The Ohio Water Science Center has transitioned to a new data management software package. While you may not have noticed this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible. See the Dec 8 news entry for more information at: https://help.waterdata.usgs.gov/news

 03262700 Great Miami River at Troy, OH
 LOCATION.-- Lat 40°02'25", long 84°11'52", Miami County, OH, Hydrologic 
     Unit 05080001, 400 ft downstream from B & O Railroad bridge, 1,300 ft downstream 
     from bridge on State Highway 55 at Troy, 1.2 mi upstream from small left bank 
     tributary, 2.3 mi downstream from Spring Creek, and at mile 105.
 DRAINAGE AREA.-- 926 mi2.
 PERIOD OF RECORD.-- Water years 1961, 1962 (occasional low-flow measurements, published 
     as Miami River at Troy). October 1962 to current year.
 REMARKS.-- Flood flow regulated by Lockington retarding basin on Loramie Creek 15.5 mi 
     upstream. Low and medium flow slightly regulated by Indian Lake, 53.5 mi upstream 
     from station, and by Lake Loramie 36.6 mi upstream from station on Loramie Creek; 
     combined capacity, 58,900 acre-ft. Recharge to the City of Troy wellfield is largely 
     induced infiltration from the Great Miami River. Groundwater pumpage upstream from 
     the station is returned to the river as treated wastewater 1 mi downstream from the 
     station and could affect low flow.
 EXTREMES OUTSIDE PERIOD OF RECORD.-- Flood of June 11, 1958, reached a stage of 16.4 ft; 
     discharge, 21,000 ft3/s.
