Stop Asian Carp Act

Stop Asian Carp Act - Directs the Secretary of the Army, acting through the Chief of Engineers, to study the watersheds of the Illinois, Chicago, and Calumet Rivers, including their tributaries, that drain directly into Lake Michigan to determine the feasibility and best means of implementing the hydrologic separation of the Great Lakes and the Mississippi River Basins to prevent the introduction or establishment of populations of aquatic nuisance species between the Great Lakes and Mississippi River Basins through the Chicago Area Water System (CAWS) and other aquatic pathways.

Requires the study to: (1) include options to address flooding, Chicago wastewater and stormwater infrastructure, waterway safety operations, and barge and recreational vessel traffic alternatives; and (2) contain a detailed analysis of the environmental benefits and costs of each option.

Directs: (1) the Secretary to carry out this Act at full federal cost; and (2) the President, or the Council on Environmental Quality as a designee to the President, to oversee the study to ensure its thoroughness and timely completion.

Requires the Director of the United States Geological Survey (USGS), in cooperation with the Director of the United States Fish and Wildlife Service, to: (1) monitor and survey all waters that connect to the Great Lakes Basin or could connect to it due to flooding, underground hydrological connection, or human-made diversion to identify additional threats that could allow Asian Carp to enter the Basin; and (2) prioritize each threat and help identify means to impede the passage of Asian Carp to the Basin.
