Diamond Lake Webcam – Oregon’s Lake Between Two Volcanoes

The Diamond Lake Webcam looks out over Diamond Lake from the shore at Diamond Lake Resort, high in the Umpqua National Forest of southern Oregon. A stand of tall conifers on a point fills the left of the frame, open water stretches away to the right, and a metal dock frame with a small red flag sits in the foreground. The lake lies at 1,580 meters (5,183 feet) between two volcanic peaks, Mount Bailey to the west and Mount Thielsen to the east, and the weather up here turns quickly. In late autumn, snow squalls and low cloud can swallow the far shore in minutes, while in midwinter the surface freezes over. It is a quick way to check conditions before driving up Highway 138.

About Diamond Lake

Diamond Lake covers about 12.3 square kilometers (3,040 acres) and runs 5.6 kilometers (3.5 miles) from end to end and 2.4 kilometers (1.5 miles) across. For its size it is shallow: the average depth is 7.3 meters (24 feet) and the deepest point only 16 meters (52.5 feet). Mount Thielsen, on the east side, tops out at 2,799 meters (9,184 feet), while Mount Bailey, on the west side, reaches 2,553 meters (8,375 feet). Trails climb to both summits, and the Pacific Crest Trail passes nearby.

The lake takes its name from John Diamond, who saw it in 1852 from the summit of the peak that now also carries his name, Diamond Peak. Diamond Lake Resort opened in 1922, and a post office named Diamond Lake followed in 1925. The resort still runs a lodge, more than 30 cabins, a motel and an RV park with 110 full hookup sites, in a recreational partnership with the Umpqua National Forest. The Diamond Lake Webcam feed appears on the resort’s conditions page, next to its weather readout.

Fishing shaped much of the lake’s modern story. Rainbow trout are not native here, because the lake lacks good spawning habitat, and Oregon began stocking a Canadian strain in 1954. Illegally introduced tui chub turned up in 1992, and a rotenone treatment in 2006 killed about 95 million of them. Brown trout have been stocked since 2018 to prey on any chub and golden shiners that remain.

Weather and Climate in Diamond Lake

At this height winter is long and cold. From December through February, afternoons typically reach only about 3°C (37°F), and nights fall to around -4°C (25°F) or lower. December is usually the wettest month. Once the lake freezes over, the camera can show a frozen, snow-covered surface instead of open water, and snowmobiles and cross-country skis take over from the boats. November is a transition month, with rain, sleet and snow squalls rolling across the water, and the far shore can vanish behind falling snow even at midday.

Spring arrives slowly, and April afternoons still average only about 8°C (46°F). Summer is short, warm and dry: July and August afternoons average around 25°C (77°F), nights drop to about 10°C (50°F), and July sees very little rain. That is the season when boats can appear on the water and the trail around the shore is busy with walkers and cyclists. By October, highs fall back to about 13°C (56°F), and nights drop to around 3°C (37°F).

Things to Do Near Diamond Lake

In summer, the Marina Store at the resort rents pontoon boats, fishing boats and paddle boats, along with mountain bikes for the trail around the lake, which runs about 18 kilometers (11 miles) and is mostly paved. Anglers fish from the shore or from boats for rainbow trout, which may be kept, while brown trout and tiger trout had to be released under the 2025 rules. Forest Service campgrounds line the shore, including Diamond Lake Campground with 240 sites, Broken Arrow with 148 and Thielsen View with 58. The Mount Thielsen trailhead sits just off Highway 138 near the lake.

Winter brings a different set of activities. The resort runs a snow tubing hill with eight lanes and a 143-meter (470-foot) conveyor carpet lift, and tickets are sold online only. Snowmobiles can be rented at the resort, and cross-country skiers and snowshoers have 11 kilometers (7 miles) of groomed trails plus more than 56 kilometers (35 miles) of backcountry. When the lake freezes, ice fishing is a bring-your-own-gear affair, and guided snowcat skiing on Mount Bailey is listed among the resort’s winter trips. The boundary of Crater Lake National Park is 8 kilometers (5 miles) south of the resort. Crater Lake is the deepest lake in the United States at 592 meters (1,943 feet), and its Rim Drive loops 53 kilometers (33 miles) around the caldera.
