EXHIBIT G (Cont'd) <br />' Page 4 <br />February 16, 1978 , <br />problems with the Ferguson wells develop which can be attributed to the <br />' ~ mining operation, it is recommended that Mobile Premix Company provide <br />water in quantity and quality equivalent to the historic well characteristics. <br />B. Letter dated July 12, 1977, from Adams County Commissioners to <br />Consolidated Rock Company. <br />The Adams County Commissioners requested a response from Consolidated <br />• Rock Company (now Fiobile Premix Company) as to how drainage from First <br />Creek would be provided outletting into the South Platte River. <br />' Historically, a drainage outlet for First Creek was provided as shown <br />on Exhibit No. 2. First Creek flows from east to west under Brighton <br />Boulevard via a 14" X 24" box culvert and thence under Fulton Ditch via <br />an 18 inch culvert. It is at its outlet from under Fulton Ditch that <br />most of the major alterations to first Creek's drainage pattern have taken <br />place. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />Prior to the existance of the present gravel pit, First Creek outletted <br />into Bull Seep Ditch as shown on Exhibit No. 2. After Consolidated Rock <br />Company commenced its mining operations, the creek was diverted north <br />along the east edge of the pit into the Young Ditch as shown on Exhibit <br />No. 3. Both of these routings eventually discharged First Creek water <br />into the South Platte River. <br />As was pointed out previously in this report, Mobile Premix Company should <br />provide a 12 to 15 inch culvert outlet into Young Ditch and maintain natural <br />flows into Bull Seep Ditch. Therefore, it is recommended that First Creek <br />be routed into the gravel mine lakes as shown on Exhibit No. 4. First <br />Creek drainage water will thereby find its way to the South Platte River <br />via Bull Seep Ditch and/or the Young Ditch as it historically has done. <br />' LHW/kt <br /> <br /> <br />••~,,.,,,,,,•~~ Sincerely yours, •• <br />•;.`•••G~ H.
