Image: Thousands Evacuated Near Oroville Dam As Spillway Threatens To Fail

Oroville lake, the emergency spillway, the damaged main spillway, and the earthen Oroville Dam are seen behind the town of Oroville from the air on Feb. 13, 2017 in Oroville, California.

Almost 200,000 people were ordered to evacuate the northern California town after a hole in the emergency spillway in the Oroville Dam threatened to flood the surrounding area. 

The order was reduced to a warning on Tuesday, allowing residents to begin returning — with the caution that the condition of the dam that imperils the area could still change quickly.

A playground is submerged in flowing water at Riverbend Park in Oroville on Monday.

The Gold Rush town in the Sierra Nevada foothills, some 70 miles northeast of Sacramento, is nestled near the foot of the dam, which was completed in 1968 and at 770 feet is the nation's tallest. Houses and churches are perched on tree-lined streets near the Feather River. Old, ornate Victorian homes sit alongside smaller bungalows.

An orchard is turned to swamp land as floodwaters rise near Oroville on Monday.

The region is largely rural, with its politics dominated by rice growers, orchard operators and other agricultural interests. The region is dogged by the high unemployment rates endemic to farming communities. There are large pockets of poverty and swaths of sparsely populated forests, popular with anglers, campers and backpackers.
