Such tanks are filled with water to balance a ship's loads. Unless the water is treated before it is emptied into foreign waters, it can introduce foreign organisms into the water that may become established and compete with native species, causing untold ecological and economic damage. USGS scientists are taking up the challenge of dosing, mixing and testing cost-effective treatments in such large tanks that will kill the organisms but render the water safe for discharge.

The USGS Glen Canyon Adaptive Management Working Group took a trip in August from Glen Canyon Dam to Lees Ferry on Friday, August 31, 2012. This spot at Four Mile (four miles downstream from the dam) is where a lot of people fish: There were fishermen that day that claimed to have caught about 25 fish!
