Description:
Abstract: In order to support science-based water resource management, a systematic effort was undertaken to characterize the nature and function of the hydrogeology in Jo Daviess County, Illinois. Jo Daviess County is a karst area. Karst is a geologically and hydrologically integrated or interconnected and self-organizing network of landforms and subsurface large-scale, secondary porosity created by a combination of fractured carbonate bedrock, the movement of water into and through the rock body as part of the hydrologic cycle, and physical and chemical weathering (Panno, S.V. et al, 2017). Springs, cover-collapse sinkholes, crevices, and caves are among the defining features of a karst terrain; each of these features is found in Jo Daviess County. Examples of these features have been located in the field and characterized by scientists from the Illinois State Geological and Water Surveys (Prairie Research Institute, University of Illinois at Urbana-Champaign). An unforeseen outcome of the 2012 summer drought that impacted the U.S. Midwest and adversely affected the health and vigor of agricultural crops was it provided a rare opportunity to examine the fractured and creviced, buried bedrock surface of northwestern Illinois. Complex vegetated networks, referred to as ‘crop lines’, began to appear across the dry summer landscape of Jo Daviess County, Illinois, including adjacent western Stephenson County and southwestern Wisconsin. Primarily confined to alfalfa hay fields, the vegetated crop lines resulted from a combination of three factors: 1) the persistent extremely dry conditions, 2) a relatively thin (3 to 5 feet) overburden of unconsolidated deposits, and 3) a highly fractured and creviced bedrock surface comprised of Ordovician age Galena Dolomite. Alfalfa’s vigorous root system, may ultimately extend to depths of 6.1 m (20 feet) or more, enables it to obtain water and nutrients moving through bedrock crevices near the top of the karst aquifer, providing the necessary moisture during the 2012 summer drought to sustain the overlying healthy alfalfa plants, whereas the remaining field area exhibited stunted and sparse plant growth. The alfalfa plants forming the crop lines tended to grow denser, taller (0.5 m vs. 0.15 m), and greener than those in adjacent areas.The publication cited below provides background and context:Panno, S.V., Donald E. Luman, and Dennis R. Kolata. Characterization of karst terrain and regional tectonics using remotely sensed data in Jo Daviess County, Illinois.

Purpose: This dataset contains the digitized locations of 129 field sites within Jo Daviess County and bordering Stephenson County, IL and Lafayette County, WI where clear evidence of underlying bedrock crevices were manifested on the ground surface as complex vegetated networks, primarily within alfalfa hay fields. The primary source data used to detect the vegetated networks were multitemporal imagery acquired from multiple sources during the period of June-October, 2012.

Supplemental Information: Croplines can reveal crevice and fracture patterns present in bedrock. These lines are only visible during drought conditions and only in areas with very shallow soils where alfalfa is grown. Non-detection of croplines does not imply the lack of fractures and crevices in bedrock.

Data Quality Information:
Logical Consistency Report: The ephemeral nature of the vegetated crop lines, restricted to a relatively brief temporal period during the 2012 growing season, made their detection problematic. Complicating factors were that farm operators typically harvest (alfalfa) hayfields at various times and frequencies during the summer months; therefore, optimal field conditions and subsurface factors were necessary for vegetated crop lines to appear. Because of the large geographic area where vegetated crop lines could potentially appear within agricultural lands, aerial photography was acquired from multiple sources on multiple dates during the period from June to October 2012 for the purpose of mapping their spatial extent. Using the aerial photography as source data, all vegetated crop line features determined to be evidence of bedrock fractures and crevices were manually digitized using ArcGIS/ArcMap. A portion of the aerial photography were already digitally orthorectified, for example U.S. Department of Agriculture NAIP imagery and therefore GIS-ready; Google aerial photographs were captured in Google Earth using a specialized program, Shape2Earth (http://shape2earthengine.com/shape2earth/Home.html), which transforms the imagery to a georeferenced format. Other selected frames of aerial photography were manually georeferenced. One hundred twenty-nine locations were identified exhibiting a wide range of vegetated crop line development, and the results of the polyline digitizing yielded 17,855 separate fractures.

Attribute Definition: The U. S. Geological Survey created a hierarchical system for a national categorization of hydrologic units. As of 2010 there are six levels in the hierarchy, represented by hydrologic unit codes from 2 to 12 digits. The 6-level hierarchical system consists of the following (Name, Level#, #Digits): Region,1,2; Subregion,2,4; Basin,3,6; Subbasin,4,8; Watershed,5,10; Subwatershed,6,12. The Regions (Level 1) are geographic areas that contain either the drainage area of a major river, such as the Mississippi River, or the combined drainage areas of a series of rivers. Each Subregion (Level 2) includes the area drained by a river system, a reach of a river and its tributaries in that reach, a closed basin or basins, or a group of streams forming a coastal drainage area. Regions receive a two-digit code. The hierarchy is designed and the units subdivided so that almost all Subbasins (Level 4) are larger than 700 mi2. (1,800 km2). Larger closed Basins (Level 3) are subdivided until their subunits were less than 700mi2. The 10-digit Watersheds (Level 5) are delineated to be between 40,000 acres (approx. 60 mi2.) and 250,000 acres (approx. 400 mi2) in size, and the 12-digit Subwatersheds (Level 6) range between 10,000 (approx.15 mi2) and 40,000 acres. In addition to the hydrologic unit codes, each hydrologic unit is assigned a name corresponding to the unit's principal hydrologic feature, or to a cultural or political feature within the unit.
