Spatial Extent of Data
 
Southern Red River Valley, Minnesota, including: all of Norman, Clay, and Wilkin counties, western portions of Mahnomen, Becker, and Otter Tail counties; part of northern Traverse County, and part of northwestern Grant County. This is the area of Minnesota within USGS 1:100,000 scale tile-sheets 1910 (Ada), 2310 (Fargo), and 2710 (Wahpeton).

Lineage
  • A 1:200,000 scale manuscript showing County Well Index points and their static water elevation values was created in ARCPLOT, and plotted.

  •  
  • Mike Trojan outlined areas of lateral or upward ground-water flow for ground-water that does not interact directly with the surface, i.e., 'deep' hydrologic regimes. Several factors were used to separate deep from surficial regimes. Deep regimes are those where: a) Tritium is virtually non-existent; b) There is no detectable dissolved oxygen; c) ground-water age suddenly increases (thus defining a vertical point where ground-water flow is primarily horizontal). Chemical information was used to verify the results of the above three methods. Chemical concentrations of major cations and anions differed significantly between deep and surficial systems. (For more detailed information, see Mike Trojan, listed as 'Contact Person,' above) Mike Trojan determined flow direction by subtracting the static water elevation of the uppermost aquifer from the static water elevation in the lowest aquifer. When the static water elevation of the uppermost aquifer is equal to the static water elevation of the lowest aquifer, flow is considered to be 'lateral,' or horizontal. When static water elevation of the uppermost aquifer is less than the static water elevation of the lowest aquifer, flow is considered to be upward.

  •  
  • The manuscript was digitized in ARCEDIT.

  •  
  • Ground-water shed divides from the coverage, 'nor_south' were added to complete the coverage. 'nor_south' represents the three major ground-water sheds of the study area: The North ground-water shed feeds the Wild Rice River, The Central ground-water shed feeds the Buffalo and Otter Tail Rivers, and the South ground-water shed feeds the Rabbit River. (See metadata for the coverage, "nor_south," for more information) The full complement of deep hydrologic regimes are thus a combination of three ground-water sheds and their ground-water flow directions. These six regimes are defined in 'Entity and Attribute Explanation,' below.
