This section of the website contains a variety of resources to learn more about Marys River watershed and other area rivers. It contains a short overview of the natural history of the watershed, a folio of maps, links to publications, videos and data from Marys River Watershed Council field assessments. It also includes an archive of past MRWC newsletters.

One of the most fascinating aspects of rivers is how much they change — in terms of flow, form, and wildlife. If you are looking for current stream flow, historical data or future projections, check out the following sites:

Northwest River Forecast Center (NWRFC) provides an overview of hydrologic conditions for the entire area at a glance. Click on any station for more details. The station PHI03 (the next link on this page) is the Marys River at Bellfountain Road, and the station COR03 is the Willamette River at Corvallis.

The NWRFC Marys River Station provides current and predicted stage (water level) and discharge (the volume of flow per second) for an approximately 10-day moving window, along with historical high and low flow data for that date. This site also provides local weather forecasts and links to related information.

The USGS Bellfountain Gauging Station provides 6-day graphs of stage and discharge, updated about every four hours in summer and hourly in winter. There is about an hour lag time from gauge recordings to website. Data at this site provide maximum, minimum, 25%, 50% and 75% percentile discharge for the day, based on almost 60 years of data.
