IDEM invites public to meeting on Deep River/Portage Burns watershed

Back To Front Page

The Indiana Department of Environmental Management (IDEM) has begun developing a Total Maximum Daily Load (TMDL) for the Deep River-Portage Burns Watershed in Lake and Porter counties at 1 p.m., Thursday, Dec. 5, at the Lake County SWCD & Extension Office, 880 E. 99th Court, Suite A, in Crown Point.

IDEM will provide a midterm report for the public, at a meeting.

TMDL is the term for a calculation to determine the maximum amount of pollutants, or pollutant load, a stream can receive and not violate state water quality standards. Where streams violate water quality standards, IDEM develops TMDL reports that include calculations and describe sources of pollutants within the watershed, methods used to analyze data, pollutant reductions needed to restore water quality, and actions for improving water quality.

Citizens who attend the meeting on the Deep River-Portage Burns Watershed TMDL will learn about water quality monitoring that began on April 2013, steps in the TMDL process, how the community can be involved and progress so far.

Water quality can be impacted by “nonpoint source pollution” and “point source pollution.” Nonpoint source pollution happens when rain water and snowmelt wash contaminants off of the land into lakes and streams. Common nonpoint source pollutants include excess chemical pesticides and fertilizers used in residential, business and agricultural areas, bacteria from animal waste and failing septic systems, excess salt and oil residue on roadways, and erosion and sediment from bare soils.
