Monthly diversions for Roberts <br />Tunnel are presented in Table 2. <br />WATER RIGHTS <br />On the Blue River, the Roberts Tunnel water ri ght is junior to the storage rights of Green <br />Mountain Reservoir and the direct flow rights of the senior portion ( 1929 priority) of the <br />Continental-Hoosier diversion project. Dive rsions through the tunnel are influenced by the <br />downstream water rights for Green Mountain Rese rvoir, downstream calls from either the <br />Shoshone Power Plant or the Cameo area water rights, and the availability of water in other parts <br />of Denver’s system to replace out-of-priority dive rsions. Roberts Tunnel has direct flow water <br />rights for a total of 520.0 cfs absolute and 268.0 c onditional from the Blue River. Water diverted <br />through Roberts Tunnel is considered reusable water. As such, Roberts Tunnel water can be <br />used until the water is fully consumed.

When direct flow rights for Roberts Tunnel are <br />out-of-priority water stored under the Dill on Reservoir storage rights may diverted <br />through the tunnel. <br />On the Eastern Slope, diverted water may be st ored in reservoirs lo cated within Denver <br />Water’s South Platte Collection System incl uding Strontia Springs Reservoir, Chatfield <br />Reservoir, and Marston Reservoir. <br />Compact and Other Legal Considerations: <br />The following provides a general overview of the <br />key legal agreements that govern Roberts T unnel and the associated system.
