  1. San Joaquin River Water Quality Modeling- A Beginning SJR-DO TMDL Technical Work Group Presentation Russ Brown- Jones & Stokes January 20, 2005

  2. San Joaquin River Data Atlas-modeling without data is folly • Initially Part of the DWSC and SJR WQ Modeling Contract with HydroQual (and Jones & Stokes) • Upstream Modeling Task will Update (2004+) and Expand (missing data sources) • Includes 1984-2003 (20 years) of daily/grabs • Annual Master Excel Files • Comparison Files with Basic Annul Graphs and simple calculations

  3. Data retrieval can be hard work –with some spinning of wheels

  4. San Joaquin River Flows & EC-daily water and salt budgets

  5. -let me see the data so that I can think about it!

  6. - Check compliance with WQ objectives

  7. San Joaquin River Algae & Nutrients- green and brown water

  8. Suspended Solids and Turbidity-dead or alive?

  9. Stockton DWSC DO- tracking the seasonal and diurnal variations

  10. City of Stockton RWCF Loading

  11. Initial Modeling of SJR Water Quality – its all about inputs

  12. SJR Salt (EC) Budgets- Measured and Simulated

  13. SJR Hydraulic Geometry- surface area, volume, depth, and travel time

  14. SJR WQ Modeling- baby steps towards comprehensive adaptive management framework • Extend to tributary dams and Salt & Mud Sloughs and San Luis Drain • TSS & turbidity-seasonal inputs & settling • Temperature and light effects on algae • Diurnal growth and grazing of algae • Algae pigments, VSS, and BOD at Mossdale • Loss of algae from Mossdale to DWSC? • Old River diversion gates- DWSC flow and algae • DWSC DO management by oxygenation?
