The year on this river
In a typical year at the Indian Lake gauge, the Hudson River runs fullest Mar–May and leanest Jul–Sep. Where today's reading falls inside that rhythm matters more than the raw number — the same flow that feels thin in spring can be the summer norm. Half of all past April days at this gauge ran above 3,550 CFS; the September median is 683 CFS.

Common questions
When is the Hudson River usually at its fullest?
At the Indian Lake gauge, the fullest stretch of a typical year is Mar–May, with the single highest monthly median in April (about 3,550 CFS). The leanest months are usually Jul–Sep.
What is a typical summer flow on the Hudson River?
The July median at this gauge is about 689 CFS — half of past Julys ran higher, half lower. Late summer is this river's lean season, so expect readings to drift down as the season goes on.
Is the Hudson River safe to float right now?
No flow number can answer that, and this site never labels a river safe. What the data can tell you is how today's reading compares with 118 years of this date's history — well above typical means pushier, colder, faster water. Pair that context with a PFD, a look at the river from the bank, and a call to a local outfitter before you commit.
