Well so everyone knows (which I did not) and because I got so much feed back on here from guys who have fished the fork and probley knew. I made some calls today and found out that THERE IS NO RIDING OF ATVs OR SNOW SLEDS ON WILLIAMS FORK. I was told it is a safty issue due to the large draw of water at times. I would think that is this is such a concern to Denver H2O that they would just close it in the winter ala Spinny. Anyway Thanks all, Have a great weekend and hope everyone gets out.
