Fish Passage Solutions
Construction and development activities affect aquatic habitats. They impact the hydraulic conditions of a natural waterway and can block fish from migrating to and from the ocean. We work to minimize these impacts by implementing innovative engineering designs that facilitate safe, timely, and effective fish passage in estuaries and inland watersheds.
