Notes:
[1] Based upon analysis of Lester - Attebery Ditch daily diversions between 1950 - 2006, pro -rated based upon percent ownership of each of the three water rights totaling 9.1 cfs.
[la] Ditch Loss equals 10% of diversions, [1] x 0.1.
[lb] Farm Delivery equals diversions minus ditch loss, [1] - [la].
[2] Surface Runoff equal to 20 percent of farm delivery; [lb] x 0.2.
[3] Based upon Modified Blaney - Criddle analysis with an elevation adjustment for the Grisenti crop mix of primarily alfalfa, and climate records from the Canon City weather station from 1950 - 2006,
computed in StateCU.
[4] Historical irrigation on Grisenti Ranch averaged 89.4 acres between 1950 and 2006, based upon aerial photo delineation and consistent with information provided by Mr. Grisenti.
[5] CU results from StateCU analysis.
[6] Equals [lb] - [2] - [5].
[7] Lagging factors based upon a steady -state Glover analysis using the following parameters: D (weighted) = 700 feet, T = 40,000 gpd/ft, and s= 0.087.
[8] Lagged Groundwater Return Flow equals annual amount To Groundwater distributed monthly using the Glover Factors, [6 Total] x [7 Monthly].
[9] Total Return Flow equals Surface Runoff + Lagged GW Return Flow, [2] + [8].
[10] Historical Stream Depletion equals Historical Diversion less Total Return Flow, [lb] - [9]; if positive, else zero.
[11] Historical Stream Accretion equals Total Return Flow less Historical Diversion , [9] - [1b]; if positive, else zero.
[12] Based upon Phase I and partial Phase II mining removing 45.4 acres of irrigated acreage, [10] x 45.4/89.4.
[13] Based upon Phase I and partial Phase II mining removing 45.4 acres of irrigated acreage, [11] x 45.4/89.4.
