Hardcopies of some reports are available by calling 209 946-6400 ext. 302.
All monitoring data are collected by STFWO and are available online through the IEP's BDAT data server.
Survival calculations from Chipps Island from 1976 to 1992 and 1993 to 2006 are available. Please note that these data are preliminary and subject to revision and correction. Survival indices prior to 1993 will be added as they are proofed for errors. Tagged recoveries by sampling location for each release between 1998-2002 are shown in maps.
The results of our studies have been shared in various arenas: workshops, IEP newsletter articles, gray literature in the form of annual reports, testimony to the state water resources control board and peer-reviewed journal and symposium articles.
