Table C - De Sum
*E vaporation is paid by City of Longmont under separate SWSP in conjunction with water court case no. 09CW271
** Water use for concrete batching to come from well permit no. 13410 -F -R (WDID 0207073)
* ** Lagged Dewatering Depletions, as shown in the table, are from past dewatering operations that have ceased. All
other current dewatering operations were considered to have reached a steady state condition.

Depletions
The depletions resulting from evaporation, water lost in product, dust control and concrete
batching are shown in Table C below:
A stream depletion model using either the Glover method, or Stream Depletion Factor (SDF)
method was used to calculate the lagged depletions to the river. The Glover method uses four
aquifer input parameters for each site as follows: 1) X - distance (ft) from centroid of exposed
ground water to river, 2) W- distance (ft) from the aquifer boundary through the well to the river
channel, 3) T- transmissivity of the alluvial aquifer (in gallons per foot/day) between the well and the
river, and 4) S- specific yield - 0.2 was used for all wells. The parameters used in the model for
each site are listed on the next page in Table D.
