The Poudre is good to go for rafting starting at .7 for Bridges - not that it is a lot of fun but you can get a 13' raft with custies down at that level.
Check Poudre Rock Report
for current flows.
Last report was 1.3, but as it is warming up and the sun is shining, look for the levels to come up for the weekend. Over 1.7 a puma should be able to run from Upper Mish down through Bridges, but it might be a bit scrapy in Poudre Park, over 2 would be better and things start to gel above 3 ft. That is also about the minimum (3 ft.) level to make Upper and Lower Rustic worthwhile.
