    Warm Springs NFH decommisioned their adult ladder for the winter period on
    Dec. 3.  Upstream migrating fish in the Warm Springs River are able to
    pass Warm Springs NFH by swimming through a diversion channel.  During this
    time, PIT tagged fish will NOT be detected by the WSH adult ladder antenna
    array. The adult ladder is expected to be operational again in late January
    of 2011.

    Warm Springs NFH will be replacing their entire electrical panel between
    9/24/10 and 9/28/10.  Back-up generators will be used to power critical
    pumps during this time, however power will be shut off to the MUX and
    antenna array during this time.  There will be NO PIT DETECTION ability
    between 9/24/10 and 9/28/10.  Adult fish movement through the antenna array
    has been minimal, with only whitefish and suckers passing through between
    9/15 and 9/23.

    8/27/10  Power to MUX was off between approximately 12:30 on 8/20/10 to
    12:30 on 8/26/10 (corrosion on electrical receptacle).  Antennas were NOT
    DETECTING during this period, although interrogation files were being
    upload (power to computer was still on, interrogation files were "empty").
    Problem fixed at 12:39 on 8/26/10.  Site is now fully operational.

    08/16/10 Antenna array at WSH continues to operate with no known problems.
    Hatchery continues to trap all upstream migrating fish in catch ponds.
    Hatchery fish are culled out and wild (unmarked) fish are passed upstream
    of the hatchery.  Several PIT tagged mini-jacks have been detected swimming
    through ladder over several days.  Mini-jacks can swim in and out of
    hatchery catch ponds (weir and bars allow smaller fish through).

    03/12/10-Antenna 2 noise level high.  Water found in antenna.  Antenna
    still detecting (compared detections from antenna 1 to antenna 2 to
    verify) adult fish, however antenna removed and a temporary antenna
    installed.

    03/12/10-Communication between MUX and computer terminated ("send tag
    codes to comm 1" automatically turned off for some unknown reason, appears
    to be a MUX issue).  Files uploaded to PTAGIS between 11:17 on March 12 and
    14:24 on March 24 are empty.

    03/24/10-buffered data was downloaded from MUX and uploaded to PTAGIS on
    March 26 to replace "empty" files between March 12 and March 24.  No data
    gaps should exist.

    03/25/10-A new antenna 2 put into ladder.  Still has high noise but read
    range is fantastic.  Issue of DNS problems on FWS server have caused
    upload problems to PTAGIS, however files ARE eventually uploaded to PTAGIS.
    A fix is being investigated.

    CTWSRO and Oregon RFID did site visit to determine noise associated with
    installing 1/2 duplex antenna in another location at hatchery.  Noise
    tests did not show problems for full duplex antenna system when 1/2 duplex
    was turned on, however full duplex system interfered with 1/2 duplex antenna
    read range.  Tribes will further investigate feasibility of installing 1/2
    duplex antenna with agreement that full duplex system will not be compro-
    mised.

    02/19/10 - Antenna 2 has had high noise for several weeks, test tag and
    several fish still detected so antenna still functioning.  Kurt Steinke
    (AFTC) ran diagnostics, possible corroded capacitor connections.  Starting
    on 2/20, timer tag no longer being recorded, also noise levels were very
    high and constant.  Will investigate problems.
