        Rick Hartson sends the following events for all of calendar year 2011. 
        The site was operating during 2011, but not registered in PTAGIS until 2012.

        January 21, 2011 at 18:20:  Issue with CR1000 and flashcards is resolved 
        and data collection begins again in full. Fows at mouth of watershed are 
        above 500 cfs. Expect detection efficiency to be considerably reduced from 
        normal operational levels.
        
        January 20, 2011: Flows at mouth of watershed have dropped below 300 cfs. 
        Detection efficiency has likely improved to near optimal conditions.
        
        January 22, 2011: Flows increased to over 500 cfs at watershed mouth, but 
        are currently declining to below 300 cfs. Expect periods of reduced detection 
        efficiency today.
        
        February 28, 2011: Flows have remained low since late January and we expect 
        high detection efficiencies.
        
        March 11, 2011: Flows increasing and have approached 500 cfs at watershed mouth. 
        Expect detection efficiencies to decline.
        
        March 29, 2011: Flows have remained between 400 and 800 cfs at the watershed 
        mouth since March 11. Expect reduced detection efficiencies during this period. 
        
        March 31, 2011: Flows rapidly increasing, approaching 2000 cfs at the watershed 
        mouth. Expect considerable reductions in detection efficiency. 
        
        April 2, 2011 at 17:54: Flows increased to near 2500 cfs at watershed mouth. 
        Damage to antennas has occurred, probably occurred overnight on April 2, 2011 
        when flows rapidly increased. Antenna 2 had no current. Antenna 1 had reduced 
        current and was not detecting tags efficiently. Turned off power to MUX. No data 
        collection until we can replace damaged equipment.
        
        October 6, 2011 at 14:36: Data collection begins again after spring washout of 
        antennas. 2 NMFS designed PVC encased antennas at mouth of Webb Creek are turned 
        on.  Both antennas span the width of the stream in low flows and may miss about 1 m 
        on either side in high flows.  Read range is 18 inches for the upstream antenna a
        nd 18 inches for the downstream antenna.  Both antennas are 10 m long. The original 
        downstream antenna (ANT 2) washed away. We kept the original upstream antenna 
        (was ANT 1, now ANT 2) and installed an additional antenna upstream (called ANT 1).
        
        December 23, 2011 at 16:36: Data collection stopped. Lost power to MUX. Apparently a 
        power outage caused the circuit breaker to flip and the batteries stopped charging. 
        Low flows this fall have likely resulted in high detection efficiencies before loss 
        of power halted operations.
