Volunteers plant trees to stabilize a river after dam removal

An obsolete dam was removed last year in an effort to help trout populations
More than a dozen volunteers planted willow trees October 25 to stabilize a river bank outside of Eleven Mile Canyon. The project comes two years after a dam was removed from the river, which significantly lowered the amount of water, but also allowed trout to swim upstream, producing more quantity and diversity of offspring. The dormant willows will then have all winter to establish its roots.

This is what used to be the site of a dam which helped, contain water that was, pushed o to Colorado Springs.
But, that is long gone.
And in the interest of a healthi as well as, fish and the riparia the dam was, removed in its entirety and this whole area was restored Willows, particularly coyote, wi are highly beneficial for banks that have been disturbed.
Like this site where you remove and you've created a new bank or And then once you get the willow established, they are like a sponge so they can soak up water and hi At the same time, they can recycle nutrients.
And they also filter, toxins that may be in wa Today what's happening is, we're willows stakes so that we can plant them This particular portion of the South Platte is water that gets supplied to Denver.
And so the, the cleaner the water, the better in the scheme of things.
And what we're doing is that we're punching holes in the riverbank to get down to the water tabl and put these cuttings in there, and then we'll backfill them with, dirt and gravel.
And as such, they'll have a wint to slowly grow a root.
So by spring they should be, budding and leaf Just by virtue of having the dam the trout are able to move up an some 30 miles of river now.
So we expect that these trout wi They'll spawn in different area they'll spawn with different tro And we'll see a greate genetic diversity in these trout And that ultimately leads to a healthier population.
With the dam removal you basically restore to stretch and with that comes various bene including, bank stability the cleaner water and a healthie what becomes very clea is that once you establish willo and then other plants come with it and the bank stabilizes.
