USGS Water Data for Dist. of Columbia
During cold
weather, ice effects on stage, ground water levels, precipitation and
water quality parameters at some stream-gaging stations and wells are
likely. Data values reported on these pages may be significantly higher
or lower than actual values. Adjustment of data for ice effects can
only be done after detailed analysis. Users are encouraged to contact
this office for more information on specific stream-gaging stations or
wells.
