Watershed Management


Responsibilities for water managers continue to grow with each passing year, moving them further into the public spotlight while new guidelines and regulations present unprecedented challenges.

HEI has worked alongside water boards and watershed districts throughout the Midwest and Great Plains for nearly five decades. We understand the people behind these organizations, their strengths and needs, and the work they do.

We are proud of the long-term partnerships we have created with water boards and the obstacles we have overcome together.

Our many services include:
