Nov 9: The U.S. Army Corps of Engineers (USACE) released for public comment three draft Aquatic Pathway Assessment Reports for the State of Indiana: Eagle Marsh, Loomis Lake and Parker-Cobb Ditch. The purpose of each report is to evaluate key evidence to estimate the likelihood of an aquatic pathway forming and the possibility of aquatic nuisance species (ANS) using it to reach the adjacent basin, as part of the Great Lakes and Mississippi River Interbasin Study (GLMRIS).
In 2010, a temporary barrier was built to prevent adult Asian carp transfer at Eagle Marsh. However, the Eagle Marsh assessment report found that Eagle Marsh remains a high risk potential pathway due to the probability that viral hemorrhagic septicemia virus (VHS) could spread across the basin divide. USACE GLMRIS Program Manager Jack Drolet said, "There has been significant progress on Eagle Marsh. Because this was identified early on as a potential Asian carp transfer site, the Indiana Department of Natural Resources built a temporary barrier, and the GLMRIS Team began to evaluate potential permanent control options. That report will be available soon and will provide opportunity for stakeholder input."
The ANS Controls Report that identifies options and technologies that may be available to permanently prevent the inter-basin transfer of ANS during flooding events at the Wabash – Maumee basins connection at Eagle Marsh near Fort Wayne, IN will be released for a 60-day comment period November 16. Comments for the three draft Indiana reports will be accepted beginning Nov. 9, 2012 and will close Dec. 7, 2012.
