Map of USGS gauge 01104415 and the river around it
Where CAMBRIDGE RES., UNNAMED TRIB 2, NR LEXINGTON, MA sits.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. MassWildlife publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Massachusetts rule: 68°F.
Species list not on file for this gauge. Check the Massachusetts Division of Marine Fisheries / MassWildlife: Massachusetts trout stocking report · Massachusetts recreational saltwater fishing regulations.
Normal for Nov 5: 0.06–0.49 ft³/s (middle half of 24 years of record). Now: 0.04 ft³/s, below normal.
Below normal for this date. 0.04 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 24 years of record (1998–2026): 10th 0.04, 25th 0.06, median 0.17, 75th 0.49, 90th 1.1 ft³/s.
Daily means on record for Nov 5: lowest 0.02 ft³/s, highest 1.37 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Falling over 24 hours: discharge down 20%, from 0.05 to 0.04 ft³/s. Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
Turn Around Don't Drown (National Weather Service)Specific conductance 2,160 µS/cm at Nov 4, 8:40 AM EST; 7-day range 2,110–2,170 µS/cm; more than a day old
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) and Water (U.S. Geological Survey)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 9:33 PM EST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
