Fifty‐one ground water samples collected in a losing reach of the Platte River were analyzed for alkalinity, dissolved oxygen (DO), dissolved organic carbon (DOC), and for the ∂ 13 C values of DOC. Ranges in concentrations were 24.8 to 109 mg/liter, 0.0 to 5.5 mg/liter, 0.5 to 4.8 mg/liter, and −15.6 to −25.4 ‰ for inorganic carbon, DO, DOC, and ∂ 13 C, respectively. The concentrations of these constituents are primarily associated with land use and well depth. Carbon isotope fractionation can be useful in determining sources of organic carbon to the ground water.
