Lake Management Planning

De Pere ● Madison

Onterra, LLC was created in 2005 to offer objective lake management planning services at a reasonable cost.  The firm is head-quartered in De Pere, WI, while a second office and limited lab are located in Madison, WI.  Onterra provides a variety of lake-related services ranging from science-based diagnostic/feasibility studies to comprehensive lake management plans consisting of aquatic plant inventories, stakeholder education, watershed and water quality analysis, and implementation plan development.

Every planning project led by Onterra is created upon a foundation of science and objectivity.  The structure built on that foundation is composed of stakeholder participation and education.  As a result of this combination, a realistic and implementable management plan can be created that meets the needs of the lake and the folks that care for it alike.

Quality planning through science, experience, and service.


Our Projects

Onterra has worked on lakes throughout much of Wisconsin for a variety of clients, including lake associations and districts, municipalities, the Wisconsin DNR, US Environmental Protection Agency, US Army Corps of Engineers, and the US Fish and Wildlife Service.  Our primary focus is to assist lake groups in developing a realistic management plan for their lake.  Often times, we also assist the lake group with the implementation of portions of that plan.
