In 2008, Minnesota voters passed the Clean Water, Land, and Legacy Amendment to increase the state's sales tax; a good portion (33%) of the resulting funds is meant to "protect, enhance, and restore water quality in lakes, rivers, and streams." A post on the Minnesota Public Radio website evaluates whether these new resources have had a positive impact. Jeffrey Peterson, director of Consortium member the Water Resources Center (WRC), notes: "The available data. . . are mixed and difficult to summarize." He refers to water quality variations and fluctuations around the state; the time lag between implementation of new practices and measurable results; and the need to expand the number of watersheds being monitored. Peterson took over the top spot at the WRC in August, 2015 after 15 years in the Department of Agricultural Economics at Kansas State University.
