My Edit Page First of all, I will be Editing / Updating this section on a ? basis, keep an eye on it.

Snowy Mountains Scheme.
The File : File:Snowy-Mountains-System (de).png is incorrect Tumut 1 & 2 are labelled in reverse,

Separating of the 3 Tumut Hydroelectric Power Stations.

 * Separating of the 3 Tumut Hydroelectric Power Stations, Good / Great Idea, they are Individual Entities, 1 per ?.
 * Murray Hydroelectric Power Station as well !

There are 5 Hydroelectric Power Stations located along the Tumut River or System,
 * 4 of the 5 are part of the Original Scheme,
 * 4 of 7 in the Original Snowy Mountains Scheme, now 9,
 * 2 of the 3 Tumut's are Underground,
 * 3 have Tumut in their Name along with 2 of the more than 5 Dams / Reservoirs or Ponds / Pondages & Weirs etc.

I believe the 3 Tumut's should be all separated to individual pages but as part of a Hierarchical description of the system, Starting with an overall view, then 2 Areas : Northern & Southern, then Sub Areas as required, then Individual ? I also believe that the Murray Hydroelectric Power Station should be separated as well. Murray Hydroelectric Power Station.

Lift & Ventilation Shaft has be added & is @ 35°57'08.1"S 148°22'02.9"E as part of my Tumut 1 / 2 Geograpy / Location shift & Wikidata Update.

"Upper Tumut Power Station is sometimes used as a colloquial term to refer to both Tumut 1 and Tumut 2 Underground Power Stations." apart from "1 thing in Common ?" "The station is connected to the National Electricity Market via the 330KV Upper Tumut Switching Station, 2.75 kilometres (1.71 mi) North of Cabramurra." This is where the confusion might be ? I deleted a set of Coordinates from there as they were wrong for 1 of the 2 Tumut's & the other Tumut was located wrongly.
 * This statement should also be removed from Tumut 1, they are 2 separate Entities 8.7 km apart, I have never heard them referred to as Upper Tumut Power Station.

Geography
Bounded by The Catchments of ; Goodradigbee River above the Goodradigbee River Weir Intake & ? other small Intakes on the Goodradigbee Aqueduct in the N/E toward, Tantangara Dam Wall on the Very Upper Murrumbidgee River Catchment in the East, Eucumbene Dam as a Major Storage Dam in the Upper Eucumbene Catchment, an ? Mowamba River Weir & Aqueduct back to Jindabyne Dam Wall on the Lower Eucumbene / Upper Snowy River Catchment Junction &/or Jindabyne Mini / Micro Hydro in the S/E, Lady Northcote Ck Intake & other Multiple Intakes on the Geehi Aqueduct & Middle Ck Intake & Aqueduct back to the Geehi River above the Geehi River Dam Wall & 2 Cascade Ck Intakes + 2 other & Bogong Ck Intake into a combined Bourkes Gorge Intake in the South on the way to, Murray 2 Pondage / Power Station &/or Khancoban Dam Wall @ the bottom of the Murray System in the S/W, Tooma Dam Wall & Intake & 5 other Intakes in the West & into Tumut System & Blowering Power Station @ the bottom of the Tumut System in the N/W.

The Original Snowy Mountains Scheme had 2 distinct areas : Northern & Southern, these can be further broken down into Sub Areas ;

Northern :
 * Murrumbidgee - Eucumbene, Starts @ the Goodradigbee Weir to Eucumbene Dam Wall to Tooma Catchment above the Aqueduct & Intakes


 * Murrumbidgee - Blowering / Future Snowy 2.0 Pumped Storage


 * Eucumbene - Tumut

Above the dam wall some water is diverted into the Tooma - Tumut Aqueduct Tunnel along with 5 other Intakes (Outstation Ck, Ogilvies Ck, Deep Ck, ? Ck & Burns Ck) on the Aqueduct Tunnel for Storage in Tumut & Use in the 5 Tumut River Hydroelectric Power Station System.
 * Tooma - Tumut

Southern : A 2 Way Tunnel
 * Eucumbene - Snowy


 * Guthega

Jindabyne - Snowy A Pumped


 * Snowy - Murray,

Murray System starts @ the Jindabyne Dam Pumping Station, up & underneath Island Bend Intake & through to & into Geehi Reservoir for storage.

