Consider the Extremes of Our Reservoir Water level Experience in Recent Years
• 2009- normal year except for very high water as ice went out causing shore damage
• 2010- very little spring runoff and reservoirs did not fill until late July or early Aug.
• 2012- much lower than average water levels beginning in late May
• 2013 – very high spring and late fall levels from rainfall events.
• 2014 – 200%+ of normal snowpack, late ice out date, and very high spring runoff on River.
