What are potential flow paths through the limestone under the spillway? What does that mean?
This particular item refers to the capability of water to move – or find pathways – through rock. In this case, the limestone present under the spillway. The concern is that during pool events above 1600 feet — a pool level never before reached in Gathright’s 30-year history — water could potentially find and exploit pathways through the limestone under the spillway.
