Duluth Trout Streams Urban Watershed Restoration and Protection
Event-based Stream Sampling in Northeastern Minnesota
Determine pollutant concentrations and annual loads of nutrients and suspended sediments by intensively sampling streams during different hydrologic regimes (base flow, storm events, spring runoff).
Long-Term Aquatic Conditions to Inform Delisting Efforts on the St. Louis River
St. Louis County Rainy River Headwater Lakes, 2014-2015
The Minnesota Pollution Control Agency (MPCA) Surface Water Assessment Program is funding this effort to collect field and water chemistry data for 3 lakes within the Rainy River Watershed west of Ely, MN. The results of water quality analyses will be a critical addition to efforts to identify short- and long-term trends of response to impacts such as urbanization, agriculture and forestry practices, invasive species introductions, atmospheric deposition, and climate change.
St. Louis River Area of Concern Paleolimnology
One of the action items in the St. Louis River Remedial Action Plan (RAP) Update 2013 is to assess the eutrophication criterion in order to make local recommendations for removing this beneficial use impairment (BUI) to the Area of Concern.
GLEI II - Indicator Testing and Refinement
The GLEI-II project will focus on wetland near shore conditions of the Great Lakes, and consists of five tasks: 1) Refine coastal ecosystem indicators from previous monitoring programs through calibration against updated landscape/land use information within the entire Great Lakes basin, 2) test the temporal and geographic integrity of existing Great Lakes indicators, 3) test and compare analytical techniques to cross-calibrate indicators from concurrent monitoring programs, 4) evaluate cost-effectiveness of indicators, 5) implement a data collection, analysis, and reporting system, as well as a map of baseline conditions for the Great Lakes basin based on historical and current monitoring information.
Great Lakes Coastal Wetland Monitoring
To assess the biotic condition of all the major coastal wetlands of the Great Lakes, United States and Canadian shorelines.
North Shore Superior Lake and Stream Water Assessment
To collect field and water chemistry data from eight Northern Lakes and Forest (NLF) Ecoregion lakes and three NLF streams between May 2013 and September 2014 for the purpose of determining surface water quality.
