YOSEMITE NATIONAL PARK, Calif. (CBS13) — Two men drowned Wednesday morning after they were swept off a bridge by high water levels, authorities said.

The two men were crossing the Wapama Falls Footbridge near the Hetch Hetchy Reservoir at about 8:30 a.m. when water was flowing over the bridge, and the current pulled both men off the bridge.

The footbridge provides a close vantage point to the Wapama Falls, but in years that see a heavy snowpack followed by hot temperatures, fast snow melt can raise water levels until the current actually flows over part of the bridge.
