No Public Fishing Access at Riverside Resevoir - It is Privately Owned.
Unfortunately, Riverside Reservoir near Masters Colorado off of Hwy 34 is privately owned by the Riverside Ditch and Land Company. It is also surrounded by Eagles Nest Ranch which is owned by Phil Anschutz. There is no public access for fishing, hunting, boating, etc., Many forums note that your can fish this place but the company employees will asked you to leave if found on their property or a trespass violation will be issued. Also, some forums and websites confuse this reservoir with riverside park near Evans, CO which has a pond for fishing or Riverside Campground in central Colorado.
