Environmental and Water Quality Operational Studies. Environmental Guidelines for Dike Fields.
Abstract
These environmental guidelines for dike fields consist of environmental objectives, design procedures, and river-specific examples of currently employed environmental features that can be used to maintain or increase fish and wildlife habitat diversity. Design, construction, and maintenance of dikes can alter the water depth, current velocity, and substrate composition to increase habitat diversity of US Army Corps of Engineers waterway projects. Features that can be incorporated into dike fields to increase diversity are notches, low-elevation dikes, rootless dikes, and minimum maintenance practices. Other potential techniques include dredging to remove sediment, disposing of dredged material within the dike field, relocating old notches, placing additional rock, adding artificial reefs, and building control structures in side channel closure dikes. Two case studies--one on the Missouri River, one on the lower Mississippi River--of river response of dike field construction are presented. Aquatic habitat requirements of representative vertebrate species and of aquatic invertebrates in general are given in appendixes.
