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.
