'cause. . . WE'RE ALL DOWNSTREAM !

Water Quality Matters!

One of the most valuable resources in northern Colorado is water.

Water is a key to sustaining our way of living and our unique blend of urban areas, agricultural lands, and vast natural areas. Protection of water quality is paramount to ensuring that we don't degrade one of our greatest assets.

We Need Your Help

Larimer County needs your help to protect our limited, but valuable water resources and teach others to do the same.

Did You Know?

  • Stormwater runoff occurs after rain or snowmelt flows over the ground.
  • Stormwater can pick up trash, oil, dirt, and other pollutants as it travels.
  • Most stormwater flows untreated to streams, lakes and reservoirs.
  • Larimer County has a Stormwater Quality Ordinance that prohibits the discharge of pollutants into stormwater systems.

What you do affects everyone, particularly those downstream.

The effects are cumulative so it's important we all participate in protecting stormwater, and ultimately our drinking water, from pollutants.

Working Together

The Keep it Clean program is a partnership of Colorado communities working to implement a regional stormwater management program to enhance awareness of stormwater quality issues.

H2O Jo and his partner Flo are the mascots for the Keep It Clean program and we hope you come to associate them with the importance of stormwater quality.
