Not necessarily preposterous, just 'cause it's unheard of? Although as far as I recall, it was either more like the dredging cut the river floor down to a softer layer that is now further eroded by the current, or the dredged channel itself allowed for enough flow to make an impact on lake levels (read tom qherinq's link). Depending on who's talking.
