Drinking Water Wells - Northern Lower Peninsula [arcgis_rest_services_OpenData_public_health_MapServer_5]

The data in these six files is derived from Wellogic, the Michigan Department of Environmental Quality statewide ground water database. The six files combined contain information on over 575,000 spatially verified water well records. The six files are intended to provide water well information for wells in counties clustered by geographic region: Upper Peninsula, Northern Lower Peninsula, East Central Lower Peninsula, West Central Lower Peninsula, Southwest Lower Peninsula and the South Central – Southeastern Lower Peninsula. The files are constructed to be easily merged, containing the same number and type of attribute fields. Although the derived data in these files represents the best readily available data, the six files do not represent a complete database of all wells or well records in existence. Until January 1, 2000 not all water well records for new wells in Michigan were entered into Wellogic. For wells drilled before 2000 the rate of inclusion is highly variable from one county to another. Further, there is a quality control check on location that may exclude a limited number of wells from Wellogic from the six files made available on this site.

Watershed Boundary - 12 Digit [arcgis_rest_services_OpenData_hydro_MapServer_20]

This dataset at 1:24,000 scale is a greatly expanded version of the hydrologic units created in the mid-1970's by the U.S. Geological Survey under the sponsorship of the Water Resources Council. The WBD is a complete set of hydrologic units from new watershed and subwatesheds less than 10,000 acres to entire river systems draining large hydrologicunit regions, all attributed by a standard nomenclature. Development of the Watershed Boundary Dataset started in the early 1990's and has progressed to the format and attributionthat is now being distributed. The delineation and attribution was done on a state basis using a variety of methods and source data. Each state HU dataset has gone through an extensive quality review process to ensure accuracy and complianceto the Federal Standard for Delineation of Hydrologic Unit Boundaries (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/national/water/watersheds/?cid=nrcs143_021630) before and during submittal to USDA-NRCS National Geospatial Management Center (NGMC).
