Season
Colorado River District waters follow Colorado River / district-specific freshwater rules in the 2026 Freshwater Sport Fishing Guide (not the coastal district tables alone). Look up Colorado River, border waters, and named Imperial / Riverside / San Bernardino waters in the guide’s special and district sections. IMPORTANT: If your lake, river, or stream is named in the Alphabetical List of Waters with Special Fishing Regulations (2026 Freshwater Sport Fishing Guide), those special rules override this district default.
