Lake Restoration
Eutrophication, driven by increased nutrient loading, results in the degradation of a lake resource for a variety of important uses. There are two approaches that can improve lake resource quality:
-
Reduce the amount of external loading from the watershed (nutrients, sediments, oxygen demand, and organics)
-
Increase the assimilative capacity of the lake (ability to accept external loads while expressing good resource quality).
Our lake restoration work involves quantitative watershed management as well as management of the internal structure and function of a lake (increasing aerobic capacity, trophic level biomanipulation, nutrient inactivation, etc.). We develop a specific restoration plan to accomplish identified resource management goals.
Fishery Habitat Restoration
Many lakes have lost cold water habitat required for cold water fish and as refuge for algae-eating zooplankton animals. Loss of suitable habitat may only occur for a few weeks each summer, but eliminates whole populations of desirable organisms year-round. We have developed cost-effective methods for restoring and preserving suitable cool water habitat so trout and herbivorous zooplankton can thrive.
