Water storages reporting to the Bureau of Meteorology, Australia
liveThe stations of the Bureau of Meteorology's Water Data Online that report the Storage Volume parameter, one row per storage, with the Bureau's station number and name, the data owner and its state or territory, latitude and longitude, the full and dead storage volumes and levels the owner supplied, and the Water Regulations 2008 clause the reporting falls under.
Also called: List of dams in Australia with capacity, Dam capacities Australia, Water storage stations Bureau of Meteorology.
- What is this list?
- Every station that reports a storage volume to the Bureau of Meteorology's Water Data Online, about 570 stations on dams, weirs and reservoirs, with the owner as the Bureau labels it, the state, coordinates, the full and dead storage volumes in megalitres and the full and dead storage levels in metres where the owner supplied them, and the regulation clause the data is reported under. A large dam can have more than one station, as Lake Argyle has several.
- Why do some storages have no capacity?
- About a third of the stations carry no full storage volume in the Bureau's attributes, mostly small or minor storages. The cells are null. The daily volumes for every station are in the companion dataset of daily water storage levels.

Use it in Excel, R, Python and more
Excel and Power BI read the CSV from its address and refresh from it. The R and Python packages take any dataset on this site by its slug, so a new dataset needs no new release. The DuckDB file attaches read-only over HTTPS, and a query reads only the blocks it touches.
The dated URL in the code never changes. https://publicdata.au/d/au-water-storages/latest/ redirects to the newest version.
https://publicdata.au/d/au-water-storages/latest/data.csvIn Excel choose Data, then From Web, and paste this address. Excel keeps it, so Refresh All reads the newest version. A sheet holds about a million rows; past that, load the query to the Data Model.
https://publicdata.au/d/au-water-storages/latest/data.csvIn Power BI Desktop choose Get data, then Web, paste this address and choose Anonymous when asked how to sign in. A scheduled refresh reads the same address, so the report follows each new version.

Query it without downloading
The query API returns only the rows you ask for, as JSON, NDJSON or CSV, from the same typed rows as the files. It needs no key. Build a query here and run it, then copy the URL or the code into your own work.
How filters work
Each filter is field=operator.value in the query string, and every filter must match. A number or date field compares as a number or date, and a text field compares as text. Values are case-sensitive except with ilike. Prefix not. to negate a filter, as not.eq.value.
| Operator | What it matches |
|---|---|
| eq.value | Equal to the value. |
| neq.value | Not equal to the value. A blank cell does not match. |
| gt.value | Greater than the value. |
| gte.value | Greater than or equal to the value. |
| lt.value | Less than the value. |
| lte.value | Less than or equal to the value. |
| like.*text* | Matches a pattern where * stands for any run of characters. Case-sensitive. |
| ilike.*text* | The same as like, ignoring case. |
| in.(a,b,c) | Equal to any value in the list. A value cannot contain a comma. |
| is.null | Blank in the source, or suppressed by the publisher. |
| Parameter | What it does |
|---|---|
| select | Fields to return, comma-separated. Every field when absent. |
| order | field.asc or field.desc, comma-separated. The publisher's row order when absent. |
| limit | Rows per page, 1 to 10,000. 100 when absent. |
| offset | Rows to skip. The next URL in each answer sets it for you. |
| group | On aggregate, fields to group by, comma-separated. |
| metric | On aggregate, count, sum.field, avg.field, min.field or max.field, comma-separated. count when absent. |
| format | json, ndjson or csv. JSON carries the provenance header, and the others carry it in response headers. |
Without a version the API answers from the newest loaded version, and that answer changes when the publisher releases again. Put versions/<date>/ before rows or aggregate for an answer that never changes. /api/v1/datasets/<slug>/versions lists the loaded versions. The 1 newest version is loaded; versions lists them.
The API allows 60 requests in 10 seconds from one address. Above that it answers 429 for 10 seconds with a Retry-After header, a RateLimit-Policy header and a JSON body that gives the limit. Every API answer carries the same RateLimit-Policy. A client should wait the Retry-After seconds, or read the files, which have no limit. openapi.json describes this dataset's query paths for client generators and agents.
https://publicdata.au/mcp is a remote MCP server over Streamable HTTP with the same tools, defined in the same place, so a tool added to the pages is added here too. It needs no key and no account. The row tools are held to the query API's limit of 60 queries in 10 seconds from one address, and each call is two queries because it also counts the matching rows. Add it to Claude Code with claude mcp add --transport http publicdata https://publicdata.au/mcp, add the URL in Claude as a custom connector, or give it to any client that connects to remote MCP servers. Each queryable dataset is also a resource at https://publicdata.au/d/<slug>/fields.json, which lists its fields with their types, the publisher's descriptions, their ranges and the values they hold, so an agent can read a dataset's shape before it writes a query.

Questions
How do I download Water storages reporting to the Bureau of Meteorology as a CSV file?
Open https://publicdata.au/d/au-water-storages/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/au-water-storages/v/2026-10-01/data.csv today. The same path serves Excel, JSON, GeoJSON, Parquet, SQLite, DuckDB, GeoPackage, GeoParquet, NDJSON, Arrow. A dated URL never changes, so use it when the file must stay the same.
Can I open Water storages reporting to the Bureau of Meteorology in Excel?
Yes. https://publicdata.au/d/au-water-storages/v/2026-10-01/data.xlsx is a workbook with the 568 rows on a records sheet, the field list on a second sheet and the provenance on a third. The CSV also opens in Excel. https://publicdata.au/d/au-water-storages/v/2026-10-01/data.csv.gz is the CSV at about a tenth of the size.
How often is Water storages reporting to the Bureau of Meteorology updated?
BoM releases it weekly. This site checks the portal every week and adds a dated version when the file changes.
Can I use Water storages reporting to the Bureau of Meteorology commercially?
Yes. CC BY 3.0 AU allows commercial use, redistribution and derived works as long as the attribution is kept. The attribution string is in this page's side column and inside every file.
Is this the official source for Water storages reporting to the Bureau of Meteorology?
No. The publisher is Bureau of Meteorology, and its page is https://www.bom.gov.au/waterdata/. This site republishes the publisher's file without changing its content. The original sits beside every version as source.csv with its SHA-256, so the two can be compared.
What coordinate system does Water storages reporting to the Bureau of Meteorology use?
Latitude and longitude in decimal degrees as the Bureau publishes them. The GeoJSON file uses the same coordinates, which is what GeoJSON expects.
Which SA2, council area, suburb, postcode, state electorate and federal electorate is each row of Water storages reporting to the Bureau of Meteorology in?
Each row with coordinates carries the SA2 (2021), Council area (LGA 2025), Suburb or locality (2021), Postcode (postal area 2021), State electorate (2025) and Federal electorate (2025) its point falls in, with the code of each. This site joins them by location against the ABS boundaries, https://publicdata.au/d/abs-sa2-2021/, https://publicdata.au/d/abs-lga-2025/, https://publicdata.au/d/abs-suburbs-localities-2021/, https://publicdata.au/d/abs-postal-areas-2021/, https://publicdata.au/d/abs-state-electoral-divisions-2025/, https://publicdata.au/d/abs-federal-electoral-divisions-2025/, and BoM did not publish them. The schema marks each one as joined and names the boundary version. A row without coordinates, or a point outside every area, has them blank. Place columns from Australian Statistical Geography Standard (ASGS) Edition 3 boundaries, Australian Bureau of Statistics, licensed under CC BY 4.0.
What this site did to the data. Cells were typed, headers were renamed and the encoding was made UTF-8. Rows were left alone. The publisher's file sits beside every version as source.csv so the change can be checked.
