Sediment supply and transport report available

SFPUC consultants McBain & Trush have produced a preliminary sediment transport report for the Upper Tuolumne River between O'Shaughnessy Dam and Early Intake. The report is a first step towards characterizing the sediment transport dynamics of the upper river and developing a model that can be "gamed" to help assess the effects of future environmental flow recommendations for O'Shaughnessy Dam on sediment dynamics in the river.
