The nearby Harriman State Park offers miles of trails for hiking and horseback riding, and the park is home to a variety of wildlife, including elk, moose, and bison.

When it comes to fishing, the best time to visit Henry's Lake is from late May through early September, when the water temperature is in the mid-60s to low 70s, and the fish are actively feeding.

Angling Safety Guidelines

Know the Regulations
Check local fishing rules, seasons, size limits, and license requirements to ensure legal and sustainable angling.
Handle Fish Responsibly
Use wet hands, minimize air exposure, and release fish gently to improve survival rates when practicing catch-and-release.
Choose the Right Gear
Match your rod, line, and tackle to the species and conditions to increase success and reduce unnecessary harm to fish.
Respect the Waterway
Avoid disturbing habitat, prevent bank erosion, and keep a safe distance from spawning areas to protect ecosystems.
Keep It Clean
Pack out all line, hooks, bait containers, and trash—discarded gear can injure wildlife and degrade waterways.
