Table 2
Debeque Gravel Pit SWSP - Projected Water Use and Stream Depletions during 2013 and 2014 Plan Years
I Deere & Ault Consultants, Inc.
(1) From Kirkland Construction. Projected for 2013 and 2014 Plan Years.
(2) Based on 4% water content by weight.
(3) From Kirkland Construction. Projected for 2013 and 2014 Plan Years.
(4) Net Lake Evaporation of 38.35 inches per year after consideration of effective precipitation (7.55 inches per year).
Adapted from Table 2, Column 5 of the 05CW076 Decree.
(5) For 2013 plan year, mining assumed to resume and pit is dewatered to 3.6
acre pond plus 2.0 acres of exposed water surface in dewatering system for 5.6 acres total
(6) (5) x (4), converted to acre -feet
(7) Pond volume dewatered in May and June (half each) to allow resumed mining Dewatering pumping causes lagged depletions and discharge to river is a credit.
Dewatering shut down in November for winter once call goes off. Refill assumed two - thirds in November, one -third in December
(8) From Table 3, Column 2 of the 05CW076 Decree for the 0.82 acres of phreatophyte area historically existing
under the original 3.6 acre pond
(9) = (2) +(3) +(6)
(10) From AWAS modeling.
