T • (Page 3) MINE ID / OR PROSPECTING ID ~ M-87-049 INSPHCTION DATE 2 4 INSPECTOR'S INITIALS GSC The dewatering activities at this operation have been confined to the Alluvial aquifer. Two of Me, Reeeler'e wells are completed in the Alluvial aquifer and the newer (390' deep) well is completed in an Arapahoe Formation aquifer. Any problems which have occurred in this deeper well do not appear to be related to the dewatering activities at the Bromley Lakes operation due to the extremely limited chance for communication between these two aquifers. Me. Reeeler'e Alluvial irrigation well has a measured water level (25'-30' bgl) similar to the 1966 depth she reported (27•bgl). This suggests that the reduced productivity may not result from a lowered water table but from reduced permeability at the well intake. This can occur when the well screen and gravel pack (or the formation in which it ie completed) become plugged with fine sediment. Considering the age of this well and the house well, this could be what is happening. In addition, conversations with a representative of the State Engineer and with Mr. Kenneth Timmerman indicate that this area has undergone drought like conditions with a general lowering of water levels. There ie another possibility that ground water levels locally may be affected by upgradient irrigation practices. The boundary markers are adequate except for the facility area. This area needs to be marked more clearly. See PB-3. I & E Contact Addreee NAME Gerritt Lana ins, O.C.
