When two bodies of water, or tributaries, join together, they transform into something bigger and stronger. This is why our monthly donors are our Tributaries, people who come together to make our rivers stronger and healthier. For $5, $10, $20, or more per month, you can become a Tributary and sustain your rivers.

Become a Tributary



Besides helping out Colorado’s rivers, what else is special about our Tributaries? They receive:




Access to exclusive events






Exclusive updates to keep you in the loop about our work and Colorado’s rivers







Day trips to amazing field sites with our rock-star team






Recognition on our website and in our annual report



Tributaries are also included in our myRiver Balance program! myRiver Balance is a way for people to balance their water use by returning the amount of water they use each year to Colorado’s rivers and streams, through a contribution to Colorado Water Trust.

This means, that your donated dollars each month will help balance your annual water use and go directly toward the purchase or lease of water for rivers. 

Is your buisiness interested in giving back to Colorado’s rivers?

Colorado Water Trust Tributaries are not only individuals, but also local businesses who give back to their rivers on a monthly basis.
