ORDER GRANTING DWR’s MOTION TO ALLOW EXTRA RECORD EVIDENCETO EXPLAIN TECHNICAL 

TERMS AND COMPLEX SUBJECT MATTER (1:09-cv-407 OWW )

On October 19, 2009, the Court heard the Motion to Allow Extra Record Evidence to 

Explain Technical Terms and Complex Subject Matter filed by California Department of Water 

Resources and its Director, Lester Snow (collectively “DWR”) (Doc. Nos. 156; 345); 

Having fully considered the briefs and oral arguments submitted by the parties, and good 

cause appearing therefore, THE COURT HEREBY ORDERS: 

DWR’s Motion to Allow Extra Record Evidence to Explain Technical Terms and Complex 

Subject Matter Motion is GRANTED with respect to its request to present testimony by a DWR 

expert concerning DWR’s CALSIM II Simulation Modeling, because DWR made a threshold 

showing of the materiality of such testimony. 

The Court will allow a DWR expert to file a declaration explaining why comparing the 

historical data to CALSIM II -modeled data is not a scientifically acceptable practice (not “best 

available science”), and thus why the Service’s comparison of historic data with modeled data 

resulted in an inaccurate determination of the change in X2 attributable to future project 

operations. 

To establish that the Service’s comparison of data modeled by CALSIM II with actual 

historic data resulted in a materially flawed analysis, the Court will allow DWR’s expert to 

explain the CALSIM II modeling program, and explain the extent to which the modeling data can 

be appropriately used to assess the effect of future project operations on X2 and delta smelt 

habitat. 

This order is without prejudice to the Defendants and Defendant-Intervenors’ ability to 

object to the admissibility of the testimony in the declaration. 

Subject to further order of the Court, the declaration shall be filed and served on or before 

November 13, 2009. 

Dated: November 17, 2009 /s/ OLIVER W. WANGER
