Document Description
The Irvine ranch Water District (IRWD) intends to alter riparian habitat associated with San Diego Creek to manage riparian habitat in the San Joaquin Marsh that totals approximately 232 acres of the 356.09-acre San Joaquin Wildlife Sanctuary.

IRWD will conduct operation and maintenance activities outlined in "San Joaquin Marsh Operations and Maintenance Program."
