A field study was conducted at West Okoboji Lake near Arnolds Park, Iowa to study transport of fluid resulting from wind forcing on summer stratification. A tracer was injected at the boundary of the lake and surveyed on four separate occasions over a period of three days. The Lake number was less than 10 during the first day of the tracer study. Evidence from three approaches supported the existence of V1H1 and V2H1 modes. Three methods showed that the vertical diffusivity was on the order of 10-6 m2 s-1. From the tracer surveys, the distance traveled offshore and velocity of the tracer was approximately 900 m and 0.8 cm s-1, respectively, with dispersion as the dominant transport mechanism. The horizontal eddy diffusivity was estimated from the horizontal tracer distribution to be between 0.2y10-1 m2 s-1 and 4y10-1 m2 s-1. There was no evidence to support boundary mixing or intrusions.
