Local bedrock aquifer diagram
Detailed Description
Local aquifers in bedrock in western Montana and Wyoming have sufficient permeability so that water moves laterally through them to recharge unconsolidated-deposit aquifers in an adjacent stream valley. Ultimately, the water is discharged from the unconsolidated-deposit aquifers to lakes or streams.

Minor aquifers, confining units, and areas identified as "not a principal aquifer"
Aquifer maps often include large-to-small areas that are designated "minor aquifer," "not a principal aquifer," or "confining unit.” These are usually areas are underlain by low-permeability deposits and rocks, unsaturated materials, or aquifers that supply little water because they are of local extent, poorly permeable, or both.
