3.5 Groundwater

  1. Most of the major wetlands in the subwatershed were identified in the FAW as combination recharge-discharge wetlands.  Several discharge wetlands are located in the upper subwatershed in the Baker Park Reserve.  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 17, there are a number of areas in the subwatershed that are very highly or highly sensitive aquifer impacts, especially the wetlands in the Painter Creek corridor.
  3. Wellhead Protection Areas and associated Drinking Water Sensitivity Management Areas have been identified for the cities of Long Lake and Plymouth wells within this subwatershed.  Stormwater management within those areas should be coordinated with wellhead protection plans.
  4. Groundwater hydrology is an important component in the base flow for area streams.  Protecting existing groundwater flow regimes must remain a priority.
