Sometimes, especially early in the season, you may be the first person out there. Be prepared to be a pioneer! You may have to turn around if it gets too bad. And do notify the land manager! Even if there's no trail maintenance budget (which there probably isn't), the land managers may be able to send volunteer groups that way. Also, if there's a hiking forum for that area, post a report there. If the trail is free and clear, a lot of folks will be happy to know!
