587.1 Reservoir at spillway level and begins to overflow into the Esopus Creek downstream. Downstream flooding is reference to the Mount Marion gage MRNN6.
586.5 This basin is nearly full and only 0.25 inch runoff is needed to start spilling over into the Esopus Creek downstream.
585.79 This basin has capacity for only about 0.50 inch of runoff before it will overflow into the Esopus Creek downstream.
585.1 This basin has capacity for only about 0.75 inch of runoff. It is getting close to full.
