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 blfeit@usgs.gov.
