Water obtained from Dakota sandstone. In pumping the well for several mod 
the water which originally stood at a level of about 830 feet below the ground li 
was lowered gradually to about 1,000 feet below the ground line, and the dillicul 
in pumping the limited amount of water (about 30 gallons a minute) was so grei 
that the well was abandoned.
