Officer Thom
Fischer pleaded guilty to a gross criminal misdemeanor and received a suspended jail sentence. The $ 1 million settlement included $ 745,000 in restitution to the Puyallup Tribal Fisheries and $ 255,000 in fines paid to Pierce County. In addition to the settlement with the Attorney General’s Office, Electron Hydro in 2021 was fined $ 501,000 by the state Department of Ecology for polluting the river.

On July 29, 2020, Electron Hydro, the company that owns and operates the dam, experienced an industrial accident in which crumb rubber debris was released into the
Puyallup River. Astro-turf used as part of a cofferdam broke loose from the HDPE liner and was spilled into the river. The company took

The flume and the railway were rebuilt in the 1940s, then again in 1985 on the original track. The original wood frames were replaced with over 12,000 steel frames, roughly four feet (1.2 m) on center. The flume is supported with over 6,000 bents. The flume is lined with 5.5 million board feet

The company also installed a rock wall in 2020 which was supposed to be removed in 2021. Electron Hydro was ordered by the court in
February 2024 to remove the center portion of the rock dam during the summer. The court ruled that the barrier harmed steelhead trout, Chinook salmon, and bull trout,

In early May 2023, a Pierce County
Superior Court Judge had approved a $ 1 million settlement in a criminal lawsuit brought by the state Attorney General’s Office over a 2020 spill of rubber into the Puyallup River during a construction project at the old wooden dam. The financial penalties for

A light railway line was built on top of the flume to shuttle maintenance workers and equipment. It is known as "the crookedest railway in the world," but it is not the only railway line with this claim.
