Dozens of all-time heat records have been broken in California and Nevada as a several-day heat wave relentlessly bakes the West.
YELLOWSTONE, Wyo. – Fishing at Yellowstone National Park will be curbed starting Monday to protect native and wild trout fisheries amid the recent heat wave.
Temperatures at the nation’s oldest park reached the low 90s this week, according to the National Weather Service. This comes after a heat dome covered much of the West last week, causing temperatures to skyrocket.
This had a ripple effect on water temperatures in Yellowstone, which have exceeded 68 degrees, according to park officials. They added that the flows on a number of park rivers, streams and creeks are low.

“These conditions are extremely stressful to fish and can be fatal,” the NPS said.
