USGS Water Study to Use Red Dye in Toll Gate Creek
Printer Friendly versionPrinter Friendly


The U.S. Geological Survey (USGS) Colorado Water Science Center will conduct a dye-tracing study for Toll Gate Creek in Aurora, Colo., from July 9 to August 5. During this time, non-toxic red dye, rhodamine WT, will be released into the creek and will be monitored as it flows downstream.

Rhodamine WT, the fluorescent red dye used in this study and commonly used in other hydrologic studies, is non-toxic and safe for the environment. The dye will be released at various locations which lie to the north of Mexico Avenue and to the west of Buckley Road, and monitored at downstream locations by USGS hydrologists.

The study will provide estimates of the time it takes for water in the creek to flow through Aurora. These estimates can be used to understand the movement of contaminants that can be introduced to the stream either by design or as the result of an accidental spill. The study is part of ongoing work by the USGS and the City of Aurora.

Information on USGS studies of water resources in Colorado is available at the Colorado Water Science Center Web site.
