OtterTail biologists and ecologists are experts at the identification and delineation of wetlands and waters of the U.S.

Our project managers have combined to complete hundreds of U.S. Army Corps of Engineers Clean Water Act Section 404 individual and nationwide permits across Alaska and the lower forty-eight. From small but critical jobs requiring OtterTail’s well known rapid-response, to complex projects dependent upon multiple teams of biologists, OtterTail can be counted on to deliver.
