Little Kickapoo Creek (LKC) is a low-gradient, third-order perennial stream with headwaters in Bloomington, IL. The objective of this study is to characterize vertical one-dimensional (1-D) flux rates in the top 150 cm of the streambed, test the viability of a heat tracing method in a low-gradient area, and determine the relationship between stage and 1-D vertical flux rates. In 2009, six wells were installed along the thalweg of the stream in a 25-meter stretch spaced at 5-meter intervals. Each well recorded temperature at five separate depths logging at 15-minute0 intervals from February 2009 to March 2010: 30, 60, 90, …
