     Historical Data


        No historical is available for this stream.


  =============================================================================

     Reference Point

        Unt to Burdens Cr. model's stream cross sections are referenced in
        feet above the confluence with Burdens Creek.


  =============================================================================

     Invert Data Support Information

        The cross section inverts were calculated by subtracting
        the maximum rod reading (from field survey data) from the
        corresponding Height of Instrument.

  =============================================================================

     Starting Station, Starting WSEL, and Starting Slope

        Unt to Burdens Cr. has been previously studied.  The starting station
        for Unt to Burdens Cr. is at  confluence with Burdens Creek.

        Starting WSEL is an estimated value based on the furthest D/S
        invert.

        Starting slope is estimated using WSEL's at the furthest D/S
        section of the study.
