*4.2. Evaluating Potential Baseline Changes: The CALFED Years (1996–2005)*

The CALFED years, nominally spanning 1996 through 2005, reflect a period of change from the early years of the MWQI program. Prior to 1996, most of the work done by the program was completed in response to water agency concerns over the contaminants in the source water of the Delta and focused on existing problem definition and possible solutions. With the 1994 Bay-Delta Accord among state and federal agencies with management responsibilities over the Delta, and expansion of the interagency CALFED process [16], the MWQI program expanded its scope to address potential changes in land use, water storage, and conveyance. A summary of program activities during this era is provided below.
