The stench from thousands of dead fish rotting on the shoreline has effectively ended the summer season at the Hyrum State Park and reservoir, says Superintendent Bruce Olsen.

Olsen said this week the park usually is busy every day this time of year, but last month the reservoir was treated with the chemical Rotenone to kill fish infected with infectious hemotopoitic necrosis, or INH.The virus has affected fish in the Little Bear River drainage downstream from a Paradise fish farm that also has been poisoned and disinfected.

But a mixup between the state Division of Wildlife Resources, which conducted the poisoning project, and the state Parks and Recreation Division has left the fish where they lie.

"No one has bothered to clean up the dead fish, and the smell is extremely offensive," Olsen said.

He said he'd been led to believe the DWR would have the fish cleaned up, but that a day after the treatment, the people assigned to the project pulled out.

Tim Provan, assistant director of the DWR, admits there was a lack of communication between his agency and Parks and Recreation.

"Our division rarely treats waters managed at state parks, and each agency thought the other was cleaning up," he said.

While officials resolve the clean-up issue, Olsen said there's also a revenue problem.
