The purpose of this technical note is to summarize the zebra mussel densities found in Lock and Dam 7 at La Crescent, MN, in 1994. In addition, zebra mussel densities for 1991-93 and projected densities for 1995-97 at St Paul District locks and dams are discussed. In early December 1994, Lock and Dam 7, located at La Crescent, MN, was dewatered for major maintenance and repair. The dewatering provided an opportunity to collect information on the densities of zebra mussels on the lock floors and walls within the chamber.
