Is it legal to cacth spawning Kokanee in Mores Creek?, Can they be snagged?,and if so what is the limit?

Answer:

You can catch 6 kokanee from Mores Creek, as per the bag limit for kokanee listed on page 15 of the Fisheries Rule booklet.  It is illegal to snag kokanee or any other game fish, so the answer to the second half of your question is "no."
