Dam foundation preparation, quarrying and site preparation activities at Gross Reservoir

Dam foundation preparation, quarrying and site preparation activities involving drilling and blasting are scheduled to begin at Gross Reservoir today, April 12. Please note:

• Blasting will only take place during daylight hours.
• Drilling and blasting activities are weather-dependent.
• These activities will take place near the dam and at the on-site quarry located near the former Osprey Point Boat Launch, as well as at on-site access roads and staging areas.

To ensure safety for all, crews will clear a safety zone prior to all blasting activities. This will result in some road- and recreation-related closures.

Prior to a blast, there will be a series of audible warning signals (shown below) to notify workers and the public to clear the area. If you are recreating at Gross Reservoir, please be aware of these signals and follow all instructions for your safety.

Blasting schedules will be posted along Gross Dam Road. Please see the project My Map for precise locations. We will also regularly update the My Map with blasting schedules and strongly encourage those planning to visit Gross Reservoir to check this resource prior to traveling to the area.

If you have questions, please email us at grossreservoir@denverwater.org or call 303-628-6348.
