The intent of the investigation was to determine how salt water from the Gulf moves in the river-canal complex under the influence of various combinations of fresh-water discharge and ocean tide. Information about the extent of inland movement, concentration, frequency of occurrence, and residence times of salt water in the river and canal was sought, particularly during times of farthest upstream movement of the salt water.

"CER Geonuclear has developed, in cooperation with the Atomic Energy Commission, a set of detailed plans utilizing nuclear explosives for an underground engineering experiment called project Rio Blanco. The overall objective is to prove the commercial feasibility of using nuclear explosives to recover commercial quantities of tightly held natural gas in the Piceance Basin."
