Newly Hatched Invasive Grass Carp Found in Maumee River, Ohio
A genetic analysis conducted by the U.S. Geological Survey recently confirmed that larval, or newly hatched, fish collected from the Maumee River during the summer of 2018 are grass carp, one species of invasive Asian carps that threaten the Great Lakes. The Maumee River is a tributary to Lake Erie.

Tree Swallow GLRI Story Map
This Story Maps accompanies 4 peer-reviewed publications to provide a convenient and useful tool to access the information contained within these four peer-reviewed publications. The tree swallow data are easily visualized on a landscape scale, or more detail can be obtained by drilling down. These data are being used by States and EPA in their Beneficial Use Impairment (BUI) assessments. ...

Tracking phosphorus and sediment sources and transport from fields and channels in Great Lakes Restoration Initiative priority watersheds
A multi-agency, integrated series of studies were initiated in 2017 under the Great Lakes Restoration Initiative (GLRI) by the U.S. Geological Survey, U.S. Forest Service, and the University of Minnesota to quantify the source, downstream travel time, and storage of particulate-bound phosphorus and sediment in agricultural tributaries to the Great...

Delineation of tile-drain networks using thermal and multispectral imagery—Implications for water quantity and quality differences from paired edge-of-field sites
As part of the Great Lakes Restoration Initiative, paired edge-of-field sites were established in high priority subwatersheds to assess the effectiveness of agricultural management practices. One pairing was in Black Creek, a tributary to the Maumee River and Lake Erie. These fields were paired because of similarity in soils, topography, and...
Williamson, Tanja N.; Dobrowolski, Edward G.; Meyer, Shawn M.; Frey, Jeffrey W.; Allred, Barry J. Assessing the impact of site-specific BMPs using a spatially explicit, field-scale SWAT model with edge-of-field and tile hydrology and water-quality data in the Eagle Creek watershed, Ohio
The Eagle Creek watershed, a small subbasin (125 km2) within the Maumee River Basin, Ohio, was selected as a part of the Great Lakes Restoration Initiative (GLRI) “Priority Watersheds” program to evaluate the effectiveness of agricultural Best Management Practices (BMPs) funded through GLRI at the field and watershed scales. The location and...
