when is a good time to go watch the kokanee run up the henry's fork and moose creek?

is it a certain time of the year or more based on water temp?

Answer: 

These systems have early-run kokanee.  They begin their spawning migration in mid-August and usually peak in early Septemeber.
Late running kokanee are found in north Idaho in the big lakes.  Up there, kokanee will spawn in November and December.
