Exploration drilling started at proposed dam site

Published on Back To Index

Crux crews are onsite near Whiteriver, AZ to complete core drilling and sampling at the proposed Miner Flat dam site.

Thirteen angled core holes and a total of approximately 3,365 feet of drilling will be completed. Access to borings is being achieved through a combination of track vehicle and helicopter, and core recovery in the area has proven challenging in the past. All operations are taking place on White Mountain Apache Tribe lands and require close coordination with tribal representatives.

If constructed, the dam will cross the north fork of the White River, measuring approximately 160 feet high and with a crest length of approximately 450 feet. The proposed project, including the dam, as well as a storage reservoir, a pumping plant, treatment facilities, and a distribution system, would provide long-term water stability and reliability to the Fort Apache Indian Reservation.

Crux is performing permeability testing throughout drilling operations and Vibrating Wire Piezometers will be installed in eight of the thirteen borings. Downhole imaging will be completed in select borings by Crux Oriented Borehole Logging (COBL). Drilling operations commenced on March 7, 2014 and Crux expects to be onsite until June 2014.
