concluded that the post- mining pumping rate of the north well was 32 gpm. See May 27, 2009 <br />letter from Aggregate Industries. Aggregate believed that - with a new pump, and tying the north <br />well and the south well together - the Rodmans could approximate the 50 gpm original capacity <br />of the original well on the property. Id. Nevertheless, based on its belief that the post- mining <br />pumping rate of the north well was within 3 gpm of the 1993 well that it replaced, Aggregate <br />declined to provide any new pump to the Rodmans. Id. Bill Rodman was never fully satisfied <br />by this response. <br />The data from Aggregate's pump test is attached. Regarding the 30 gpm rate described <br />for the north well, per conversation with Christy (spelling ?) of Quality Well, the gentleman <br />named "Said" may have told Aggregate that the rate was 32 gpm because there is a 2 gpm <br />margin of error in the meter readings at the pump test. The data also shows that the south well <br />pumped 15.5 gpm "under pressure." Christy commented that, without pressure (as was the case <br />with the pump test on the north well), the south well's yield would probably have been 17 gpm. <br />Note that separately the wells achieved a combined rate of at least 45.5 gpm. <br />This pumping rate was achieved at a time when the La Farge / Martin Marietta gravel pit <br />had apparently been dewatering at a rate of 1,200 gpm for many years. See July 20, 2004 letter <br />from Applegate Group, Inc. to the State Engineer's Office. <br />In the course of compiling this data, it was realized that the 15 gpm pumping rate in <br />permit 055880 -F (issued for the north well in 2001) is erroneous. Both the pump test when the <br />well was constructed and the 2009 Aggregate test show a rate higher than 15 gpm. Discussions <br />concerning this matter were had with Linda Korf in the Greeley Division Engineer's Office and <br />Joanna Williams in the Denver State Engineer's Office. It appears that the State Engineer's <br />Office would entertain a request to increase the pumping rate, but they now require a water court <br />decree in order to issue a permit for one well as an alternate point for another well. Apparently, <br />they did not have such a policy back in 2001 when 055880 -F was issued. Therefore, the <br />Rodmans have decided to file a water court application seeking a decree that will authorize each <br />well as an alternate point of diversion for the other, with both wells still under the augmentation <br />plan of Cache La Poudre Water Users Association. <br />History of Rodman Well Pumping <br />Page 2 of 2 <br />
