Station information
About station
This station is located on the Potomac river under Chain Bridge Road, used by Occoquan Lab for stream water quality monitoring at Potomac River for MWCOG. Due to a constriction in the Potomac River channel near Chain Bridge the water is well-mixed and suitable for representative point sampling. The site, however, is not ideally suited for stream gaging due to the variable backwater effects from the tidal fresh water portion of the estuary and the topology of the stream bed near Chain Bridge which complicates development of low and moderate flow rating table.
