Raising a dam - RCC Stay informed Project review and permitting

Denver Water understands that our work is likely to cause disruptions for residents and recreationists in the area. We are committed to being a good neighbor by working closely with stakeholders to ensure safety and maintaining open, two-way communication channels throughout the project. We will continue to listen to concerns and seek community input to identify ways we can minimize inconvenience to the local community where possible.  

Over the course of the Gross Reservoir Expansion Project, we have developed a variety of channels to share information and receive community feedback. We will continue to update information on this website, including regular updates about construction activities onsite, project documentation and contact information. 

Project updates will be shared on the project's Google MyMap and via email. Don’t forget to subscribe to and update your preferences for our e-newsletter!  

Project staff is also available to meet one-on-one either online or in-person and during regular office hours. You can schedule an appointment or send us comments or feedback through the contact page, by calling the project hotline (303-628-6348) or by sending us an email at
