SWSP ACCOUNTING PROJECTION
Rocky Ford East Pit
(all values in acre -feet unless otherwise indicated)
Notes: Shaded months correspond with projection data, non - shaded months correspond' with actual data.
[1 ] Total maximum exposed groundwater surface area in the pit.
[2] Total gravel ruined below the groundwater table as reported by Valco. Active mining has completed. Production values correspond to remaining inventory being sold.
[3] Well pumping measured with totalizer. The pump has been removed and no more pumping will occur.
[4] Required evaporative replacement based upon the following: Equals ([1'1- 17.4 ac x 4.02 R x monthly %.
17.40 ac = pre -1981 exposed groundwater surface area (does not require augmentation)
3.85 feet = annual net evaporation rate at the site
[5] Water in mined gravel is 4:-u by weight of the gravel produced. Equals [2] x (1/1359 afhon of water) x 4 %.
[6] Well pumping cunverted to acre-feet Equals [3]/(325,851 gaUuf).

[ 10] River transit loss applied to excess Canon City and Oil Creek Ditch Credits that are used to augment depletions at Rocky Ford.
[III Excess Canon City and Oil Creek Ditch credits used at the Rocky Ford site (reduced by transit loss). Equals (Canon City Table [14]) x (100% - [10]).
