Ride along with South Metro Dive 31 to a simulated water rescue incident at Cherry Creek State Park for a reported kayaker underwater. This Dive Alert 3 response was a surprise to all of the crews who responded non-emergent to the reservoir and operated as if a real drowning victim needed to be rescued. The collaboration with Colorado Parks and Wildlife was invaluable to SMFR personnel and better prepared our organizations for real emergencies. Remember, life jackets save lives.
