Drowning at Marshall Lake in Boulder County

Boulder County, Colo. - On Saturday, October 10th, 2015, at approximately 4:55pm, the Boulder County Sheriff’s Office Communications Center received a report that a male party had been trying to swim across Marshall Lake and had not been seen within the last approximately 6-7 minutes after going under the water. Marshall Lake is located near the intersection of South 66th Street and Coal Creek Drive in unincorporated Boulder County, Colorado.

Responders from the Boulder County Sheriff’s Office, Rocky Mountain Fire, Louisville Fire, Boulder Emergency Squad, Longmont Emergency Unit, and Front Range Rescue Dogs were dispatched to the scene to assist. Volunteer Victim Advocates with the Boulder County Sheriff’s Office also responded to the scene to assist in providing support to the family members and witnesses who were present.

While rescue resources were on the way, boaters found the 58 year old male and pulled him out of the water. Resuscitation efforts including CPR and the use of an AED were attempted on scene by medical personnel and the victim was transported to Avista Hospital. Additional efforts to revive the male at the hospital were ultimately unsuccessful and he was pronounced dead.

At this time, the incident appears to be accidental; however the incident is still under investigation by the Boulder County Sheriff’s Office and the Boulder County Coroner’s Office. The Coroner’s Office will make a determination of the cause and manner of death once their investigation is completed.

The Boulder County Coroner’s Office will release the name of the deceased once they have confirmed that all family members have been notified.
