Jackson, P.R. and Lageman, J.D., 2018, Data associated with a dye tracer study in the auxiliary lock at Lock and Dam 14 on the Mississippi River near Pleasant Valley, Iowa, June 2017: U.S. Geological Survey data release, https://doi.org/10.5066/F7NS0T45.

The purpose of this dye tracer experiment was to examine the mixing within and downstream of the auxiliary lock chamber at Lock and Dam 14 on the Mississippi River near Pleasant Valley, Iowa. In addition, the dye tracer allowed net leakage rates through the lock chamber to be examined. This study provided planners in the USGS and U.S. Army Corp of Engineers (USACE) with valuable data to help understand potential challenges in treating the auxiliary lock chamber with carbon dioxide and the fate and transport of carbon dioxide-enriched water downstream of the lock. While the passive, conservative tracer may not behave exactly like a dissolved gas, it provides planners with a conservative estimate of potential carbon dioxide concentrations downstream of the lock which is required for permitting and environmental and ecological assessments.
