A Colorado man died in a boating accident Saturday afternoon at Lake McConaughy State Recreation Area, and a Colorado Springs woman was injured in the same accident.

According to reports gathered in the investigation, the woman fell overboard from a pontoon boat and her boyfriend jumped in to rescue her. He then had to be rescued by others on the pontoon and another boat nearby.

Kevin Kiesow, 53, of Colorado Springs was taken to Ogallala Community Hospital and later pronounced dead. Kim Lampe, 55, also of Colorado Springs, was admitted to the hospital and is recovering.

Nebraska Game and Parks Commission conservation officers responded to the report of an accident at 3:51 p.m. near Arthur Bay on the lake and found Kiesow being given CPR.

Wind speeds at the time were 15 mph with 20 mph gusts, making lake conditions rough.

The boat operator in the incident was not cited, and alcohol use is not suspected.

It is not known whether alcohol was a factor in Kiesow’s death.

No charges are pending at this time. A boat accident report will be completed and submitted to the Keith County Attorney for review.

Assisting in the response and investigation were the Nebraska State Patrol, Keith County Sheriff’s Office, and Keystone-Lemoyne and Ogallala fire and rescue departments.
