3.5 Groundwater

  1. Many of the major wetlands in the subwatershed were identified in the FAW as discharge or combination recharge-discharge wetlands.  Several recharge wetlands are located in the two areas of the subwatershed north where depth to bedrock is lower than in other parts of the subwatershed.  As development occurs it will be critical to maintain runoff and infiltration rates to help maintain hydrology to these wetlands.
  2. As described in Section 2.5.6 and Figure 16 and Figure 17, there are a number of areas in the subwatershed that are very highly or highly sensitive to aquifer impacts.
  3. Wellhead Protection Areas and associated Drinking Water Sensitivity Management Areas have been identified for the cities of Minnetrista, Minnetonka, and Plymouth within this subwatershed.  Stormwater management within those areas should be coordinated with wellhead protection plans.
