Hello everyone,

First off, I'm glad to report that presumed wayward Green Sturgeon has been detected again. It was detected further along its course at Colusa, our furthest upstream detector, on Thursday.

This week (3/8 at 10 AM to 3/13 at 1:30 PM non-daylight adjusted PST) our network detected five Green Sturgeon (2 new) and twelve White Sturgeon (3 new).

The Green Sturgeon detected this week included two new Green Sturgeon, one that was detected at the CCF and Tower Bridges on Wed 3/9 and Fri 3/11 at Knights Landing. The other was also detected at Friday at Knights Landing. The Green Sturgeon that was previously detected previously (3/6) at Knights Landing was detected 3/10 at Colusa, so also made it past Tisdale Weir. The final green sturgeon, previously detected 3/7 at Tower Bridge, continued upstream and was heard at Feather River Tuesday afternoon, Knights Landing on Wednesday and Thursday at Tisdale Weir.

Of the twelve White Sturgeon Detections, most (8) were detected solely at Lisbon Weir in the Yolo Bypass; however, there was one fish that appears to be heading back downstream and two that appear to be heading upstream in the mainstem of the Sacramento River. The fish that is heading downstream was previously heard 3/3 at Knights Landing was detected again at Knights Landing on Saturday 3/12 followed by Tower and Capital City Freeway (CCF) bridges the same day. A White Sturgeon detected for the first time in 2016 on the realtime network this week was detected at the CCF and Tower Bridges this Thursday. A returning White Sturgeon, previously heard 3/5 at Feather River, was detected 3/11 at Knights Landing. The final transmitter assigned as a White Sturgeon, detected a single time 3/7 at Colusa, was detected one more time on Friday at the same location.

Please contact me if you would like a tabular representation of this information. My next report, tentatively Thursday 3/17, may also include a graphical summary of 2016 information.
