Fishhook Park on the Snake River will be without water service next year while the water system is upgraded.
The park, which is 18 miles east of Burbank, will remain open during the normal season of May 18 through Sept. 4, 2018, while the work is being done.
The park’s drinking water is contaminated with nitrates, a chemical that is particularly hazardous to pregnant women and babies, causing blue baby syndrome.
The Army Corps of Engineers has had to alert visitors to the poor water quality in recent years and ask them to provide their own drinking water.
“That’s not what people expect when they go to a full-service park and campground, so we’re correcting it before it gets worse,” said park ranger Heather Geertsen.
