UPDATED FEBRUARY 10, 2022:

The search for a 70-year-old Wakpala man last seen on Lake Oahe near Mobridge on January 27, 2022 has been suspended until the ice melts on that stretch of the Missouri River.

Corson County Sheriff Alan Dale says they believe Clyde Oswald is most likely in the water as there is no indication he is gone and his green 1996 Ford Explorer is also missing. Dale says the search will resume when they can safely deploy boats to access areas they were unable to get to.

The Corson County Sheriff’s Office and Pierre’s Central Diver’s, LLC, conducted the search yesterday (February 9, 2022).

Central Divers owner Caleb Gilkerson, who volunteered his time and equipment for the research, says he primarily used a magnetometer (mag-na-tom-eter) on the surface of the water. It is a tool used in oil and gas fields to locate pipes and other related objects. He says remotely operated vehicles (ROVs) have also been used.

At one point, emergency responders from across the state assisted in the search. They include the South Dakota Highway Patrol Air Wing, Standing Rock Game & Fish, South Dakota Game, Fish & Parks, Bureau of Indian Affairs Police Department, South Dakota Highway Patrol, Civil Air Patrol, Carlson Services, Pierre Fire & Rescue, Pennington County/Rapid City Search & Rescue, Brown County Search & Rescue, Codington County Search & Rescue, Walworth County Office of Emergency Management, Corson County Office of Emergency Management and South Dakota Office of Emergency Management.

UPDATED FEBRUARY 9, 2022:

Pierre’s diving company is leading the search for a 70-year-old Wakpala man last seen on Lake Oahe near Mobridge on January 27, 2022.

Authorities believe Clyde Oswald is most likely in the water as there is no indication he is gone. Oswald’s green 1996 Ford Explorer is also missing.

Caleb Gilkerson, owner of Central Divers, LLC, volunteers his time and equipment for research. He says one complication is that they didn’t know exactly where to start.

A magnetometer is a tool used in oil and gas fields to locate pipes and other related objects. It is used on the surface, not under water.

High winds stalled the search for a few days, but Gilkerson says they hope to do more research today (February 9, 2022).

Gilkerson says another challenge of this research area is the depth of the Missouri River and unstable ice conditions due to abnormally warm temperatures.

Gilkerson says volunteers from across the state came to help.

Gilkerson and his team also led the search for Day County resident Amy Dougherty, who disappeared during a blizzard on December 23, 2020. They found her body on January 29, 2021.
