Water Quality in Indiana

Water Quality in Indiana > Watershed Assessment and Planning Watershed Assessment and Planning

The Watershed Assessment and Planning Branch houses the watershed monitoring, assessment, Total Maximum Daily Load (TMDL) and Nonpoint Source (NPS) programs. Staff conducting the monitoring programs operate through the Probabilistic and Targeted Sections and collect water chemistry, E. coli, fish, macroinvertebrate, aquatic habitat and algae data. The data are analyzed and used for statewide and watershed specific surface water-related assessments, development of the Integrated Report, and planning and restoration projects. Support for the programs is provided by staff in the Technical and Logistical Support Section, which includes quality assurance/quality control of collected and submitted data, spatial and tabular data management, and laboratory, equipment, and vehicle management and logistics. The branch also supports water quality standards development, NPDES permitting and compliance activities, public health advisories, such as for fish consumption and blue-green algae, volunteer monitoring efforts through the Hoosier Riverwatch and Clean Lakes Programs, and the IndianaMap.
