Thanks to those that had positive input. Stage one complete. Got some good data on 2 spots. Back up to finish up a couple more in a week.

Details are TBD. The following are some primary ideas. The 2 dimensional area of the spring could be measured by placing temporary bobbers in areas where a subnormal temp is indicated. To measure stratification and volume, color coded bobbers could be used correlating to the feet off bottom an abnormal temp is received. This will be the 3rd dimension and will result in the info necessary to calculate volume of the cold water. CFS is anticipated to be a bit more difficult to determine. One idea discussed at this time is displacing the cold water and measuring the amount of time it takes for the prior cold temp at the site to be reached. I am open to ideas.

Interest arises from a geology class. Course selected to fill a science requirement in the liberal arts curriculum at small, private college. Please note, I am NOT a geology major.

Thanks for the positive response in PM.
