DNR Cooperative Ground Water Monitoring Locations - Feature Table| Field Name | Valid Values | Definition | Definition Source |
|---|
| Station_ID | - | The station identifier in the Wiski Database. | |
| Name | - | Station name. | |
| Easting | - | UTM Easting coordinate. | |
| Northing | - | UTM Northing coordinate. | |
| Latitude | - | Latitude coordinate in NAD 1983. | |
| Longitude | - | Longtitude coordinate in NAD 1983. | |
| Station_type | - | Type of hydrologic monitoring station. Stations can have multiple characteristics and are combined by a ;. See station characteristics list on the Appendix tab. | |
| County_Name | - | County name in which the station is located. | |
| County_Number | - | Code associated to the county in which the station is located. | |
| Station_manager | - | State personnel responsible for maintaining station. | |
| USGS_ID | - | USGS ID for station | |
| Permit_number | - | Permit number associated with the station. | |
| DNR_obwell_id | - | DNR Well ID number. First 2 digits are county codes, last 3 digits are sequentially ordered wells by time. | |
| Well_Type | - | 1: DNR Observation wells: A monitoring well which is used for measuring groundwater level. In most instances, these wells are dedicated to monitoring long-term, background groundwater levels in an aquifer and are a part of the DNR’s statewide Observation Well Network. Typically these wells are not used for pumping, irrigation, or other activities that will dramatically affect water levels. Data collection methods are standardized and data quality is controlled and assured. 2. Wetland piezometers: Hand driven observation wells with casings of 1.25 to 2 inch diameter, no deeper than 15 feet below land surface or 10 feet into mineral soil, for the purpose of measuring water levels in and below unstable soils (e.g. peat, muck). 3.Permit related well: Well for the purposes of groundwater appropriations or a well monitoring groundwater appropriations for a permit. Data collection methods and quality vary. 4: Other unclassified category wells: Well that is not defined by the descriptions above, or may be a well designated for a special project. | |
| Read_Status | - | Read status will have information on either the readability of the well, whether it is being read, and in some rare cases, who is doing the reading such as a well being read by a volunteer. Read status: Yes, No, Sealed, YRT = Instant Measurements, YVOL (Volunteer), YVW (Vibe Wire), Missing. | |
| Aquifer | - | Aquifer(s) that the well is open to. If well is open to multiple aquifers, then there will be two different aquifer codes. For example, CTCGCMTS is a well that is open from the CTCG aquifer (Tunnel City Aquifer) to the CMTS aquifer (Mt. Simon Aquifer), hence a multi-aquifer well. For aquifer codes refer to Appendix Tab. | |
| Aquifer_Name | - | Name of aquifer. | |
| Aquifer_Type | - | Type of aquifer being measured. | |
| Aquifer_Code | - | Aquifer code. | |
| Completion_Date | - | Date well was completed. | |
| Completion_Depth | - | Depth of well in feet. Equals case depth + screen below ground. | |
| Diameter | - | Diameter of well pipe in inches. | |
| Screen | - | Length of well screen in feet from bottom of casing. | |
| Case_Depth | - | The depth of the casing (in feet) below ground. | |
| Case_Material | - | A casing is a solid or slotted length of pipe, typically steel or PVC plastic that is used to keep a bore open in alluvial sediments, sand dunes or unstable rock. (C = Concrete, I = Iron, P = Plastic, S = Steel, U = Unknown, W = Wood). | |
| Well_Nest_ID | - | Used to specify a group of wells that are right next to each other. | |
| Organization | - | Organizations associated with the station, multiples separated by a ;. | |
| Firstfieldvisit | - | Date of first field visit. | |
| Lastfieldvisit | - | Date of most recent field visit. | |
| Measure_point_date | - | Survey date of Measure point value. | |
| Measure_point_value | - | Surveyed elevation of the point in which the well is measured from. | |
| Station | - | Unique station identifier. This ID is the same as the Station_id without the leading letter. | |
| URL | - | Url to the cooperative stream gaging or cooperative ground water monitoring websites | |
| Has_provisional_data | - | Binary variable: 0 for no provisional data. 1 for has provisional data. | |
| Has_approved_data | - | Binary variable: 0 for no approved data. 1 for has approved data. | |
