The Des Moines Fire Department practiced water rescues Wednesday at Gray’s Lake.
Usually the crews do ice training when the ice is pretty thick but on this occasion the crews went to work practicing on thin ice.
Officials say they want to make sure rescuers are comfortable in all situations.
To practice, one firefighter acted as the victim in one scenario. The crews also had to pull buckets of rocks out of another hole in the ice.
“The biggest thing is stay off, if you’re not sure if the ice is safe, stay off of it,” advises Captain Steve Brown. “If you do see somebody go in call 911 and try and use a branch. Never go out after somebody.”
The crews were out training in the cold and wind for several hours.
