The year on this river
In a typical year at the Markleeville gauge, the East Fork Carson River runs fullest Apr–Jun and leanest Sep–Nov. 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 May days at this gauge ran above 1,070 CFS; the October median is 74 CFS.

When is the East Fork Carson River usually at its fullest?

Is the East Fork Carson 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 105 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.
