creation of small dams and
restoration of areas that are degraded wetlands.
Different designs for compensation areas have been tried to improve the quality of the created wetlands. The differences in the environment from southeastern South Dakota to northwestern South Dakota could mean that different designs based upon the environment of the area might be needed. Analyses of the designs used by the Department in regard to quality of wetlands created has not been done.
Other states have developed criteria for wetlands design. Guidelines that could point out dos and donts of wetlands compensation and design methods by physiographic regions of the state could ease the problems associated with wetland mitigation.
