Watersheds in Eaton County, Michigan, USA. These watersheds were created using a hydro-enforced 10ft DEM derived from 2010 Lidar in conjunction with ECGIS hydrology vector layers. The watersheds are simply elevation-based and pay no heed to man-made drainage that may run counter-grade. Delineation occurs confluence to confluence along the flowlines and also around lakes that are 4 hectares or larger.

The Michigan’s Major Watersheds - Subbasins shape file depicts the drainage areas of 20 square miles or greater at geographic features such as the mouth of a river or the location of a USGS stream flow collection station. The shape file is used to determine hydrologic parameters for determining a range of flows in watershed analysis.

A watershed layer specifically utilized in wetland mitigation and mitigation banking. These areas along with eco-regions determine which watershed will be utilized as part of the process. These watersheds tend to differ slightly from that of other watershed boundaries. The layer was originally created in 1997. No updates will be made to this layer at this time.

This data set provides an estimate of annual groundwater recharge for each public land survey section in Michigan. Groundwater Inventory and Mapping Project, a cooperative effort between the Water Bureau - Michigan Department of Environmental Quality (now Michigan Department of Environment, Great Lakes, and Energy), USGS - Michigan Water Science Center and Michigan State University - Institute of Water Research, RS&GIS and Biosystems and Agricultural Engineering. This project was mandated by P.A. 148 (Michigan Acts of 2003). Major funding was provided by EGLE (MDEQ at the time), supplemented with additional funds from the USGS Cooperative Water Program.Public Law 148 required the MDEQ to obtain a map of state-wide groundwater recharge. The US Geological Survey and Michigan State University have created this data set to meet that need.Accuracy of the recharge estimate is estimated to be +/- 2.44 inches/yr in the western and northern Lower Peninsula, +/- 1.1 in/yr in the southeastern Lower Peninsula, and +/- 2.9 inches/yr in the Upper Peninsula. Areas in the eastern Upper Peninsula (Luce, Chippewa, and Mackinaw Counties) may have higher error because of relatively poor representation of specific geologic environments.Base flow separations were compiled 208 USGS streamflow gages in Michigan from those completed by Neff and others (2005). Within each region, an average recharge rate was calculated based on the baseflow yield. Residuals were computed for each streamflow gage.Watershed characteristics describing the geology, land cover, and general climate characteristics of the gaged watersheds were also compiled. These data were analyzed in Systat v.11 using a forward stepwise regression procedure to identify watershed characteristics that might be useful in predicting the value fo the residual. Within the eastern Lower Peninsula, the significant predictive variables, in addition to area, were: agricultural land use, urban land use, annual growing degree days, annual precipitation, and percent of the watershed underlain by lacustrine deposits. Within the western Lower Peninsula, the significant predictive variables, in addition to area, were: winter (December through March) precipitation, the percentage of the watershed underlain by till, and the percentage of the watershed occupied by forests. In the Upper Peninsula, the significant predictive variables, in addition to area, were: growing degree days and winter precipitation.Each of these predictive variables were calculated for each Public Land Survey section, the data used to predict a residual, then the residual added to the base recharge prediction for the region.

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 subwatersheds less than 10,000 acres to entire river systems draining large hydrologic unit 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 attribution that 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 compliance to the Federal Standard for Delineation of Hydrologic Unit Boundaries before and during submittal to USDA-NRCS National Geospatial Management Center (NGMC).

This data set provides estimates of the ground-water contribution to stream flow, frequently referred to as base flow, in cubic feet per second. The baseflow of a stream or river is the amount of groundwater discharged from an aquifer to the watercourse. This discharge occurs year-round, and fluctuates seasonally depending on the level of the water in the aquifer. Baseflow is supplemented by direct runoff during and immediately after precipitation or melt events, resulting in peaks on a hydrograph showing stream flow through time. The process of dividing these peaks into base flow and runoff is called hydrograph separation. Hydrograph separations were completed for all USGS stream- flow gaging stations in Michigan that had more than 10 years of daily records. Sites that were clearly affected by upstream impoundments (lakes, dams) were excluded. No attempt was made to detect or correct for trends in the data. This may lead to some errors in the comparison of streams with data from different time periods if there is an underlying temporal trend in the data, but inclusion of all records in the analysis was necessary to increase the data pool and provide better spatial coverage. Watersheds were delineated for each of the 208 stream-flow gaging stations, and various characteristics of each watershed, such as topographic relief, surficial geology, land cover, growing degree days, annual and winter-season precipitation, and others were tabulated. Regression modeling, described in the Technical Report, was used to estimate the baseflow for each steam segment of the 1:100,000-scale National Hydrography Dataset.

