But they are much more than the meager flows the streams have in fact been getting, and much more than agricultural and urban diverters would willingly let go.
During the nine years the board has been working up to this moment, a parallel process has been dragging along: negotiations among water suppliers, state agencies, and some environmental groups to produce Voluntary Settlement Agreements that could help fish while minimizing legal and political battles.

Some novel and promising ideas were sketched, which the board promised to study as it turns its attention to the Sacramento drainage and the Delta itself.
