As of July 31, 2011, water-quality data collection at this streamgage has been discontinued due to funding reductions from partner agencies. Although historic data will remain accessible, no new data will be collected unless one or more new funding partners are found. Users who can contribute funding for the non-Federal share of costs to continue operation of this water-quality streamgage should contact Brenda Majedi of the USGS Maryland, Delaware, DC, Water Science Center at 443-498-5527 or email email@example.com.
The data used to produce these plots are provisional and have not been reviewed or edited. They may be subject to change.
Duration Curve For Period of Record
Duration curves (or cumulative frequency curves) are constructed by ranking all values for a given period from largest to smallest, and assigning a percentage exceedance to all values relative to the largest value.
