Lineage
  • A 1:200,000 scale template showing: a) surficial geology polygons (from MGS) and, b) CWI points and their static water elevation values, was created in ARCPLOT, and plotted on mylar.

  •  
  • Mike Trojan drew lines surrounding areas of estimated downward flow, upward flow and horizontal flow of groundwater. Where the static water elevation of the uppermost aquifer is greater than the static water elevation in the lowest aquifer, groundwater flow was considered 'downward.' Where the static water elevation of the uppermost aquifer is lower than in the lowest aquifer, flow was considered 'upward.' Where the static water elevation of both was roughly equal, groundwater flow was considered 'lateral,' or horizontal. In addition, Mike Trojan traced selected surficial geology type boundaries to delineate the full complement of hydrologic regimes, which represent different types of ground-water / surface interactions (see 'Entity and Attribute Information' below for a more thorough explanation of surficial regime types). Much of the decision making process was based on professional judgment and personal experience and is impossible to document here. See 'Part B, Plate 3' of the Red River Valley Hydrogeologic for a full report of surficial regimes. Also contact Mike Trojan (See 'Contact person,' above), for questions about data compilation.

  •  
  • The manuscript was digitized in ARCEDIT, and subsequent interactive changes were made by several GIS specialists based on suggestions from Mike Trojan.

Recharge area for local and regional systems; numerous lakes fed by ground-water; some high-yield aquifers present; source of recharge to underlying regional Regime 16 (See coverage, 'reg_deep.').
2Lateral flow of ground-water in local confined systems originating in Regime 1; downward hydraulic gradients contribute some recharge to Regime 16 (See coverage, 'reg_deep.').
3Upward hydraulic gradients with ground-water discharge of local systems associated with Regimes 1 & 2; numerous wetlands.
4Limited-capacity aquifers may exist in surficial sand and gravel alluvium; ground-water movement in these aquifers affected by local streams and rivers.
5Glacial deposits, primarily till; limited capacity for water supply
6Recharge area for local systems in Beach Ridge Complex; downward hydraulic gradients.
7Lateral flow of ground-water systems originating in Regime 6; flow paths and travel times are relatively short; some ground-water discharge to scattered wetlands.
8Upward hydraulic gradients with discharge of local ground-water systems in Beach Ridge Complex; numerous wetlands.
9Limited-capacity aquifers may exist in windblown deposits or surficial sands and gravels deposited by existing rivers;
10Unconfined portion of Buffalo aquifer
11Confined portion of Buffalo Aquifer or Wahpeton Buried Valley Aquifer
12Isolated aquifers in surficial near-shore lake deposits; high dissolved-ion concentrations; few aquifers exist vertically.
13Lake Agassiz sediments, mostly silts and clays; inadequate supply for domestic use.
