Methods:	Stage height measurements, taken at the water line, were read from a measuring stick placed vertically on the upstream side between the two culverts. The readings were in centimeters up from the bottom of the river. Notes: The calibration of the discharge regression equation was rechecked during the summer at three different stage heights (88cm, 89.5cm and 112cm). Actual flow measurements were taken at 10cm depth increments every 1 meter along a cross sectional transect of the river, just downstream of the culverts at the gas pipeline crossing. Calibration measurements were taken using a Marsh-McBirney, Model 201 portable water current meter. Raw data from the calibration measurement are available. Because of excessive 1989 spring break-up, the original stilling well and stage height measuring stick were washed out and lost. A replacement measuring stick was located in the same position as the original, although the zero point for the original stick was not recorded, so it is unknown how the two sticks correspond with respect to their zero points. It was estimated they were within 6cm of each other. In addition the section of the north culvert that was previously bent (causing the decrease in the slope of the 1986-1988 regression curve for stage heights <105cm) was further bent during break-up. The three 1989 calibration values corresponded fairly well to the previous year's regression curve when there is no change in the slope of the curve at stage<105cm. There was not enough calibration data collected to create a new discharge regression curve for 1989. Therefore, 1989 discharge at all stage heights was calculated using the 1988 curve at a single slope (.016) . Sampling Description. None
