Question: The Snowy Mountains, located in southern New South Wales, contain which major gated earthfill embankment?
Context: Geehi Dam is a major ungated rockfill embankment dam with an uncontrolled "glory hole" spillway across the Geehi River in the Snowy Mountains of New South Wales, Australia.  The dam's main purpose is for the generation of hydro-power and is one of the sixteen major dams that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro. The Blowering Dam is a major ungated rock fill with clay core embankment dam with concrete chute spillway across the Tumut River upstream of Tumut in the Snowy Mountains region of New South Wales, Australia.  The dam's purpose includes flood mitigation, hydro-power, irrigation, water supply and conservation.  The dam is part of the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro.  The impounded reservoir is called Blowering Reservoir. Jindabyne Dam is a major ungated rockfill embankment dam across the Snowy River in the Snowy Mountains of New South Wales, Australia.  The dam's main purpose is for the generation of hydro-power and is one of the sixteen major dams that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro. Jounama Dam is a major ungated rockfill embankment dam across the Tumut River in the Snowy Mountains of New South Wales, Australia.  The dam's main purpose is for the generation of hydro-power and is one of the sixteen major dams that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro. Eucumbene Dam is a major gated earthfill embankment dam with an overflow ski-jump and bucket spillway with two vertical lift gates across the Eucumbene River in the Snowy Mountains of New South Wales, Australia.  The dam's main purpose is for the generation of hydro-power and is one of the sixteen major dams that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro. Khancoban Dam is a major ungated earthfill embankment dam with a controlled spillway across the Swampy Plain River in the Snowy Mountains region of New South Wales, Australia.  The dam's main purpose is for the generation of hydro-power and is one of the sixteen major dams that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro. The Snowy Mountains Highway is a 333 km state highway located in New South Wales, Australia.  Its two sections connect the New South Wales South Coast to the Monaro region, and the Monaro to the South West Slopes via the Snowy Mountains.  The higher altitude regions of this road are subject to snow over the winter months, and the road also provides access to many parts of the Snowy Mountains Scheme.  The highway bears the B72 shield along its entire length. Tooma Dam is a major ungated concrete embankment dam across the Tooma River in the Snowy Mountains of New South Wales, Australia.  The dam's main purpose is for the generation of hydro-power and is one of the sixteen major dams that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro. Talbingo Dam is a major ungated rock fill with clay core embankment dam with concrete chute spillway across the Tumut River upstream of Talbingo in the Snowy Mountains region of New South Wales, Australia.  The dam's main purpose is for the generation of hydro-power and is the largest of sixteen major dams that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro.  The impounded reservoir is called Talbingo Reservoir. The Snowy Mountains, known informally as "The Snowies", is an IBRA subregion and the highest mountain range on the continent of mainland Australia.  It contains the Australian mainland's highest mountain, Mount Kosciuszko, which reaches to a height of 2228 m above sea level.  The range also contains the five highest peaks on the Australian mainland (including Mount Kosciuszko), all of which are above 2100 m .  They are located in southern New South Wales and are part of the larger Australian Alps and Great Dividing Range.  Unusual for Australia, the mountain range experiences large natural snowfalls every winter.  Snow normally falls the most during June, July and early August.  Therefore, most of the snow usually melts by late spring.  The Tasmanian highlands makes up the other (major) alpine region present in Australia.
