Yellowstone National Park will see its first park-wide fishing closure on all rivers and streams since 2007, the Associated Press reports. The closure will prohibit fishing from 2 p.m. to sunrise the following day. Fishing on Yellowstone Lake and other lakes in the park is still allowed, within current regulations.
In a news release, park officials say water temperatures surpassing 68 degrees, and historically low streamflows caused the closure. High temperatures can cause stress on cold-water species like trout, and catching those fish can increase chances of mortality. The closure will remain in place until further notice.
