The estimated pit inflows from precipitation and <br /> groundwater and outflows due to pumping and evaporation indicate that this pit has been lined to the <br /> design standard referenced in the August 1999 State Engineer Guidelines for Lining Criteria for Gravel <br /> Pits. Meeting the design standard requires that all water Inflows and outflows for this pond must <br /> be accounted for on a monthly basis. <br /> Please call me if you have any questions. <br /> Sincerely, <br /> C�04k- C- ao'h <br /> Jana C.Ash, P.E. <br /> Water Resource Engineer <br /> CC: Fred Renner,Water Commissioner <br /> Jeff Deatherage, Water Resource Engineer <br /> David Nettles,Assistant Division Engineer <br /> Office of the State Engineer <br /> 1313 Sherman Street,Suite 818•Denver,CO 80203•Phone:303-866-3581 •Fax:303-866-3589 <br /> www.water.state.co.us <br />
