Inc. and have also plotted the subdivision on USGS Quad maps (attached). <br /> Based on the infonnation provided to me by Bill Blatchley, I agree with Mr. Lindholm that the <br /> depletive impact on ISF rights is DeMinimis, Below is a brief summary of my findings. <br /> . According to Bill Blatchley, only one well will be constructed on the Troublesome Creek <br /> drainage with the remainder 20 wells on the Bear Creek drainage. <br /> . Me, Blatchley's estimates of total diversion for in-house use and turf-irrigation use for the 21- <br /> lot subdivision are 6.59 acre-feet per year and 0,9 acre-feet per year, respectively. <br /> . The following table shows diversions under each category, ISF right amounts, and percent <br /> injury to ISFs, <br /> Acre.feet/vear (%) <br /> Drainage In-house Irrigation Total Impact hnpact Cum Impact Cum Impact <br /> diversion diversion Summer Winter Summer Winter <br /> Bear Creck(94CW258) 6.280 0.857 1.137 0.106 0,174 0.115 0.191 <br /> Bear Creek(94CW259) 6.280 0,857 1.137 0.106 0.174 0.123 0.205 <br /> .
