Lake Powell striped bass facts Striped bass Stripers were stocked into Lake Powell in 1974. Average fish caught in Powell range from 3-8 pounds.
Striped bass are native to the east coast of North America.
They were a main food item for the Plymouth colonists in 1623. Populations have been established in 279 inland waters, most notably the TVA and Colorado River impoundments. Most reservoirs are continually restocked, because natural reproduction is not adequate. Spawning occurs in the spring when the water temperature push above 50 degrees. Ocean fish move into freshwater to spawn, and may migrate as far as 100 miles.
