collected data from 2012 to 2020.

*4.1. REON Cyberinfrastructure*  With the collaboration of REON, a cyberinfrastructure website, both data collection and the development of maps were accomplished. This platform provided an efficient watershed characterization by exposing significant guidelines from the EPA watershed characterization manual. This manual provides the basis to meet water quality and watershed management goals. Physical and natural features, land use, waterbody conditions, pollutant sources, and waterbody monitoring information are the data needed to characterize a watershed [56]. The first step for the watershed characterization was to develop the watershed delineation for the three watersheds. The results were then uploaded With the collaboration of REON, a cyberinfrastructure website, both data collection and the development of maps were accomplished.

This manual provides the basis to meet water quality and watershed management goals. Physical and natural features, land use, waterbody conditions, pollutant sources, and waterbody monitoring information are the data needed to characterize a watershed [56]. The first step for the watershed characterization was to develop the watershed delineation for the three watersheds. The results were then uploaded to the REON website to show watershed boundaries. Additionally, NPS and PS pollution layers were included in each watershed to facilitate the characterization process based on EPA watershed characterization. The cyberinfrastructure gathers existing watershed boundaries, hydrology, land use, NPS pollution, PS pollution, water quality stations, and flow stations to support the overview of the watershed characteristics. Three maps were created: Watershed delineation results, NPS pollution, and PS pollution maps. The maps created facilitated the watershed characterization by integrating geospatial data for NPS and PS pollutants for each watershed individually. The development of maps portrayed in the cyberinfrastructure helped stakeholders collaborate in the characterization by providing inputs for each potential source that could contaminate the area. The web user interface at the regional level is available for every stakeholder regardless of time or location.
