Map of USGS gauge 04114000 and the river around it
Where GRAND RIVER AT PORTLAND, MI sits, with 3 other gauges on the same river and our water's map point.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Michigan DNR publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Michigan rule: 68°F.
Normal for Nov 5: 325–1,030 ft³/s (middle half of 68 years of record). Now: 287 ft³/s, below normal.
Below normal for this date. 287 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 68 years of record (1953–2026): 10th 239, 25th 325, median 577, 75th 1,030, 90th 1,680 ft³/s.
Daily means on record for Nov 5: lowest 133 ft³/s, highest 2,460 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).
Steady over 24 hours (−5.3% discharge). 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.