n the Great Lakes, grid systems defined by latitude and longitude minutes have been used for a number of decades as a fishery standard for data reporting. The Michigan Department of Natural Resources (MDNR) Fisheries Division created this GIS layer in 2019 to depict the MDNR Michigan Great Lakes grid (v3.2) standard for Fisheries Division applications for the waters of the State of Michigan, and for Canadian waters in the St. Clair Detroit River System (SCDRS), as of June 2019. This GIS layer was created by incorporating grid boundaries and ID values from a number of existing grid standards. This layer is a composite grid that incorporates grid boundaries and ID values from the following GIS data standards for different areas of the Great Lakes: 1) 10-minute grids for Lakes Huron, Michigan, Superior and the St. Mary’s River came from the Institute for Fisheries Research (IFR) version 1 (v1) of the 10-minute grids. 2) 10-minute grids for Lake Erie came from version 2 of the IFR 10-minute grids created by the Great Lakes GIS (GLGIS) project, and 3) 5-minute grids for SCDRS came from 5-minute grids developed by the GLGIS project. Version 1 of the IFR 10-minute grids were created in 1998, and only covered Lakes Huron, Michigan, and Superior, and the St. Mary’s River. This is the GIS dataset that was used as the grid standard for the 2000 consent decree. The grid boundaries and ID values in v1 were based off of the paper maps depicted in the 1989 Status of the Fisheries Resource Report (Technical Review Committee, 1989) with some very minor grid boundary differences likely caused by bringing the paper map into a digital GIS format. In v1, 10-minute grids do not always have rectangular boundaries where each side represents 10-minutes of latitude and longitude, especially near the shoreline. In order to create the v3.2 composite layer, some features in the v1 GIS dataset that were missing ID values were assigned ID values based on historical creel maps or nearby grid ID values. Version 2 of the IFR 10-minute grids was created in 2006 and provides coverage forall five Great Lakes, but only partial coverage in the connecting channels, with no coverage in SCDRS. In contrast to v1, 10-minute grids in this dataset are true 10-minute grids with rectangular sides that strictly follow 10-minute latitude and longitude lines (along with some cases where two true 10-minute grids were combined into one grid cell with one ID value). Due to the differences in grid boundaries, there are some different ID values across v1 and v2. The GLGIS 5-minute grid GIS dataset was created in 2006 at IFR. This layer contains rectangular 5-minute grids that are true 5-minute grids, with each side of every grid representing 5-minutes of latitude or longitude. 5-minute grids were used for SCDRS in v3.2 to align with historical data reporting standards in the region, and because there are no 10-minute grids that fully cover SCDRS. 5-minute grids created by the GLGIS only exist for SCDRS, Lake Erie, and Lake Huron, and the reason for this is unknown. SCDRS grids on the Canadian side of the basin are included in v3.2 for Fisheries Division data reporting needs that may include Canadian areas of SCDRS, but these grids in Canadian waters may not represent the standard that is actively used by Canadian agencies. In order to create the v3.2 composite, grid cells from the various GIS data sources were merged together for water bodies as specified above. In v3.2 the grids are almost exactly as they appear in the source data (with minor edits such as edge matching) except where 10-minute grids 602 and 603 in Lake Erie from Version 2 were replaced with GLGIS 5-minute grids. These grids cover the transition between the Detroit River and Lake Erie, where 10-minute grids are too large for some fisheries data reporting purposes. Therefore in v3.2, the two 10-minute grids were replaced with four 5-minute grids from the GLGIS 5-minute grid dataset. ID values were kept from the 5-minute grids for the two northern cells but the two southern grids cells retain ID values from the GLGIS v2 10-minute grids (602 and 603). This was done to allow continuity with historical data that has been recorded for 10-minute grids 602 and 603, but users need to be aware that these ID values in v3.2 are now associated with 5-minute grids instead of 10-minute grids. Version 3.2 was subsequently slightly altered to create Version 3.3, which replaced the shoreline in Northern Lake Huron and slightly altered the shoreline near the Soo Locks in the St. Mary's River to match zones, closures, etc. described in the Consent Decree that were depicted with a more detailed shoreline than the v3.2 shoreline. This was done so that those zones, closures, etc. could be depicted along with the Michigan Great Lakes Grids and have alligning shoerline depictions (see Figures 13, 12 & 16 for examples of the more detailed shoreline).
