Denver Water: Moffat Collection System Project may benefit streamflows in South Boulder Creek

From The Denver Post (Charlie Meyers):

The South Boulder Creek situation involves a similar difficulty to maintain flows below the reservoir during those cold months when water generation is diminished and fish mortality occurs. Again, flow control by Denver Water is at the heart of the issue. The water provider currently agrees to maintain flows at seven cubic feet per second — provided this small watershed can produce even that minuscule amount. Help may be on the way in a Denver Water plan to boost West Slope diversion through the Moffat Tunnel, boosting storage in Gross Reservoir. A companion arrangement would allow the water suppliers for the cities of Boulder and Lafayette to utilize storage in the reservoir.

The potential to use this to enhance winter flows has caught the attention of Trout Unlimited, which long has sought a solution to the South Boulder Creek puzzle. “If we can use this increased storage to boost flows in the creek,” this would be something we could support,” said Drew Peternell, director of TU’s Western Water Project. But Peternell’s concern also extends to a larger matter, which is a Denver Water push to acquire more water from the upper Fraser River basin, then deliver it through the Continental Divide via its Moffat Tunnel complex.
