The Sut­ter Bypass remained inun­dat­ed with flood­wa­ters and is still inac­ces­si­ble to safe­ly work.  The UC Davis research team remained ready to begin sam­pling for recruit­ment of nat­ur­al occur­ring fish­es (wild or hatch­ery-ori­gin) and mon­i­tor­ing water qual­i­ty con­sis­tent State and Fed­er­al agree­ments to oper­ate the project.  

The UCD Team used this peri­od of time to per­form work rel­a­tive to the hatch­ery-ori­gin fish being reared at the UCD lab which was going well and on sched­ule.  The pur­pose of adding lab-reared fish to the project will be to eval­u­ate cer­tain aspects of the draft man­age­ment prac­tice, includ­ing move­ment of fish thought the rice checks and over­all in-field sur­viv­abil­i­ty.  This is done by insert­ing Pas­sive Inte­grat­ed Transpon­der (PIT) tags in these fish to mon­i­tor their move­ment as well as sein­ing the fields to quan­ti­fy tagged and marked fish.
