The reservoir's waters are impounded by Vermilion Valley Dam (National ID CA00441), which was completed in 1954. The reservoir and dam are part of the Big Creek Hydroelectric Project.
HydrologyEdit
The reservoir discharges into Mono Creek, a tributary of the South Fork San Joaquin River. However, some of its water is diverted to Huntington Lake by means of the Ward Tunnel.
Vermilion Valley DamEdit
Vermilion Valley Dam is an earthen dam 4,234 feet (1,291 m) long and 167 feet (51 m) high, with 8 feet (2.4 m) of freeboard. Southern California Edison owns the dam.
RecreationEdit
Located in Sierra National Forest near the Pacific Crest Trail, Lake Thomas A Edison is the centerpiece of Vermilion Valley Resort and Vermillion Campground, which support boating, camping, fishing, swimming, canoeing, kayaking, and horseback riding.
AccessEdit
The lake is three hours by car from Fresno. Take State Route 168 east to Huntington Lake, head east on Kaiser Pass Road. The road crosses Kaiser Pass (elevation 9,175 feet (2,797 m)) and closes during the winter months. The United States Forest Service does not recommended it for buses, large motor homes, or vehicles towing trailers.
A ferry crosses the lake twice a day, linking Vermilion Valley Resort with the John Muir Wilderness trailhead and providing access to and from the John Muir Trail and Pacific Crest Trail.
NomenclatureEdit
The lake was named after American inventor Thomas Edison to mark the 75th anniversary of his invention of the incandescent light bulb. The dam was named after the valley it flooded, noted for its reddish soil.
