Models and tools for water quality improvement

Computer models are used extensively for water quality management and Total Maximum Daily Load studies.

Models are tools used to predict how a water body will respond to changes in the amount of pollution loading a river or stream receives. This helps us identify specific strategies and numerical loading requirements in our effort to meet clean water standards across the state.

We offer the following downloadable models for public use:
