Welcome to the Water Quality Decision Support Application (WQDSA)


The Water Quality Decision Support Application (WQDSA) is a shared vision among a diverse group of stakeholders lead by the International Water Institute (IWI).


The MN WQDSA  data/viewer (Sand Hill River Watershed) is funded by a Minnesota Clean Water Fund grant awarded to the IWI by the Board of Water and Soil Resources using dollars generated through the Legacy Act Amendment.


The ND WQDSA data/viewer (Wild Rice Watershed)  is funded through the ND Department of Health Non-Point Source Program with in-kind support provided by the Dickey/LaMoure County, Stutsman County, Richland County, and Wild Rice Soil Conservation Districts.


The overarching goal is to create, distribute and demonstrate the use of water quality related products derived from high resolution topographic data collected using Light Detection and Ranging (LiDAR) technology in a structured decision making process. The pilot application demonstrates how these data can be used for describing and understanding the condition of a watershed, assessing pollutants sources, prioritizing sub-watersheds relative to Best Management Practice (BMP) implementation and developing a BMP implementation plan for agricultural landscapes.


This (WQDSA) provides land and water managers with geospatial data and online tools to prioritize, target, and measure conservation practices on the landscape to achieve water quality objectives identified in local and state plans and ensure that decisions to spend public funds are strategic, defensible and transparent. Local and state water plans consistently identify two primary objectives: 1) reduce erosion and sediment in surface runoff from agricultural fields, and 2) reduce peak flow events that transport the largest sediment loads by accelerating rates of field and channel erosion. When fully developed, the WQDSA is envisioned to allow users to 1) identify the water quality problems, 2) establish goals and objectives, 3) reference planning documents, 4) interactively create maps of projects for demonstration and marketing, 5) save projects in a database for future refinement,and 6) potentially export relevant information in a format suited to existing planning and reporting tools (e.g. eLINK).


The products and applications developed through this project are one component of the Red River Basin Decision Information Network(RRBDIN). The vision for the RRBDIN is to serve as the regional home and repository for a number of shared applications and data to improve decision-making within the Red River Basin.
