This letter is in response to your application of February 1, 2005 requesting a substitute
water supply plan for a sand and gravel pit owned by Raindance Aquatic Investments, LLC
(Applicant) and operated by Connell Resources. The required fee of $1,343 for the substitute
water supply plan has been paid.
This plan describes the proposed water uses through April 2007 for this new mining
operation. The proposed plan anticipates a maximum year net depletion of 27.45 acre-feet for
up to 0.2 acres of exposed groundwater surface as identified in the attached Table 2. Because
this is a new mining operation, no groundwater was exposed within the permit boundary prior to
January 1, 1981.
This current plan anticipates dry mining of the Raindance River Gravel Pit by dewatering.
The operator proposes to continuously dewater and dry mine the site. The operator proposes to
install a clay liner concurrent with mining as a means to create an off-channel reservoir for water
storage upon reclamation. The operator has obtained a Division of Minerals and Geology bond to
cover the cost to line or backfill the pit in the event the operator walks away from the project
and/or allows the dewatering operation to discontinue.
You have provided a monthly breakdown of the maximum annual depletions totaling 0.5
acre-feet of evaporative loss from a maximum of 0.2 acres of exposed groundwater, 4.8 acre-
feet of water used and consumed for dust control, and 22.1 acre-feet of water lost with the
mined product. Lagged depletions for the terms of this approval are as follows: 13.62 acre-feet
for 2005, 23.32 acre-feet for 2006 and 5.16 acre-feet for 2007 as identified in the attached
Table 3. No phreatophyte credit has been applied to this plan.
The mining operation is located more than 100 feet from the Cache La Poudre River. The
applicant has provided a monthly schedule of lagged depletions to the river system resulting from
the operational losses at this site. Due to the lagged timing of depletions, replacement obligations
will continue after active mining at this site has been completed and subsequent substitute water
