Stream Access and Trespass in Wyoming

In Wyoming, understanding stream access and trespass laws is crucial for outdoor enthusiasts. Here's what you need to know:

  • Trespass Law: Public entry onto private land is only allowed with explicit permission from the landowner.

  • Floating Through Private Land: Floating through private land is legal, but you must remain in your boat at all times unless you have obtained permission from the landowner.

  • Portages Around Obstacles: Short portages around non-navigable obstacles are permitted by state law. However, remember that the streambed itself belongs to the landowner, so wading or anchoring without permission is considered trespassing.

  • Access to Public Lands: Access to public lands is permitted if accessed by floating on navigable water or from existing public roads. Always check with the relevant land management agency if you're unsure.

  • Useful Resources: Public land maps from the Bureau of Land Management can help you avoid trespass violations.

  • Respect for the Environment: Always respect the land and landowners by removing litter and minimizing your impact. Treat access as a privilege to ensure continued access for fishing and hunting activities.

Mercury Advisory for Fish Consumption in Wyoming

Fish offer numerous health benefits but can also pose risks due to mercury contamination. Here's what you need to know to make informed choices:

  • Health Benefits of Fish: Fish are high in protein, nutrients, and omega-3 fatty acids essential for heart and brain health.

  • Mercury Risks: Some fish contain high levels of mercury, particularly harmful to children and pregnant or nursing women. Mercury can impact fetal development and children's brain growth.

  • Guidelines for Safe Consumption: To minimize mercury exposure, follow these guidelines:

    • Pregnant or nursing women, children under 15, and those planning to become pregnant should eat no more than 2 meals per week (8 ounces per meal) of low-mercury fish.
    • Low-mercury options include rainbow trout, cutthroat trout, kokanee from Wyoming waters, as well as shrimp, canned light tuna, salmon, Pollock, and catfish from stores and restaurants.
    • Consumption should include fish from all sources, including those caught in Wyoming and purchased commercially.
  • Choosing Fish Wisely: Mercury levels tend to be lower in smaller and younger fish. Therefore, prioritize smaller fish for consumption.

  • Species with Lower Mercury Levels: Rainbow trout, cutthroat trout, and kokanee salmon generally contain less mercury than species that prey on other fish, such as walleye, brown trout, lake trout, catfish, and burbot.

  • Specific Waters: Some Wyoming waters may have higher mercury levels in certain species. Tighter consumption guidelines are provided for these species in affected waters. Visit the Fish Consumption Advisory website for detailed guidelines and updates.

Ensuring awareness of mercury levels in fish and following consumption guidelines helps safeguard health while enjoying the benefits of fish consumption in Wyoming. For more information and updates, visit
