The September 2013 flooding along Leyden Creek resulted in several areas of damage, including overtopping and minor damage at Quaker Street and at the Croke Canal as a result of an emergency breach. Indiana Street experienced significant damage requiring culvert and roadway replacement. Several homes along Leyden Creek experienced flooding damage, including damage from shallow flooding that was observed throughout Cameo Estates both upstream and downstream of Alkire Street. Damages in the basin were less severe than they could have been without the quick thinking of local floodplain officials.
Leyden Creek is a left bank tributary of Ralston Creek with a total drainage basin of approximately 11.8 square miles. The Leyden Creek drainage basin covers lands in both unincorporated Jefferson County and within the City of Arvada. The Leyden Lake reservoir facility is located on Leyden Creek just upstream of Indiana Street and provides for significant discharge attenuation. Three major canals; Church Ditch, Farmers’ High Line Canal, and the Croke Canal, all cross Leyden Creek.
