Before <br />the flood, the section at the upstream station on Trout Creek had been a <br />nearly ideal stage measuring section because of its straight alignment, <br />even grade and well armoured bottom. After the flooding, this section was <br />nearly unrecognizable because of changes in the channel alignment and <br />streambed material. The downstream station on Trout Creek was in a section <br />that was changing and was threatened by bank caving but was expected to <br />last several more years, especially since the measuring section was still <br />providing reliable streamflow records. The flood accelerated bank erosion <br />to the extent that the present bank is several feet behind where the <br />station was located. Immediately downstream the abandoned TR-4 alluvial <br />well was originally about 10 feet from the bank, and is now in the middle <br />of the channel, again due to the flooding. <br />During the year, the channels were changing enough that any of the <br />locations that looked good as guage sites couldn't be expected to be stable <br />long enough to justify building a permanent installation, at least in 19.94. <br />4f ter the peak flow in 1985, we will have e much better idea which <br />locations will likely be good long term gauge locations and be able to, <br />hopefully, reestablish TR-a. <br />The five alluvial wells were not damaged by the flood and operated <br />normally. (The old TR-4 well was damaged as noted above.) The spoil well <br />on West Ridge was installed late in the ,year soon after the area was <br />regraded. The well appears to be in good condition and samples were <br />collected. <br />
