Lower San Joaquin River Committee Briefing of New Melones Project and Vernalis Modeling Dan Steiner January 3, 215 1
Task Demonstrate effects of changed flow and salinity in the San Joaquin River upon Vernalis flow and salinity and the operations of the New Melones Project. Approach Flow and quality conditions of the San Joaquin River at Maze provided by WARMF. NEWMOM worksheet model used to simulate the river reach between Maze and Vernalis, and the operation of the New Melones Project on the Stanislaus River as affected by differing mainstem flow and quality conditions. Comparison of model results. 2

New Melones Project Operation In general, the actions and circumstances of the Planned bundle develop changes in flow and quality in the San Joaquin River upstream of the Stanislaus River confluence. At times these changes occur when the New Melones Project operation is providing specific releases to comply with the D1641 Vernalis water quality objective. If the change in upstream San Joaquin River flow and quality requires less water from the Stanislaus River to comply with the downstream water quality objective, New Melones would release less water for that purpose. However, such a reduction in release may be countered or limited by a need to release for a flow or quality requirement such as the D1641 Vernalis flow requirement or Stanislaus River instream dissolved oxygen objectives. During periods when Vernalis flow objectives affected the New Melones operation, changes in flow due to Planned bundle actions and circumstances would cause a corresponding change in New Melones releases, again potentially countered or limited by other release requirements. 11
