SJR Flows at Stockton and Head of Old River Russ Brown, ICF Jones & Stokes SJR DO-TMDL
Stockton Flow and DWSC DO • Stockton flow is always less than 50% Vernalis • Stockton flow is reduced by about 5% Exports • DO deficit (below saturation) was reduced from about 6 mg/l to about 1 mg/l as the flow increased from 0 cfs to 2,500 cfs • DO deficit is reduced by 1 mg/l for each 500 cfs of flow; the DO was >5 mg/l at 1,500 cfs • How will this change with reduced ammonia loads? • Will a model provide better predictions?
