Turbidity in the Colorado River is dropping to levels previous to major wildfires and mudslides that roiled Glenwood Canyon in 2020 and 2021, Silt Public Works Director Trey Fonner said…Whenever loose rock and dirt unearthed from heavy rainstorms barrel into the Colorado River — the main source of drinking and agricultural use for Silt, Rifle and Parachute — sediment increases. The measurement is called turbidity…Turbidity levels rose after the Grizzly Creek wildfire consumed more than 32,631 acres within Glenwood Canyon in 2020 and after a rare, 500-year rain event in summer 2021 caused massive debris flows in the same area…

Middle Colorado Watershed Council Executive Director Paula Stepp said one of the ways to mitigate turbidity relies on new measurement devices installed up and down the Colorado River. With water quality monitoring stations established by the USGS in Garfield County, data collected from these sites are used to warn downstream users. Though Glenwood Springs’ primary water source isn’t the Colorado River, the city has water monitoring stations at Veltus Park on the Roaring Fork River and at the confluence of the Colorado and Roaring Fork Rivers near Two Rivers Park. Three other stations are located in South Canyon, Silt and Rulison…

Recently, Silt used $200,000 in American Rescue Plan Act funds to pursue an engineering study on how it can better its methods of pulling water from the Colorado River. That study concluded the city needed at least $30 million to not only combat turbidity levels but better serve its growing population. One way to pay for water and wastewater treatment improvements falls on the $1 trillion bipartisan infrastructure bill passed by Congress in November 2021.
