Trophic State Index - Management Targets

Management Targets

Often, the desired Trophic Index differs between stakeholders. Water-fowl enthusiasts (e.g. duck hunters) may want a lake to be eutrophic so that it will support a large population of waterfowl. Residents, on the other hand, may want the same lake to be oligotrophic, as this is more pleasant for swimming and boating. Natural Resource agencies are generally responsible for reconciling these conflicting uses and determining what a water body's trophic index should be.
