I know not all bass spawn at the same time but does anyone know when bass spawn on average in Colorado? I fish mainly medium size ponds in northern Colorado and can tell they are around beds but can't figure out if the are pre spawn, post spawn or spawning. I have not seen any eggs or fry but it seems like their leaving the beds I have seen. Anyone know from their own experience?

When I lived in Denver, metro area ponds had LMB spawning in April.  Wish I had more insight for the FOCO region but some of the fellas from FE should help. I would place money that they are in the post spawn where you are at. Throw a 3" white grub for me!Tight lines. 

Told ya

Thanks. From what I can tell you are right. We are solidly post-spawn now. 

have you tried gateway pond, next to walmart ? if not i will try it and let you know

The Spawn in Colorado is usually mid April to Mid May
