    Retrieval of the prototype pit-tag detection site (PD7) occurred on two
    separate dates in late 2011.  On 28 September the alternative
    configuration (coils 5 and 6) was removed due to lack of detections.
    The remaining coils (1,2,3 and 4) were retrieved on 25 October as
    upcoming tidal cycles would not be conducive for removal until 2012.  A
    total of twenty-one pit-tagged fish were detected from early August to
    late October and included adult Chinook and coho salmon,steelhead, as
    well as, sturgeon and northern pikeminnow.

    Activation of the prototype pile dike PIT-tag detection site (PD7)
    occurred on 10 August, 2011 at river kilometer 70 in the Columbia River
    Estuary.  The site consists of four PIT-tag coils (ea.1.2 m wide × 3.0 m
    deep) fixed to the downstream side of a pile bundle located at the
    offshore terminus of the pile dike structure, forming a 4-coil (coils
    A1, A2, A3, A4) antenna array (3.6 m wide × 6.4 m deep).  On 14
    September two additional detection coils were added (A5 and A6)
    approximately 30 feet nearer to the shoreline on an adjacent piling to
    test an alternative configuration.   These two coils comprised a 3.0 m
    wide x 2.6 m deep antenna array and were deployed 1.8m below the surface
    of the water.
