Notice:Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake, Volcano, LANDSAT and Water information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown.

Model Form:

At this site, real-time estimates of water quality depend on the availability of instantaneous discharge and specific conductivity measurements. During winter months, real-time water quality estimates may not be available for this site due to effects of ice.
