Trout Species

What's swimming in Boulder Creek

No CPW fishery survey specific to this stretch was found. The species notes below come from angling reference sites and a fly shop; regulations come from official City of Boulder and CPW sources.

  • RiverReports, Orvis and Rocky Mountain Anglers all describe a mixed trout fishery through the in-town and canyon-mouth reaches: Brown Trout as the most common catch, wild Rainbow Trout, occasional Brook Trout, and rarer Cutthroat/Cuttbow (Orvis; Rocky Mountain Anglers).
  • From the upper end of Eben G. Fine Park downstream to 55th Street, City of Boulder regulations restrict fishing to artificial flies and lures only, and every trout caught must be returned to the water immediately (City of Boulder OSMP; CPW fishing regulations).
  • Boulder Creek downstream of Valmont Road -- the stretch nearest the North 75th Street gauge this page tracks for live flow -- is closed to fishing year-round to slow the spread of New Zealand mudsnails; the special-regulation, artificial-flies-only water above 55th Street is unaffected by this closure (City of Boulder, New Zealand Mudsnails).
  • Boulder Creek is not Gold Medal water (CPW fishing regulations).
Access & Regulations

Getting to Boulder Creek

The tracked gauge sits downstream of the creek's only special-regulation reach, at the lower end of that reach rather than inside it.

Public Access
  • Eben G. Fine Park, City of Boulder -- creek frontage and a pedestrian bridge over Boulder Creek connecting to nearby trails; year-round restrooms with limited fall/winter hours, groups capped at 50, no glass containers or alcohol (City of Boulder). This park also marks the upper boundary of the creek's special-regulation reach (CPW special regulations).
  • Rogers Park, Boulder County Parks & Open Space -- stream fishing for rainbow trout, 4-fish limit, artificial and live bait both permitted; open sunrise to sunset, no overnight parking (Boulder County).
  • Anglers 16+ need a Colorado fishing license; a standard license covers one line, a second requires a $5 second-rod stamp (City of Boulder OSMP).
Regulations
  • Upper end of Eben Fine Park downstream to 55th Street: artificial flies and lures only, trout returned to the water immediately (CPW special regulations). Outside that reach, statewide limits apply: 4 trout daily, 8 in possession (CPW statewide limits).
