The required fee of $257.00 for this <br />substitute supply plan has been submitted (receipt no. 3641463). The supply plan was most recently <br />approved on August 29, 2007. <br />SWSP Operation <br />The Bromley Lakes Pit is approximately a 140-acre pit located between the South Platte River <br />and the City of Brighton, consisting of Cells 2 and 3 which are owned by the City of Brighton and are <br />being mined for the completion of water storage. Cell 1 now known as Kenneth Mitchell Lake has <br />been lined and the liner was approved in April 2007. The City of Brighton obtained a storage water <br />right in the Ken Mitchell Lakes (which includes Cell 1, 2 and 3) in case no. 1998CW018 (2006CW222). <br />The City of Brighton is now responsible for any water depletions at Cell 1. Ready Mixed is storing their <br />excess Fulton Ditch water in Kenneth Mitchell Lake for replacing winter depletions at Bromley Lakes, <br />North Tower Pit and the Ready Mixed Pit No.1 sites. <br />This plan seeks to replace depletions resulting from the evaporative losses and dust control at <br />the Bromley Lakes sand and gravel mine. The proposed replacement sources are consumptive use <br />credits from Fulton Ditch shares owned by the Applicant and water stored in the Kenneth Mitchell Lake <br />(formerly Cell 1 of the Bromley Lakes Pit) and a lease from the City of Brighton will make replacement <br />during March and April 2010. <br />Depletions <br />The total exposed surface area at the Bromley Lakes pit is 44 acres within Cell 2 and 3. Ready <br />Mixed stopped dewatering Cell 3 in July 2008 thus no dewatering is provided or sought under this <br />SWSP. Consumptive use of water at the property for the plan period consists of 117.3 acre-feet of net <br />evaporation from an exposed water surface area of 44 acres and 2 acre-feet of water used for dust <br />control, totaling 119.3 acre-feet (Table 1A, Column 8). <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
