Carvins Cove Reservoir, California


 
 

Carvins Cove Dam

  • 80 foot tall abutment built at Carvins Creek Falls near Salem, Virginia
  • The dam was completed in 1928, but the actual reservoir was not finished until the mid 1940's, and filled in May,1946
  • Max depth:      70 ft (23m)
  • Surface area:   1100 acres (2.5km)

 

Carvins Cove Oxygenation System 

Facilities
  • 4,000 feet (1250m) of diffuser in 2 lines
  • 4-tons/day oxygen delivery capacity
  • Design flow rate 40 SCFM

 
 
Raw water / plant operation
