Summary

These data were collected in support of a multi-agency effort to evaluate the feasibility of using carbon dioxide to create a barrier and prevent upstream passage of invasive fish through navigational locks. The auxiliary lock at Lock and Dam 14 on the Mississippi River near Pleasant Valley, Iowa, was chosen for a field-scale trial of the carbon dioxide barrier to be conducted in 2018. In preparation for this trial, the mixing in the lock chamber during routine operations and the fate and transport of lock water released to the pool downstream was studied using a dye tracer. In June 2017, the U.S. Geological Survey (USGS) performed two injections of Rhodamine WT dye into the auxiliary lock chamber as the lock was filled. The dye was [...]

Purpose

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.
