Juvenile survival of hatchery smolts Juvenile survival of hatchery smolts from release to Lower Granite Dam from release to Lower Granite Dam has ranged from 47.9% to 67.3% has ranged from 47.9% to 67.3% from 1999 to 2003 and was similar from 1999 to 2003 and was similar to natural smolts with the exception to natural smolts with the exception of 2001.of 2001.

Adult hatchery escapement has Adult hatchery escapement has ranged from 158 to 580 adults from ranged from 158 to 580 adults from 2000 to 2003.2000 to 2003.
