DMAN1968: You are correct, the spillway was not designed to build marsh. In fact, during each opening, most sediment is deposited south of the ICG Railroad (first railroad from river), then some noticeable sediment deposits between ICG and KCS Railroad (second railroad from river.) When the spillway has settled,after this next opening, go take a ride in the spillway from River Road to US 61, and unless it's different from every other time it opened, you will see what I'm talking about. The previous opening of the spillway water scoured a hole 26 feet deep under railroad trestle at the lake near center of spillway (it was on the news railroad shut down for repairs). Every time spillway is opened there are algae blooms in lake from excess nutrients in river water.
However, if as bullcoon suggested, the east spillway levee is opened north of the hurricane protection levee diverting river water through LaBranch wetlands, nutrients will be filtered from the water in the marsh where it's needed before entering the lake lessening impact on lake. Facts, opinions, who cares? We know what happens to the lake each time the spillway is opened. Maybe it's time to try something different.
