Since stock ponds are not flat bottomed, the simplest way to monitor water volume is with a depth-capacity curve showing the total volume stored at various water levels throughout the season. You can use this publication to develop a pond curve, if one is not available for your stock water pond. You'll be walked through the steps needed to develop a pond curve - including data collection, instructions on using an ANR online app to develop your curve, how to determine volume.
