Worldwide, people benefit greatly from the irreplaceable services provided by freshwater lakes, such as drinking water, recreation, and fisheries. However, human activities in lake catchments contribute to eutrophication and the growth of harmful algal blooms that threaten the very waters upon which people depend. This degradation can generate incentives for behavioral change. For example, lake associations can initiate citizen-driven actions to protect and improve water quality, but will this action come in time and focus on the key drivers of water quality.

This project examines the linkages between land-use decision making, fate-transport of nonpoint source pollution to lakes, lake water quality, the effects of water quality on property values, and the community responses that stimulate changes in land uses. In three lake catchments that vary in the intensity of agriculture, forested land and residential development we build the linkages from land use to water quality to identify the key drivers of lake water quality.

CNH-L: Linking land-use decision making, water quality, and lake associations to understand human-natural feedbacks in lake catchments

A harmful phytoplankton bloom in Lake Mendota, Wisconsin, one of the Virginia Tech project team's study sites. Blooms such as these, which occur throughout most of the summer in Lake Mendota, severely degrade water quality. Photo credit: Cayelan Carey

Worldwide, people benefit greatly from the irreplaceable services provided by freshwater lakes, such as drinking water, recreation, and fisheries. However, human activities in lake catchments contribute to eutrophication and the growth of harmful algal blooms that threaten the very waters upon which people depend. This degradation can generate incentives for behavioral change. For example, lake associations can initiate citizen-driven actions to protect and improve water quality. But will this action come in time? And will it focus on the key drivers of water quality?

This project examines the linkages between land-use decision making, fate-transport of nonpoint source pollution to lakes, lake water quality, the effects of water quality on property values, and the community responses that stimulate changes in land uses. In three lake catchments that vary in the intensity of agriculture, forested land and residential development we build the linkages from land use to water quality to identify the key drivers of lake water quality.

The insights from the three focal catchments will inform the understanding of human-natural system dynamics across thousands of lake catchments spanning the northeastern and midwestern U.S. An understanding of the relationships between and lake water quality and land-use policies will be leveraged to support science-based monitoring, advocacy and volunteerism to develop effective programs to protect and enhance lake water quality.
