A man was cited for three counts of fourth-degree assault and reckless endangerment after allegedly colliding his fishing boat with another vessel Saturday morning on the Columbia River near Hammond.

Marlin Larsen, 74, was driving a fiberglass 31-foot Bayliner Trophy up river with two other passengers — Adam Forrester, 20, and Timothy Forrester, 52 — just after 8:30 a.m. It then collided with an aluminum 20-foot Weldcraft, soon after that boat’s operator — Christopher McMahon, 45 — and two passengers — Bryan Maess, 47, and Roni Durham, 57 — jumped into the river to avoid the impact.

McMahon and the two passengers had been trolling for salmon. Boaters in the area pulled them from the river as the Clatsop County Sheriff’s Office and U.S. Coast Guard responded. All three were treated for minor injuries at Columbia Memorial Hospital.

Larsen is a Roseburg resident who owns the Harborview Resort in Hammond. Prior to Saturday’s incident, he had been cited for speeding in Oregon eight times since 1983.

The Sheriff’s Office is still investigating the incident.
