South Platte through Denver multi-year rechanneling


South Platte river work begins initial phase - Your Hub

"Latona said the work is needed because the volume of water in the river is decreasing but the channel size is the same."

“We have a 100-foot-wide channel carrying 2 inches of water. The amount of water we get in a normal year is more typical of a 40-foot-wide channel, so they are reshaping the bottom to concentrate all the water down into narrower sections,” he said.

I don't know exactly how I feel about this, but I don't think it's good. They have altered the river so significantly already, now they are permanently shrinking the channel.... what about rain and flash flood events? Won't the first big monsoon storm to hit the area wash away a good portion of the sediment they are using to narrow the channel?

Don 't have a strong feeling on this either way....for context : the Carson Nature Center is basically a riparian zone on one side of the river for 1/4 to 1/2 mile it has parking for access to the river and bike path that runs through it, a canoe livery, and small semi -museum.It is bounded by a park n ride /light rail access and shopping mall that it sits behind, a wetlands area on opposite bank (west) and to the south extending to C -470,to the north there is a lower middle class neighborhood on same side and high end homes and golf course on opposite side abutting the drops at Liegh Gulch.The area in question or just down stream gets used by local kids for tire swings into the river,tubing and partying, and dog walkers.Part of it is split rail fenced off and left natural with restrictions on dogs and bikes. It is maybe a hundred yards wide or less.This part is slow and deep .Above closer to the nature center is shallower must be where this is going on...If they narrowed it nearer Leigh Gulch making it faster and runnable at lower flows cool, except the drops are already well formed (#4 anyway) but too narrow for play

Wasn't it the South Platte that was original described as "a mile wide and a foot deep"?

There's a link on here (somewhere) that describes in detail the changes. I was bored, so I read it, front to back. Pretty interesting stuff actually. Only changing the first section to help the fishies. I don't remember the length, but it's pretty short--less than a mile as I recall, and that's pretty much starting at 470 and going north.
Basically, this section will be narrower, more curvaceous, and include riffles and pools and some other technical term for a bank that I can't remember.

That was the north Platte.