Upper Snowy Mountains Scheme Catchments. One part starts on the Upper Goodradigbee River, (a tributary of the Murrumbidgee River just above the Burrunjuck Dam Wall) on the Western side of the Australian Capital Territory where the Goodradigbee Weir & Aqueduct diverts a limited amount of water with further intakes along the way through a Water Meter into the Upper Murrumbidgee River Catchment above Tantangara Dam or Reservoir for storage. This then is diverted as required to Eucumbene Dam or Storage Reservoir in the Upper Eucumbene River Catchment for distribution as required.

Other Inputs are from the combined Gungarlin & Burrungubugee River Weirs above this junction & above the junction with the Snowy River through a 2 way Tunnel back to Eucumbene Dam or Storage Reservoir.

From here it can go 1 of 2 ways with Further Water Inputs along the way ;

Snowy - Tumut System or the Snowy - Murray System. These are 2 of 3 separate systems under the Snowy Mountains Scheme, the other 1 is above.

Snowy - Tumut System.

Inputs ; Happy Jacks, Very Upper Tumut River & from the Upper Tooma River Catchment with Inputs (all tributaries of the Murray River)

Tumut 1 Pond

Tumut 1 Underground Hydroelectric Power Station The station is connected to the National Electricity Market via the TransGrid 330KV Upper Murray Switching Station & 330/132KV Substation, 1.56 kilometres (1.71 mi) North of Cabramurra.

Upper Tumut Power Station is sometimes used as a colloquial term to refer to both Tumut 1 and Tumut 2 Underground Power Stations.

Located downstream of Tumut Pond Dam and 366 metres (1,201 ft) below ground level,[2] Tumut 1 Power Station is situated approximately 2.25 kilometres (1.40 mi) south-west from Cabramurra, under Happy Valley Rd. A Combined 380M / 1250' Lift & Air Ventilation Shaft [1] are on Happy Valley Rd. It may also be worthwhile noting that, at the time of construction and commissioning, T1 had the longest single-travel elevator (lift) in the southern hemisphere, at something around (380M) 1250 feet from top landing to bottom level within the power station below. This elevator is now used only as an emergency means of exit from the station; it was originally intended to be used for access as well, when it was thought that T1 would host tourist groups. That idea never eventuated.

There is a further Intake @ Bogong Ck, Burkes Gorge.

These 2 stations are connected to the National Electricity Market via the TransGrid 330KV Murray Switching Station (& the 330/132KV Substation for Guthega Power Station, Jindabyne Pumping Station & Jindabyne Dam Wall Mini Hydro Power Stations), 1.56 kilometres (1.71 mi) South East of Khancoban.

This station is connected to the National Electricity Market via the TransGrid 330/132KV Substation @ the TransGrid 330KV Murray Switching Station, 1.56 kilometres (1.71 mi) South East of Khancoban.

(& the for Guthega Power Station, Jindabyne Pumping Station & Jindabyne Dam Wall Mini Hydro Power Stations)

Weirs, Aqueducts & Intakes
Goodradigbee R Weir & Aqueduct Gungarlin R Weir & Burrungubugge R Weir use the same Intake. Mowamba Ck Geehi Aqueduct has ? Middle Ck 3 + Cascade Ck & Bogong Ck use Bourkes Gorge Intake

QNI
The Queensland – New South Wales Interconnector (QNI) is a 330 kV AC interconnection between New South Wales and Queensland, Australia.

The link was commissioned in 2001. It consisted of double-circuit 330 kV lines between Armidale, Dumaresq, Bulli Creek and Braemar and a double-circuit 275 kV line between Braemar and Tarong.

There is an additional 330KV AC Dual Circuit to compliment the QNI from Bulli Ck Switching Station -27.92111°N, 150.84306°W via Millmerran Power Station & Switching Stations -27.96531°N, 151.27419°W to Middle Ridge Switching Station & 330/275/110KV Sub, South of Toowoomba -27.62283°N, 151.94528°W. There is also a Sapphire Wind Farm Electrical Substation @ -29.69953°N, 151.41261°W in 1 of the 2 330KV AC Dual Circuits between Armidale & Dumaresq, 31.73 KM West of Glen Innes, New South Wales.

The original maximum transfer capacity was 300 to 350 MW in both directions. This has been progressively increased to 700 MW from New South Wales to Queensland and 1,200 MW from Queensland to New South Wales.

The interconnector is operated by TransGrid and Powerlink Queensland.
