Methods:	Stage height measurements were taken with a Stevens chart recorder and also with a measuring stick placed on the upstream side of the two culverts. Readings on the measuring stick are in centimeters from the bottom of the river to the water surface. Discharge calibration measurements were taken at 60% of depth at 20-30 points along a cross sectional transect of the river, 10 meters downstream of the culverts. Measurements were made using both Marsh-McBirney and Teledyne-Gurley flow meters. Raw data from the calibration measurements are available. Notes: Once again we have had to calculate a new rating curve to determine discharge for the season. The standpipe from '91 was washed out in the early June high water, one of the culverts was badly damaged and the stream morphology was altered by erosion and sediments from the road wash out. A new standpipe was installed in late June but was washed out on the 1st of July. A second standpipe was installed on the 4th of July. Normally we would use the datalogger to supply missing stage height data but this was not possible this year. The pressure transducer was washed downstream to some unknown location in the early June flood. The datalogger itself disappeared in the August 26 flood, with a good deal of data on it that had not yet been collected. Discharge was calculated for six stage height readings a day, taken at four hour intervals. On several days there is missing stage height data which means that average stage height for these days is not accurately represented. These days are as follows: June 27 Only 1 reading - 1600 AST , June 28 No readings June 29 No reading at 0000 and 0400 July 1 No reading at 2000 July 2 Only 1 reading - 1000 July 3 Only 2 readings - 0930 and 1200 July 4 No reading at 0000 and 0400 Aug 14 No reading at 1600 and 2000 Aug 15 Only 2 readings - 1600 and 2000 Breck Bowden did some surveying at the Kuparuk road crossing this year to help us establish permanent reference marks. Hopefully this will help to give us better year to year continuity. Sampling Description. None
