The river below the Palisades Dam is roaring because the flow has been raised to just under 20,000 cfs (about the same at Heise and near 14000 cfs at Lorenzo). Tributaries to the the reservoir above are in run-off modes and discolor its upper end. This is all from run-off in progress after a higher than normal snowfall winter. Therefore expect high flows in the river below the dam for a while yet. Try streamer and rubber leg patterns DEEP in slowest water.
