Denver Water’s system is at 96% of capacity after the very wet September

From the Summit Daily News (Joe Moylan):

On Tuesday, Jim Lochhead, CEO and manager of Denver Water, met with the Summit Board of County Commissioners during a workshop in Frisco. Lochhead provided the commissioners with an update on Denver Water’s service system following September’s historic flooding on the Front Range.

Although Lochhead said the system worked “perfectly” in the sense that service to customers was not interrupted and no dams were breached during the flood, Denver Water sustained $15 million to $20 million in damage to roads, exposed conduits and one of its gravel pits located near the South Platte River.

Despite the damage, and Denver Water’s commitment to assist its partner communities in recovering from flood damage, Lochhead said there is a silver lining to take away from the event. According to the most recent reports, Denver Water’s reserves, which consist of 15 fully or partially owned reservoirs across more than 4,000 square miles of watershed in eight counties, is at 96 percent capacity.

Update: Stacy Chesney sent a correction via email:

The story states: “Gross Reservoir near Boulder, for example, increased in capacity by 26 acre-feet as a result of the flooding, Lochhead said.” As a result of the storms, Gross Reservoir gained 7,600 acre-feet of water and went up in elevation by 19.6 feet. This equates to an increase in storage of about 26 percent.

Gross Reservoir near Boulder, for example, increased in capacity by 26 acre-feet as a result of the flooding, Lochhead said. Gross Reservoir’s capacity is 41,811 acre-feet, according to Denver Water’s website.

Lake Dillon, Denver Water’s largest reservoir at 257,304 acre-feet, also is reporting some of its highest seasonal levels in history, Lochhead said.

But the increased water capacity presents a handful of short-term challenges, Lochhead said, including spring water management should the High Country receive dense snowpack this winter. All of its water comes from mountain snowmelt, according to the Denver Water website.

More important, however, is the fact that the recent increase in capacity does little to ease future water shortage concerns as Denver, the Front Range and the rest of Colorado continue to grow in population…

Lochhead’s idea is fairly simple — encourage upward, rather than outward growth along the Front Range and the challenges surrounding water conservation will begin to remedy themselves.

For example, a single-family home with a garden in Denver uses the same amount of water as a four-unit building constructed on a similar-sized lot, he said. However, much of the growth on the Front Range is sprawling away from urban centers; meeting growing water needs is only exacerbated by the current trend of purchasing or building single-family homes on quarter-acre lots.

It’s a type of growth that is unsustainable not only in terms of water use, Lochhead said, but also in terms of providing services, such as transportation and energy delivery, because property tax revenue cannot meet the needs that come with a sprawling population.
