Dike 14

The Dike 14 Confined Dredge Material Disposal Facility (CDF) was the site of an avian botulism outbreak in 1986. In addition to waterfowl mortality, the outbreak created a major public relations problem for the U.S. Army Corps of Engineers.

AES worked with the Corps by developing a pilot project to install plant materials prior to the disposal operations so that vegetative cover would rapidly appear as the CDF dewatered after disposal operations. AES selected specific native vegetation to make the CDF unattractive to shorebirds, wading birds, and waterfowl susceptible to avian botulism.

AES identified strategies for alleviating the avian botulism outbreak and designed unique equipment and planting strategies to alter the environment. We converted the open, exposed mud flats, and pools to a dense grass, sedge, and bulrush habitat that attracted only birds that were not vulnerable to avian botulism.

Designated as an Audubon Important Bird Area, Audubon Society recommended that the highest levels of conservation be applied to Dike 14.

In 2002, a broad-based group of environmental, research, and social organizations recommended Dike 14 be designated a nature preserve. AES conducted environmental testing and risk assessment studies to promote that effort.
