About this location

Hobbs Bk Below Cambridge Res Near Kendall Green

The stream gauge measures water flow, which is provided by precipitation and runoff from surrounding urban areas. Tributaries that can impact flow include the Beaver Brook and Stony Brook, while the Stony Brook Dam can affect downstream water levels. Seasonal trends show that flow is highest during the spring and early summer due to snowmelt and rainfall. However, flow can be significantly reduced in the summer months due to increased water usage and drought conditions. One interesting fact about the hydrology of this area is that the Cambridge Reservoir was originally created to provide a drinking water supply for the city of Boston.

Regional streamflow

Nearby streamflow levels

Cross-check Hobbs Bk Below Cambridge Res Near Kendall Green's discharge against nearby gauges to spot whether the change here is local or regional.

Regional snowpack

Nearby snowpack data

Snowpack at SNOTEL stations near Hobbs Bk Below Cambridge Res Near Kendall Green. Spring snowmelt is the dominant driver of streamflow in mountain basins -- a deep snowpack upstream means more runoff later in the season.

River levels & flood safety

Read the level before you go
A river that's runnable at one flow can be deadly at another. Check current discharge and gage height — like the values shown above — against the flood-stage thresholds, and remember levels can spike fast after rain or a dam release.
Respect cold water
Snowmelt rivers run cold even in summer. Sudden immersion triggers cold-water shock and saps strength within minutes. Wear a PFD, dress for the water temperature (not the air), and never wade or paddle alone.
Watch for swiftwater hazards
Strainers (downed trees), undercut rocks, and low-head dams are the deadliest features on moving water. High, fast, muddy water hides them. If in doubt, scout from shore and portage.
Mind flash floods & releases
Narrow canyons can flood from a storm miles upstream, and dam-controlled reaches can rise without warning. Know the forecast, the release schedule, and your exit before you launch.

Track Hobbs Bk Below Cambridge Res Near Kendall Green in the Snoflo app

Save this gauge as a favorite, set push alerts when streamflow crosses a threshold (e.g. "alert me when Hobbs Bk Below Cambridge Res Near Kendall Green crosses 5,000 cfs"), and Snoflo's iOS app will push the moment USGS reports the crossing.

FAQ

About Hobbs Bk Below Cambridge Res Near Kendall Green

Where does the streamflow data for Hobbs Bk Below Cambridge Res Near Kendall Green come from?

Discharge, gage height, and water temperature come directly from the USGS streamflow gauge 01104430. Snoflo refreshes the time series throughout the day. Forecasts come from the NOAA / yr.no feed Snoflo's iOS app uses.

How often is the report updated?

USGS gauges report continuously (typically every 15 minutes). Snoflo pulls fresh values throughout the day — look for the "as of" timestamp on the streamflow hero card.

What's the difference between discharge and gage height?

Discharge (cubic feet per second, or cfs) is the volume of water flowing past the gauge each second. Gage height is how high the water sits at the gauge (feet). They're related by a rating curve specific to each gauge — higher water means more flow, but the exact ratio depends on channel shape.

How is "percent of median" calculated?

Today's discharge is compared to the historical median discharge on this calendar day across the gauge's full record. 100% = right on median; 200% = a very high year; 30% = a drought-level low.

What are flood stages, and is this river safe right now?

Flood stages are NWS-defined gage-height thresholds — Action, Minor, Moderate, Major — marking when nearby roads or floodplains start to be affected. "Safe" depends on your activity and skill: a level that's a fun paddle for an expert can be lethal for a wader. Always check the current level against the thresholds above and the safety links, and when in doubt, stay off the water.

Can I get alerts when Hobbs Bk Below Cambridge Res Near Kendall Green rises?

Yes — flow alerts are managed in the Snoflo iOS app. Favorite this gauge, set a streamflow threshold (e.g. "alert me when discharge crosses 5,000 cfs"), and you'll get a push the moment USGS reports the crossing.
