This data was used for the analysis in the paper "Assessing factors related to Walleye stocking success in the midwestern United States". This data includes stocking records of walleye from the Midwestern United States and subsequent evaluations of these stockings as provided by state agencies. Additionally, attributes of lakes such as size (depth, area), trophic state, and temperature are included to evaluate factors that relate to walleye stocking success. A second copy of the data is included that relies on imputation to fill in data gaps. Methodological processes are outlined in the associated paper.
