The current deliveries of Lake Meredith releases are via the Lake Meredith Outlet Canal, Holbrook Canal, Fort Lyon Storage Canal, and final discharging into the Arkansas River, . Rocky Ford Delivery System - a new delivery system from the Lake Meredith Outlet Canal to a location immediately upstream of the Rocky Ford Diversion Headgates, The Lake Meredith Outlet Canal, Holbrook Siphon and its current configuration would remain operational. The Rocky Ford Delivery System would be required to convey a maximum flow of 83 cfs to the canal's headgates. . Holbrook Delivery System - the Lake Meredith Outlet Canal would be rerouted to a location immediately upstream of the Holbrook Diversion Headgates or continue in its present form with greater flow delivery through the Holbrook diversion gate upstream of the Holbrook Siphon, The new delivery system to the Holbrook Diversion which would allow downstream senior water rights (Holbrook and Rocky Ford Canals) to divert water from their respective headgates. These two canal's water rights have an estimated revised total direct flow diversion of 1,083 cfs, The Holbrook siphon would not be required under the new delivery system and therefore would be abandoned, Based on a cursory engineering review, the Holbrook Delivery System alternative appears to be cost prohibitive and does not offer any significant advantage from the present delivery system, In addition, the current system historically has not diverted on a regular basis flow from the Lake Meredith Outlet Canal to the Holbrook Canal. At this time, no further investigation and analysis of this delivery system should be performed, URS Greiner Page 4
