## Query

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. Rows: https://publicdata.au/api/v1/datasets/vic-water-storage-levels/rows. Counts and sums: https://publicdata.au/api/v1/datasets/vic-water-storage-levels/aggregate.

- Rows: https://publicdata.au/api/v1/datasets/vic-water-storage-levels/rows?month_end=eq.2025-09-30&limit=5
- Aggregate: https://publicdata.au/api/v1/datasets/vic-water-storage-levels/aggregate?group=reservoir&metric=sum.storage_ml&month_end=eq.2025-09-30

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`. Operators: `eq.value`, `neq.value`, `gt.value`, `gte.value`, `lt.value`, `lte.value`, `like.*text*`, `ilike.*text*`, `in.(a,b,c)`, `is.null`.

- `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 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.

## Questions

### How do I download Monthly water storage levels as a CSV file?

Open https://publicdata.au/d/vic-water-storage-levels/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/vic-water-storage-levels/v/2025-10-31/data.csv today. The same path serves Excel, JSON, Parquet, SQLite, DuckDB, NDJSON, Arrow. A dated URL never changes, so use it when the file must stay the same.

### Can I open Monthly water storage levels in Excel?

Yes. https://publicdata.au/d/vic-water-storage-levels/v/2025-10-31/data.xlsx is a workbook with the 12,474 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/vic-water-storage-levels/v/2025-10-31/data.csv.gz is the CSV at about a tenth of the size.

### What years does Monthly water storage levels cover?

The current version covers 2010 to 2024. Each release from DEECA becomes a new dated version here, and earlier versions stay online.

### How often is Monthly water storage levels updated?

DEECA releases it monthly. This site checks the portal every week and adds a dated version when the file changes.

### Can I use Monthly water storage levels commercially?

Yes. CC BY 4.0 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 Monthly water storage levels?

No. The publisher is Department of Energy, Environment and Climate Action, and its page is https://discover.data.vic.gov.au/dataset/regional-melbourne-and-all-victoria-monthly-water-storage-levels. This site republishes the publisher's file without changing its content. The original sits beside every version as source.xlsx with its SHA-256, so the two can be compared.

### What does each row hold?

The volume of water, in megalitres, held in one reservoir at the end of one month, for every reservoir the department reports across Melbourne, Geelong, Ballarat, Bendigo and the regional systems, from January 2010. The reservoir's total capacity and system are in the companion dataset of Victorian water storages, so a percentage full can be worked out by joining the two.

### Why are some cells null?

The publisher leaves a cell blank where a reservoir's volume was not available for that month, and a reservoir that entered the report later has no earlier rows. The blanks are kept as null.

### How often does it change?

The department adds a month to the spreadsheet about a month after it ends. Each release replaces the file, so each version here is one release, and the portal record may lag the file by a few weeks.

## What this site did to the data

Cells were typed, headers were renamed to snake_case and the encoding was made UTF-8. Rows were left alone. Nothing is derived. The publisher's file is beside every version as `source.xlsx`.
