Recreational lakes and rivers water quality, ACT, 2019-20 season
liveThe results of ACT Health's recreational water quality monitoring at 17 swimming sites on Lake Ginninderra, Lake Tuggeranong, the Molonglo at its water ski ramp, Paddys River and the Murrumbidgee for the 2019-20 swimming season. Each row carries the publisher's row identifier, the sample date, the site code and name, the intestinal enterococci result, whether it complied, the algae result, the final compliance, any comment and the point's longitude and latitude.
Also called: ACT Recreational Lakes and Rivers Compliance 2019-20, Canberra swimming water quality 2019-20, Murrumbidgee River swimming water quality 2019-20.
Part of Recreational water quality at ACT lakes and rivers, 2 tables the publisher releases together: Recreational lakes and rivers water quality, ACT, 2018-19 season.
- What is in each row?
- One weekly sample at one swimming site during the 2019-20 season, with the site code and name, the intestinal enterococci result per 100 millilitres, whether it met the guideline, the algae result and final compliance where recorded, any comment, and the site's coordinates.
- What do NS and NR mean in the result?
- They are the publisher's codes for a site not sampled or a result not recorded that week. A result above or below the laboratory's range is written with a greater than or less than sign. The result is kept as text so these survive. The publisher marks some unsampled weeks as meeting the guideline and some as not, so leave them out before counting results.
- Are later seasons here?
- No. The publisher's tables for the 2021-22 season onwards state no licence on the portal, so they are not republished here.

Download it as Excel, CSV, JSON and 9 more formats
Pick a format and a version. Excel is picked first because it opens in the tools most offices have. The URL is yours to keep. A dated version never changes.
In your own tools
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/act-recreational-water-quality-2019-20/latest/ redirects to the newest version.
https://publicdata.au/d/act-recreational-water-quality-2019-20/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/act-recreational-water-quality-2019-20/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.
