Adobe Reservoir
Lake · Mammoth Lakes corridor
Adobe Reservoir sits at 6693 feet in the Mammoth Lakes corridor of the Sierra Nevada, a glacially-fed alpine lake typically calmer than the exposed waters just east and accessible year-round via Highway 395.
Wind averages 14 mph across the 30-day window but funnels harder by mid-afternoon, particularly when cold air drains off the high peaks to the west. Morning conditions are markedly steadier. Expect afternoon gusts to exceed the average by a significant margin.
Over the past 30 days, Adobe Reservoir has averaged a NoGo Score of 14 with wind at 14 mph and temperatures around 45 degrees Fahrenheit. The rolling 30-day maximum wind reached 43 mph, typical of spring storm pulses in the high Sierra. The week ahead will track seasonal patterns of early-morning calm followed by afternoon loading.

About Adobe Reservoir
Adobe Reservoir lies in the Mammoth Lakes corridor at 6693 feet, accessed primarily via Highway 395 from the south or north. The lake sits in a basin drained by Mammoth Creek, roughly 5 to 10 miles south of the town of Mammoth Lakes. A secondary approach comes from the west via Highway 203 and local roads, though snow blocks these routes until late spring. The reservoir itself is modest in size but sits in a semi-protected drainage, making it a quieter alternative to the larger waters further north.
Conditions at Adobe Reservoir are driven by Sierra drainage winds and the lake's semi-enclosed setting. The 30-day average temperature stands at 45 degrees Fahrenheit with an average wind of 14 mph; however, afternoon heating and pressure gradients routinely push gusts to 25 to 35 mph by late day. Winter and early spring (through April) bring the most volatile weather, with the rolling 30-day maximum wind of 43 mph typical during transition storms. Crowding averages 4 on the 10-point scale, making weekday visits noticeably quieter than weekends. Late September through early November and again in May offer the most stable wind windows.
Adobe Reservoir suits paddlers, anglers, and day-use visitors seeking a less-trafficked high-Sierra lake. The semi-protected drainage means morning paddlers can expect 30 to 60 minutes of workable conditions before afternoon wind becomes dominant. Anglers targeting the early season should plan for cold water and expect snow and ice margins through mid-May depending on the year. The 6693-foot elevation means afternoon thunderstorms are a real hazard in summer and fall; head out early and off the water by mid-afternoon. Parking is limited, and weekend mornings can fill quickly.
Nearby Crowley Lake and Convict Lake sit further north and tend to be more exposed to afternoon wind and more crowded on weekends. Mammoth Creek itself offers quieter tributary access if higher flows permit. The town of Mammoth Lakes, 5 to 10 miles north, serves as the primary gateway for fuel, food, and lodging. Highway 395 remains open year-round, though expect winter chains or all-wheel drive requirements from December through March.
