Gauge Description:

Flows in this reach will be just slightly higher than shown at the Happy Isles gauge, as Tenaya Creek comes in below the gauge.. The park service does not allow boating on this section when the river level is too high under the Sentinal bridge.   "Rafting is not permitted whenever the river stage (depth) reads 6.5 feet or higher."  Floating is also limited to the hours between 10 AM and 6 PM.   Yosemite Water Activities

At this time it is not known what level on the Happy Isles gauge corresponds with the level that is closed to boating.  Air tempurature readings can be found on the weather tab.   We are searching for an online source for water tempurature readings.
