FERC Project 2246 Relicensing
Thursday, November 10, 2010
YRDP Relicensing uses a mix of historical gaged flows and synthetic accretions.
NBB accretion inflow is 33% of total NBB Inflow
Englebright accretion inflow is 35% of total
Englebright inflow (excluding NBB inflow)
Flow1 = (Area1/Area2) * (Precip1/Precip2) * Flow2
Differences between mass balance and synthesized flow are explainable by potential variations in gage data:
Colgate PH gage variations
Looked at effect of potential gage variations at:
Colgate gage- as described for NBB
(FERC nameplate is 315 MW)
