Navigation facility components susceptible to zebra mussel infestation include measurement systems, raw water systems, chamber gates, spillway gates, culvert valves and racks, emergency closure and dewatering gates, concrete surfaces, and navigation aids. This section details each component of concern and applicable zebra mussel control methods.
The migration of zebra mussels from the Great Lakes is traceable from observations at projects on navigable streams. The Corps of Engineers operates nearly 250 lock and dam projects nationwide. A significant number of projects are operated separately along the St. Lawrence Seaway, the New York Barge Canal, and various smaller facilities. Infestations at these projects has been an early indicator of operations and maintenance problems as well as an information source regarding remediation.
