Once you install your pump out pit you can install a gate valve and channel water around creek the creek bed where you install damm should have a cross seal trench to prevent water from runnig under damm. Rember a creek bed can run 4 feet below surface. Once you hit dry dirt pack clay in a cross ussally triple the width and same on the lateral
Good Luck
