  • Slides of the operational system

  • Conclusion and next steps


The water withdrawal assessment process
The Water Withdrawal Assessment Process

  • Oversee the design and development of a “water withdrawal assessment tool”

    • Develop methods, criteria, and definitions for establishing ‘adverse resource impacts’ for streams and lakes.

    • Make recommendations on the policy aspects of the model.

      Adverse Resource Impact Means: Decreasing that part of the flow such that the streams ability to support Characteristic Fish Populations is Functionally Impaired.

Rain and Snow – Recharge to area

1. The Withdrawal Model

  • Model needs to know how much water is in the local aquifer

  • Automatically determines where several nearest streams are.

    • Apportions the withdrawal effect among streams

  • Calculates the likely reduction in flow due to the proposed withdrawal

Water legislation cont
Water Legislation cont.

Senate Bill 860 (as enacted) PUBLIC ACT 185 of 2008

  • Require the DEQ, on October 1, 2008, to make available for testing and evaluation an internet-based waterwithdrawal assessment tool.

    House Bill 4343 (as enacted) PUBLIC ACT 184 of 2008

  • Require the DEQ to notify certain local entities by e-mail if a proposed withdrawal falls into a particular category.

  • Allow the notified entities to form a water resources assessment and education committee in order to assess trends in water use in the withdrawal's vicinity and educate water.


Wellhead protection program
Wellhead Protection Program

  • 1986-Amendments to the Federal Safe Drinking Water Act (SDWA)

  • 1994-State program was developed by the Michigan Department of Natural Resources (MDNR) & Michigan Department of Public Health (MDPH)

  • Protect Public Water Supply Wells through proactive land-use planning and management




High impact targeting hit system
High Impact Targeting (HIT) System

Use of the High Impact Targeting (HIT) GIS Web-accessible System is demonstrated in the following figures. Over the web, sediment risk maps can be examined and “zeroed” in on to locate high potential sediment delivery sources (fields).
