Abstract: Aeration was measured and modeled at 28 navigation dams in the upper Ohio River basin. Dissolved oxygen (DO) deficits upstream and downstream of the dams, water temperatures, and flow rates were measured under a variety of low‐flow, high‐temperature conditions. The DO deficit downstream of each dam was modeled as a linear function of the other variables. The DO deficit upstream was found to be a consistently significant predictor of DO deficits downstream of a dam. Inclusion of temperature and flow rate generally did not significantly improve the statistical aeration models. The field data show that supersaturation can occur at some dams; this means that the reaeration ratio
