What is the amount of drop and water flow on the Beech Fork?
The channel experiences extreme hydrologic regimes, often dropping below 1 cfs for the months of September, October and November, and then peaking over 5,700 cfs in February, March and April. USGS Gage 3301000 is set on the downstream low chord of the US 31E Bridge. Gage 3301000 has recorded most mean daily values since November 14, 1940 with a gap in the record from water year 1975 to 1997 and water year 2000. Daily flow data from the period of record was reduced. Figure 1 below presents the daily flow that occurs 50% of the time.Design flow for municipal intake is all flows above 1cfs. Design flows for recreation enhancements range between 350cfs-3500+cfs; which occurs during the period of late December to mid May. The construction period should coincide with low flow periods of August-October.At 1cfs flow, the hydraulic drop over the structure is 6 feet. At flows above 5,700 cfs the structure is totally submerged with no hydraulic drop other than the gradient of the river. The struc
