The watershed for the Saint is a lot bigger than Richland. I would guess if there is one it’s not accurate. The water level varies greatly depending on where the rain was, was it a fast downpour or a slow and steady. Even the time of year and vegetation matter. It got to 5.5′ above the bridge today and will probably be bridge level or thirties in the morning. If it were the dead of winter it might still be 2-3′ over tomorrow, heat of summer it might be below the bridge already. The only prediction that’s accurate is you’ll have more fun on Richland.
