Dade Lake
Lake · 11,591 ft · Mammoth Lakes corridor
Dade Lake sits at 11,591 feet in the Mammoth Lakes corridor of the Sierra Nevada, a high-alpine cirque lake exposed to afternoon wind. Winter approach requires avalanche awareness; summer offers a calm, less-visited alternative to busier basin lakes.
Dade Lake experiences classic high-Sierra afternoon wind acceleration, with gusts climbing into the upper 30s mph by mid-day. Morning calm typically holds until mid-morning. The lake's exposure and elevation mean temperature swings are sharp; expect single-digit to low-20s Fahrenheit through the rolling season.
Over the last 30 days, Dade Lake averaged a NoGo Score of 37.0 with wind holding at 13 mph average and temperatures around 18 degrees Fahrenheit. The week ahead will track similar patterns: watch for afternoon wind pulses and keep avalanche terrain in mind if approaching via steep snow gullies. Late-season snowpack remains variable; stability intel from the Eastern Sierra Avalanche Center is essential before any winter or spring visit.

About Dade Lake
Dade Lake is a small, high-elevation cirque lake in the Mammoth Lakes backcountry, situated at the head of a drainage system that feeds into the June Lake Loop corridor. Access is via trailhead routes from the Mammoth Lakes area; the primary approach follows established tracks from near June Lake or the Reversed Creek drainage. Highway 395 provides the primary corridor access to Mammoth, roughly 40 minutes from Lee Vining. From town, roads climb quickly into the high country; expect rough, rocky terrain once off pavement. The lake sits above 11,500 feet and is snow-bound in winter and early spring.
Wind patterns at Dade Lake are predictable but unforgiving. The 30-day rolling average wind of 13 mph masks stronger afternoon funneling; peak gusts have reached 39 mph in the rolling season. Temperatures range from a 365-day low of 4 degrees Fahrenheit to a high of 31 degrees, with typical spring and fall conditions hovering in the upper teens. The lake's small size and steep basin walls create exposure to both temperature fluctuations and rapid wind onset. Morning hours, typically before 10 AM, offer the calmest conditions; skip the lake entirely after 2 PM if you're paddling or doing any exposed activity. The 365-day pattern shows this place is marginal for recreation most of the year; late summer, when snowpack has cleared and afternoon winds are less extreme, provides the easiest window.
Dade Lake appeals to experienced high-country hikers and backcountry skiers willing to navigate avalanche terrain and carry avalanche safety gear in winter and spring. The base popularity rating of 0.25 reflects its remoteness and the technical approach required; few casual visitors reach it. Parking is limited and trailhead access requires high-clearance vehicles in wet or snowy periods. Plan for crowds to be minimal except on rare stable-weather weekends in late summer. Avalanche awareness is non-negotiable: the steep slopes feeding the lake are active terrain in spring, and any approach involving gullies or snow fields requires beacon, probe, and shovel. Water quality and wildlife are typical of high-Sierra lakes; the setting is spartan and rules-based rather than recreational.
Dade Lake sits in the broader Mammoth Lakes corridor and can be paired with adjacent cirques and basins for a longer backcountry mission. The June Lake Loop, 10 to 15 minutes south via Highway 395, offers more established trailhead infrastructure and lower-elevation alternatives when Dade is snow-locked. Gull Lake, Silver Lake, and Tenaya Lake in the same corridor are warmer and more accessible but receive higher use. For serious winter climbing or ski touring, Dade's exposure and technical approach make it a destination for mountaineers; casual day-hikers should defer to lower-basin options with fewer avalanche hazards and more predictable conditions.
