The river is floatable and fishable most of the time during the winter. Having said that, the current flows are around 550 cfs which makes it kind of boney in places. The water has also been kind of off color due to the inflow from the North Fork of the Gunnison with quite a bit of ice moving down as well. If you decide to go, I suggest putting in at the Pleasure Park and taking out at the BLM's Orchard site takeout. There are 2 put-ins at the Pleasure Park. One is private and the other is BLM. The Orchard takeout is BLM and open to the public. The next public takeout below the Orchard is at the Highway 65 bridge which will add at least 2 hours to your float and it is relatively unproductive water as far as fishing goes this time of year. If you want my 2 cents worth, I would wait until conditions improve in the spring.
