#Runoff news: Twin Lakes should fill next week — more water for the Roaring Fork River

From Aspen Public Radio (Elizabeth Stewart-Severy):

Water levels on the Roaring Fork River are expected to rise next week as Twin Lakes Reservoir reaches capacity.

Officials at the Twin Lakes Canal Company expect the reservoir to fill between Tuesday and Thursday next week. That means that the 625 cubic feet per second of water that is typically diverted to the Front Range through a tunnel on Independence Pass will instead flow down the Roaring Fork River.

That, in addition to peaking snowmelt, means flows on the river could nearly triple next week. It is expected that the North Star Nature Preserve will flood. This is healthy for the wetlands.

Officials at the Bureau of Reclamation said releases from Ruedi Reservoir into the Fryingpan River will decrease over the weekend. This reduces the risk of flooding at the confluence of the Fryingpan and Roaring Fork in Basalt. Ruedi Reservoir is about 80 percent full.

From TheDenverChannel.com (Oscar Contreras):

Medano Creek is now approaching what’s called “surge flow,” a phenomenon where creek water flows in waves across the sand.

The combination of a sufficiently steep channel, a sandy creek bottom and plenty of flowing water only exists in a few places on Earth, according to the spokesperson, “and Medano Creek is considered the best place in the world to experience surge flow!”

Because of the unusually cold and wet conditions in May, peak flow is occurring a little later than average this year, the spokesperson said.

You can follow detailed creek conditions and forecast flow on the National Park Service website.
