MonitoringLocationDescriptionText This site is a 5:1 broadcrested v-notch weir at the outlet of a 31 sq kilometer (12 square mile, 7576 acre, 3066 ha) subwatershed nested within Goodwater Creek Watershed, sited immediately north of Centralia, MO. Area-weighted daily rainfall is available for this watershed, with this same siteid. MOGC0297 is a weir located 8.5 km (5.3 mi) NNW of the intersection of MO highways 22 and 124 in Centralia, MO. The general legal description is the NE 1/4 of Section 15, T52N, R11W in Audrain County, MO. Commonly referred to as Weir 9. Flows are estimated from 5 to 15 minute stage measurements, converted to flow rates through a rating curve, and aggregated at a daily time step. The rating curves for the research weirs on Goodwater Creek were originally developed using discharge measurements performed between 1971 and 1986. Discharge measurements performed from 2006 to 2001 at another downstream weir indicated that discharge values at high stage were on average 30% below the values indicated by the existing rating curve. A retrospective analysis of the rating curves for Weir 1, downstream from Weir 9, followed, which is described in details for Weir 1 in Baffaut et al. (2014) and resulted in new rating curves for Weir 1 and 9 in 2012. These rating curves are valid for the entire period and were applied to the whole data set. A copy of the revised rating table for Weir 9 can be found via the following link: http://www.ars.usda.gov/sp2UserFiles/Place/50701000/MOGC_StreamWeir_9_RatingTable.pdf Discharge values obtained from previous rating curves are available upon request by contacting Dr. Baffaut.
