Also- This Colorado State Wildlife Area FAQs pdf provides some additional info. It includes this paragraph...
"Here are the current 2020 prices of resident licenses that are most cost-effective: Adult fishing, $35.17; small game, $30.11; combo small-game and fishing, $50.37. Senior fishing is $9.85. A person 18 years of age and older and under 65 years of age will also need a Habitat Stamp when applying for or purchasing a hunting or fishing license. No Habitat Stamp is required for applying for or purchasing a person’s first two one-day hunting or fishing licenses. The 2020 charge for a Habitat stamp is $10.13. That is a one-time charge in a 12-month period, so that is not charged on the purchase of another license(s)."
I then went to this Colorado Parks and Wildlife site for more info on fishing licenses and non-resident costs.
The $35.17 adult-annual fishing license is $97.97 for non-residents.
In addition to the adult-annual cost, those age 18-64 must also pay an additional $10.13 for a Habitat Stamp (for the first license purchase of the year).
The $9.85 Senior annual fishing license is not available to non-residents. There's no such thing as a Senior Non-Resident annual fishing license.
There are one-day and five-day licenses available to non-residents. The one-day is $16.94 and five-day is $32.14. (Note- no Habitat Stamp is required on the first two purchases of a one-day license in any one year. Presumably, those 18-64 would have to pay the $10.13 for a Habitat Stamp on top of the cost for the five-day license.)
Please note that these are costs for each individual in your party over the age of 18. (And if anyone under 18 plans to fish or hunt, they need a license)
The fine for being caught without a fishing or hunting license is $140 and five license suspension points (per person).
