| # | Point | Type | Lat, Lon | Notes |
|---|---|---|---|---|
| 1 | Henrys Lake Dam Outlet dam · National Inventory of Dams ID00008 | Dam / hazard | 44.59725, -111.35341 | The lake's only outlet structure, at the southeast corner. Below it the water is Henrys Lake Outlet and then the Henrys Fork, each with its own Idaho season - not part of this sheet. |
| 2 | USGS 13039000 — Henrys Lake near Lake, Idaho USGS · lake level and storage | USGS gauge | 44.59722, -111.35361 | Lake-stage gauge on the shoreline at the outlet, 25 m from the dam. Matched on ref to the OSM monitoring station 4 m away; the station 0.42 km downstream is 13039500 on the Henrys Fork, not this one. |
| 3 | Henrys Lake — South Shore BLM · ramp and dispersed camping | Access / boat ramp | 44.61558, -111.41715 | IDFG access site on BLM ground; no ramp is tagged here in OSM. IDFG warns the access roads turn very slick when wet or snow-covered, and caps camping at 10 days in any 30. |
| 4 | William Frome County Park Fremont County · ramp, dock, camping | Access / boat ramp | 44.65028, -111.43705 | Northwest shore. IDFG and IDPR publish this site 19 m apart and an unnamed OSM slipway sits 35 m away, so three sources agree on it. |
| 5 | Staley Springs closed water Idaho closed-water boundary | Regulation section limit | 44.65998, -111.43407 | Idaho closes the portion of Henrys Lake inside the posted Staley Springs boundaries. Those boundaries are posted on the water and are not published as coordinates, so this marker sits on the IDPR-inventoried Staley Springs site. |
| 6 | Jared's Wild Rose Ranch Resort Two concrete ramps · fee, open to non-guests | Access / boat ramp | 44.66807, -111.40148 | North shore. The resort states both ramps and their protected marinas are open to everyone, not only guests, for a launch-and-park fee, and its mini-store carries flies, lures and live bait. OSM maps two slipways and four piers here. |
| 7 | Lakeshore Lodge IDPR ramp inventory · access unconfirmed | Access / boat ramp | 44.66240, -111.38354 | Listed for Henrys Lake in Idaho Parks & Recreation's boat-ramp survey, 51 m off the shoreline. OSM carries no ramp here and no website for the business could be reached this run, so treat public access as unconfirmed. |
| 8 | Henrys Lake State Park Campground IDPR · 83 serviced sites, 3 cabins | Campsite | 44.61930, -111.37021 | Adam's and Caddis loops, $7 vehicle entry fee. The park stays open and staffed in winter with about a dozen dry RV sites and three heated cabins, and no water. The dump station is closed for the 2025/26 season. |
| 9 | Henrys Lake State Park boat ramp IDPR · paved two-lane ramp, launch dock | Access / boat ramp | 44.62019, -111.37322 | Southeast shore, ADA ramp. An unnamed OSM slipway sits 9 m away. Coordinate is IDPR's boat-ramp survey; the park page's own coordinate is the entrance kiosk, 456 m inland. |

About the Henrys Lake
Henrys Lake sits at about 6,470 feet in a basin below Targhee Pass in eastern Idaho, minutes from the Montana line and the west side of Yellowstone. It covers roughly six and a half thousand acres and drains about ninety-four square miles, and the gauge near the lake reads stage. What makes it extraordinary is not size but fertility: the lake is shallow, weedy and extremely rich, and it grows trout to weights that a water of this elevation has no business producing.
Depth is the governing fact, in the opposite direction from most famous trout lakes. Henrys averages roughly twelve feet and rarely exceeds twenty, so sunlight reaches most of the bottom and the weed growth is prolific. That vegetation supports enormous populations of damselflies, leeches, scuds and midges, and the trout feed on invertebrates rather than on baitfish for most of the year. Springs enter around the shoreline and the inlet creeks matter disproportionately, because in a shallow lake that can warm sharply in midsummer the cold water is where fish concentrate. Wind is a constant and a genuine safety consideration in a small boat.
Yellowstone cutthroat trout are the signature fish and run large. Cuttbow hybrids, the cross between cutthroat and rainbow, are abundant and often the heaviest fish in the lake. Brook trout are present and also reach unusual size here. The fishery is sustained by a long-running state hatchery and trapping programme on the inlet streams. Most of the fishing is done from a boat, float tube or pram rather than from the bank, and the productive water is often surprisingly close to shore.
Idaho applies special regulations to Henrys Lake, including a distinct season and gear rules, and reading them before arriving is essential.

Access
Henrys Lake State Park - the developed access on the southeast shore, with a ramp, camping and parking.
Idaho Fish and Game access areas - several public launches and shoreline points around the lake.
Island Park - the nearest service centre, with lodging, fuel, fly shops and guides.
Targhee Pass - the route east to West Yellowstone, minutes away.
West Yellowstone, Montana - the regional hub for guides, shops and lodging.
Henrys Fork of the Snake River - the celebrated river fishery immediately south.
Hebgen Lake - the large Montana stillwater over the pass, a good alternative in wind.
Seasons
Spring: the season opens with cold, clear water and cruising fish in the shallows, and this is prime time for the largest trout.
Summer: weed growth peaks and damselfly and leech patterns fished over the vegetation do the work, with early and late the best hours.
Fall: cooling water brings fish back shallow and aggressive, and the autumn fishing rivals the spring.
Winter: the lake freezes hard and the regular season is closed, so check the current rules before planning anything.
