Pioneer Farm bank erosion study
Riparian grazing allows cattle free access to streams, but may accelerate erosion by the removal or trampling of vegetation. This study measured stream bank erosion, channel morphology, and stream substrate through seven experimental intensive-rotational pastures. It also evaluated the use of photo-electronic erosion pins (PEEPs) for measuring bank erosion in this type of geomorphic setting.
Bayfield tributaries geomorphic assessment for restoration
Lake Superior tributaries in Bayfield County, Wis., have accelerated erosion and sedimentation influenced by changing land use, steep slopes, erodible soils, and flashy runoff. This project assessed the geomorpology of five tributaries, identified problem areas, and assessed rehabilitation alternatives and watershed management strategies specifically related to the rehabilitation of brook trout.
NAWQA Surface Water National Fixed Network Site Status and Trends
As part of the USGS National Water Quality Assessment (NAWQA) program the USGS MIWSC operates a stream gage and routinely collects water quality samples at the Clinton River at Sterling Heights, MI. station. Water is analyzed for sediment, nutrients, major ions, and a suite of 271 different pesticides. Information obtained from this site is compiled with information from other National Fixed...
Avian Botulism in Distressed Great Lakes Environments
Botulism outbreaks occur within the Great Lakes and often result in significant bird die offs. It is believed that Clostridium botulinum is the reason for these die offs and the trophic pathways that this organism travels are of interest to understanding its place within the food web. The GLRI Avian Botulism Project is investigating six different matrices: sediment, Cladophora, invertebrates...
