What Makes Green Mountain Reservoir Different

Green Mountain Reservoir is a deep, narrow Blue River lake with steep mountain sides and a long old river channel. Water transfers and storage changes can move the useful shoreline far up or down the banks.

Lake trout favor deep points, channel bends, and humps that can be fished with a jig. Brown trout and cutbows may come shallower near moving water. Salmon are open-water fish, so find the school before choosing a trolling depth.

A falling lake can leave a familiar bank far above the water. When that happens, ignore the old shoreline and follow the shape of the point until it meets the old Blue River channel. That lower edge is more useful than casting the newly exposed bank.

Green Mountain Reservoir FAQs

Why do water levels matter at Green Mountain Reservoir?

A large drawdown can leave old shoreline cover dry and move the best fishing toward the old Blue River path.

Where should anglers jig for lake trout at Green Mountain Reservoir?

Try a deep point, channel bend, or hump where fish show close to the bottom.

What is a useful salmon plan at Green Mountain Reservoir?

Search open water for a school, then troll a spoon through that level rather than dragging near the bottom.
