Illinois State Water Survey and Illinois State Geological Survey Contract Report 2005-11, Champaign, Illinois, 57 p. http://www.isws.illinois.edu/pubdoc/CR/ISWSCR2005-11.pdf This dataset contains Groundwater Contribution Area (GCA) boundaries for selected Illinois Nature Preserves in polygon feature classes. The nominal scale is 1:24,000. The spatial reference is GCS_Clarke_1866 (geographic coordinate system), Clarke_1866_Lambert_Conformal_Conic (projected coordinate system), and D_Clarke_1866 (datum). These data may be used in conjunction with other data related to Illinois natural resources, including spatial data related to Illinois Nature Preserve boundaries (from the Illinois Nature Preserves Commission) and other spatial data created in conjunction with this dataset and outlined in the Locke et al. (2005) methods report that is identified in the Cross References section. This additional data includes Regional Groundwater Contribution Area (RGCA) boundaries created based on local hydrogeologic data and Adjusted Surface Watershed Area (ASWA) boundaries created based on surface topographic data. The average locational errors associated with GCA boundaries is variable due to the variable locational errors associated with the multiple data sets utilized to construct GCA boundaries. The GCA boundaries were developed by staff of the Illinois State Water Survey (ISWS) and Illinois State Geological Survey (ISGS) with their methods and results being summarized in a contract report for the Illinois Nature Preserves Commission (Locke et al. 2005). This report is identified in the Cross Reference section and includes an electronic link to a PDF (the link was active as of 6/10/2011). This report included GCA boundaries for the following Illinois Nature Preserves: Bluff Springs Fen, Braidwood Dunes and Savanna, Cotton Creek Marsh, Elizabeth Lake, George B. Fell, Gladstone Fen, Goose Lake Prairie, Illinois Beach, Lake in the Hills Fen, Lockport Prairie, Romeoville Prairie, Sand Ridge, Searls Park Prairie, Spring Grove Fen, Trout Park, Volo Bog, and Yonder Prairie. The Braidwood Dunes GCA boundary was revised in 2007 to incorporate new hydrogeologic information. These Groundwater Contribution Areas (GCAs) were created using methods developed by the Illinois State Water Survey (ISWS) and the Illinois State Geological Survey (ISGS) for use in estimating areas that contribute groundwater to Illinois nature preserves. Methods and results were described by Locke et al. (2005), a contract report for the Illinois Nature Preserves Commission that is identified in the Cross Reference section. The method was developed to determine areas where a Class III (also known as Special Resource) ground-water designation could potentially be applied under the Illinois Administrative Code. A petition for designation of Class III groundwater to the Illinois Environmental Protection Agency (IEPA) must include a minimum set of information including site descriptions and maps. In addition to detailed site descriptions and information, the IEPA has required that each petition include a GCA estimate and full documentation of the estimate describing data and methods used. While not specifically called for under Section 620.230b, a GCA estimate is necessary to identify where Class III groundwater quality standards would be implemented. To develop GCA estimates, the INPC contracted with the ISWS and ISGS to assess data availability and determine an estimation method. Locke et al. (2005) documents the method used to develop GCAs for the 11 Illinois nature preserves in this dataset. Further information is available in the Locke et al. (2005) methods report identified in the Cross Reference section. These GCA areas are the most applicable to be proposed for Class III groundwater protection, given current data availability, funding, and technology. These GCAs also identify important ground-water resources of nature preserves where it may be most effective to focus management or acquisition efforts. As appropriate, this method also may be used to determine GCAs at other Illinois nature preserves and natural areas. Because resources were not available to collect new hydrogeologic data at each nature preserve, the method for determining GCAs used pre-existing data that were available at the time of GCA creation. This dataset is subject to revision as more GCA boundaries are calculated and as additional data or improved methods become available in the future. Additionally, contribution areas are dynamic. A GCA changes constantly as a result of fluctuations in recharge and water usage (e.g., variations in climatic conditions, alterations to surface permeability, and increased or decreased pumping). Estimates based on historic data may be inaccurate unless a comparison is made with current hydraulic conditions. In addition, resource and planning agencies must continue to evaluate activities (e.g., pumping from water-supply wells or other development) proposed within and near the GCA for their potential to change groundwater-flow conditions and thus GCAs. The term "final" is used to distinguish GCAs that attempt to include all areas that may contribute groundwater to a preserve. These final GCAs may incorporate one or more regional GCA's (created for individual aquifers) as well as an Adjusted Surface Watershed Area (a delineated surface watershed that has been adjusted based on significant hydrologic features). The use of the term "final" does not indicate the GCA boundaries may not be revised. The data do not replace the need for detailed site-specific studies. The information is not appropriate for, and is not to be used as, a geodetic, legal, or engineering base. The information has no legal basis in the definition of boundaries or property lines and is not intended as a substitute for surveyed locations such as can be determined by a registered Public Land Surveyor. At present, the data are managed by Randy Locke and Jim Miner of the Illinois State Geological Survey (within the Prairie Research Institute at the University of Illinois at Urbana-Champaign). The nominal scale of 1:24000 is based on the nominal scale of the U.S. Geological Survey topographic maps which were used to determine Adjusted Surface Watershed Areas (ASWAs) for Nature Preserves. The scales of ground-water surface maps used to construct regional GCAs may differ from the 1:24000 scale. The spatial reference is derived from that used by the Illinois Nature Preserves Commission (in 2006) to display Nature Preserve boundaries. The GCAs derived directly from Locke et al. (2005) include Bluff Springs Fen, Elizabeth Lake, George B. Fell, Goose Lake Prairie, Illinois Beach, Lake in the Hills Fen, Lockport Prairie, Romeoville Prairie, Spring Grove Fen, and Volo Bog. The Braidwood Dunes and Savanna GCA boundary was revised by ISGS and ISWS staff in 2007 to incorporate new hydrogeologic information contained in a report by Conestoga-Rovers & Associates (2007). This report is identified in the Cross Reference section. Data from Meyer et al. (1998), a report identified in the Cross Reference section, was used to create regional GCAs (for individual aquifers) for the following nature preserves: Elizabeth Lake, Gladstone Fen, Lake in the Hills Fen, Spring Grove Fen. Data from Roadcap et al. (1993), a report identified in the Cross Reference section, was used to create regional GCAs (for individual aquifers) for the following nature preserves: Lockport Prairie, Romeoville Prairie. en 20090331 publication date In work Annually -89.404113 -87.800569 42.505216 41.232113 3026239.750000 3456647.000000 2989369.203509 3447136.500005 none groundwater ground water Ground-water Contribution Area GCA Illinois Nature Preserves Commission INPC Class III Class 3 Groundwater Contribution Area none Illinois ISGS information must be obtained directly from the ISGS or from an authorized distributor.

A link is provided in the Cross References section. There is no quantitative assessment of attribute accuracy available. The average locational errors associated with GCA boundaries is variable due to the variable locational errors associated with the multiple data sets utilized to construct GCA boundaries. Most Illinois nature preserves are expected to lack sufficient groundwater-level data for GCA estimates. Because there are more than 300 Illinois nature preserves, cost and time prohibit the collection of sufficient field data to map head surfaces at all preserves with high resolution. Therefore, estimating GCAs for most preserves in the state requires the use of proxy data (e.g., topography and surface watersheds), indicators (e.g., groundwater discharge and geologic deposits), uncompiled data when available, and best professional judgment. While not readily quantifiable, a reduction in GCA accuracy should be expected when proxy data are used. Please refer to Locke et al.
