SHEBOYGAN COUNTY: Crystal Lake MOD FLOW

Sheboygan County will hire a contractor to develop a conceptual groundwater model with defined boundaries and layering structure. The final report will contain the following elements: 1) A narrative to describe the model and provide discussion of the data needed for the completion of a database for model calibration along with maps identifying data collection needs and kinds of data still needed. 2) Printout of field data. The collection of field data will include piezometer nests on Elkhart and Little Elkhart lakes and construction of monitoring wells to evaluate groundwater flow conditions. 3) Assembling and accessing existing groundwater level, water quality studies, groundwater modeling and other task done by DNR. 4) Evaluation and comparison of the database for the watersheds of Crystal, Elkhart and Little Elkhart. Water chemistry, inter relationships with adjacent wetland and water sources will be looked at. 5) Development of groundwater maps. 6) Identification of gaps in data. 7) Development of the preliminary MODFLOW model as described in the grant proposal. 8) Development of a proposal to complete the modeling in subsequent grants. 9) Two paper copies and one electronic copy of the report will be provided to the department.10) Minutes from the public meeting regarding the findings of the study.
