NSW storages are 62.6% full (13,743 GL of 21,944 GL), down 0.5 points in a week; a year ago the same 53 storages were 67.1% full.
57 storages reporting to the Bureau of Meteorology, latest reading 2026-09-27 23:45. Refreshed every 30 minutes.
This table lists every New South Wales storage that the Bureau of Meteorology publishes, from Warragamba and the other Greater Sydney dams to the irrigation dams of the inland valleys. Each row shows accessible volume, per cent full, level and the change over seven days, and the storages open to anglers link to their fishing page on this site.
Percentage full is the Bureau’s accessible volume divided by the accessible capacity, as on its storage dashboard, so it can differ by a point or two from the operator’s daily report, which is the official figure. Year ago is the same storage on the same date last year. Dams with a fishing page link to it.

WaterNSW runs the Greater Sydney dams in this table, among them Warragamba, Avon, Cataract, Cordeaux, Nepean and Woronora, and the regional dams from Pindari and Copeton in the north to Blowering and Burrinjuck in the south. Hunter Water reports the storages of the Lower Hunter, and the Bureau lists the Gosford and Wyong councils as the supplier for Central Coast storages such as Mangrove Creek Reservoir. Snowy Hydro Limited supplies figures for the storages of its scheme. On the Murray, the Murray–Darling Basin Authority operates the river system to the South Australian border and decides each day how much to release from Hume Dam and the other shared storages. All of these bodies send their readings to the Bureau, and the table here takes them from the Bureau in one standard format.
The Bureau reports accessible volume: the water held between the minimum supply level, set by the lowest outlet, and the full supply level, the normal top of the storage when no flood is passing. Water below the lowest outlet is dead storage and is left out, so 0 per cent in this table means the outlets have nothing left to draw, not a dry lake bed. WaterNSW also reports accessible volume, and the Bureau puts the small differences between the two down to report timing, rounding and smoothing. Levels are another matter: the Bureau gives each one in metres above the Australian Height Datum, close to mean sea level, whereas the Sydney figures have been published as a distance below full supply level, so a level here is an elevation, not a depth.
WaterNSW publishes its own Greater Sydney total every day, and for operating questions, such as whether a dam is spilling or releasing, its pages are the reference. The Bureau’s figure is a standardised national record built for comparing storages and regions, and its latest reading is usually from yesterday or the day before. The Bureau also notes that it may not have every rule needed to reproduce exactly how a city system’s total is calculated. Warragamba is, in WaterNSW’s words, the primary supply for Greater Sydney, and its flood fact sheet explains that it is operated as a water supply dam, not a flood mitigation dam, so no room is made ahead of forecast rain. Once it is full, small releases keep it just below 100 per cent rather than the radial gates opening for every small rise, and outside floods the level may be drawn down by up to a metre for maintenance.
A storage can show more than 100 per cent, and the Bureau’s glossary gives floods as the usual cause: water rises above full supply level on its way over the spillway. When the Bureau adds storages into regional totals, it treats that extra water as in transit and caps each storage at its capacity. The opposite also happens. After an earthquake risk assessment, Hunter Water reduced the top water level at Grahamstown Dam in 2024, first to 89 per cent and then to 82 per cent of capacity, while it plans upgrades to the embankments. A Grahamstown reading near that mark therefore reflects a safety limit rather than a shortage of rain; Hunter Water also notes that its shallow storages lose water quickly to evaporation in hot, dry spells.
Within the Greater Sydney drinking water catchment, land and water storages are declared Special Areas under the Water NSW Act 2014, and public entry is prohibited or limited to walking. Hunter Water likewise allows no public access onto Grahamstown or Chichester dams, only to the picnic areas beside them. The Sydney-region exceptions sit in the Shoalhaven scheme: WaterNSW sets aside a land-based fishing area for trout and bass on the eastern foreshore of Fitzroy Falls Reservoir, where boating and swimming are not allowed, and Lake Yarrunga behind Tallowa Dam is used for canoeing and fishing, although the dam road is closed until mid-2027 and access to the lake is restricted when the dam spills. Inland, the irrigation dams are the angling water; WaterNSW’s page for Burrendong names redfin, golden perch, Murray cod, silver perch and catfish. DPIRD only takes nominations for new stocked impoundments where practical public access exists and fishing is allowed, and the NSW Recreational Fishing Fee, from A$7 for three days, applies on every one of them.
A falling level on an inland dam usually means water is being released for irrigation, stock and towns downstream. For anglers it lengthens the walk to the water, brings snags and rock bars closer to the surface and can leave the end of a ramp short of the edge. A sharp rise after rain brings muddy inflow and floating timber, and releases below the wall. WaterNSW’s page for each dam lists its boat ramps and their limits; at Burrendong, for example, the public ramps are at the holiday parks and there is no lake access via the WaterNSW ramp. Recreation areas at WaterNSW dams close on every total fire ban day, and its Early Warning Network sends dam and release notifications to anyone who registers.
Each Greater Sydney storage has a row with the volume, fullness, level and weekly movement last reported to the Bureau of Meteorology, normally a reading taken one or two days earlier. WaterNSW’s Greater Sydney page gives the operator’s combined figure, updated daily.
Every New South Wales storage the Bureau publishes is in the table, from the Sydney and Hunter supply dams to the northern and southern valley storages. For a summary by valley, WaterNSW’s regional dam levels page groups the inland dams into Northern, Coastal, Central and Southern.
Both report accessible volume, so the differences are small: the timing of each report, rounding and the smoothing of data, according to the Bureau. The Bureau also says it may not be able to reproduce a city system’s total exactly, so the Greater Sydney figures can differ slightly.
WaterNSW, Hunter Water, the Central Coast councils, Snowy Hydro and the other operators send their readings to the Bureau of Meteorology, which standardises them to accessible volume and to metres above the Australian Height Datum. This page reads the Bureau’s published figures.
No. WaterNSW allows no access to restricted and Special Areas around Warragamba, and visitors are limited to the visitor centre, lookouts and, on weekends and public holidays, part of the dam wall. Fitzroy Falls Reservoir and Lake Yarrunga are the nearest WaterNSW storages where fishing is allowed.
