Yes, spearguns are legal in Colorado for recreational and commercial use, but compliance with state wildlife regulations and local ordinances is mandatory. The Colorado Parks and Wildlife (CPW) enforces restrictions on speargun specifications, fishing seasons, and prohibited species to align with conservation goals. Violations may result in fines or permit revocation under the 2024 Wildlife Regulations Update.
Key Regulations for Spearguns in Colorado
- Prohibited Species & Methods: Spearguns may not be used to harvest game fish or species listed under CPW’s Prohibited Species List (e.g., trout in certain waters). Spearfishing is restricted to non-game species unless otherwise permitted by specific regulations.
- Seasonal and Area Restrictions: Spearfishing seasons vary by waterbody; for example, the Arkansas River’s spearfishing season for carp closes March 1–June 30. Always verify local CPW postings for temporary closures or gear restrictions.
- Speargun Specifications: Only manually powered spearguns (no pneumatic or spring-loaded mechanisms) are permitted. Barbed spears exceeding 3/4-inch diameter or 18 inches in length are banned to prevent overharvesting.
Local jurisdictions, such as Boulder County, may impose additional ordinances (e.g., requiring permits for spearfishing in municipal reservoirs). Consult the 2026 CPW Fishing Regulations for updates on speargun use in state parks or federally managed waters. Non-compliance risks penalties under Colorado Revised Statutes § 33-6-109.
