Is there water?
Whether there is a river here on your dates, and what kind of water it is.
Glacier-fed / snowmelt, distinctive glacial-blue color; monsoon Jun-Aug sharply raises levels. Confirm.
Jan-Jun and mid-Sep-Dec; monsoon Jun-Aug generally too high. Confirm.
Spring and Fall - roughly Mar-May and Sep-Dec. Confirm.
Cold glacier/snowmelt fed; wetsuit/splash gear sensible outside warmest months
Monsoon Jun-Sep high fast water and flood risk; valley carries general GLOF hazard
Grade & who can come
A river changes grade with its level. These grades describe a normal flow - in flood the same run is harder, and often a different run entirely. Check the gauge before you commit.

Wood/strainers recurring (Strainer Paradise); sticky hole at Pipeline; split channels at Wrathful Buddha; scout upper Class IV
