This project will determine pre- and post-settlement nutrient trends from sediment chronology, fossil diatom assemblages, and from sediment profiles representing human history in the region (i.e., at least 150 years). Project activities include sample collection; sample preparation; diatom analysis; database creation and management; and data interpretation. Sample cores will be taken on the Lake of the Woods in five major bays (i.e., Four-mile, Muskeg, Sabaskong, Little Traverse, and Big Traverse) in the southern basin.
With a perceived increase in the frequency and intensity of cyanobacterial algal blooms in Lake of the Woods (LOW), there has been an increased effort to collect information about the nature of algal blooms, nutrient concentrations and sources of nutrients to the LOW.
This project will apply science to identify viable and priority wetland restorations and rehabilitations that will deliver sustainable water quality benefit, along with flood storage and habitat benefits. Decision tools will be developed to assist with selection of restoration projects.
This project will provide lab analyses and interpretation required for 2012 wild rice field survey. The 2012 lab analyses will be merged with the 2011 field survey data and determine what additional work, if any, is needed during the 2013 field season.
The MPCA is currently collecting additional information needed to evaluate the 10 mg/liter wild-rice-based sulfate standard and has received funding through legislation passed during the 2011 Special Session to implement a wild rice research plan and contract with scientific experts to further understand the effects of sulfate on the growth of wild rice. The goal of this project is to determine responses of wild rice to sulfate and the products of geochemical transformations of sulfate.
