for state agencies to provide data in response to numerous data inquiries from members of the public or nongovernmental organizations. The initial focus of MARIS was to provide data elements related to the status and trends of fisheries, but this thinking has evolved into a broader utility of the data including serving as a conduit for states to contribute data for the National Fish Habitat Action Plan (NFHP) and other stakeholders.
