Serving clients across the central United States, from South Dakota to Texas, the company combines sport-fish management expertise with knowledge of aquatic communities and ecosystem conservation. Its goal is to create healthy, sustainable fisheries tailored to each owner’s priorities, whether that means trophy fishing, family recreation, or restoring a more natural ecosystem.

BWO offers electrofishing surveys, fish population assessment and stocking, prey fish programs, habitat enhancement, aquatic weed control, water quality analysis and remediation, and bathymetric mapping. It also designs and installs aeration and destratification systems to improve oxygen distribution and address water quality challenges.
