Water Quality Archive (WQA) APIs will be changing
Created: 29 September 2025 Updated: 06 November 2025
Date of Announcement: 27 October 2025
Functionality Affected: Water Quality Archive APIs
Throughout October, we will be intermittently disabling the Water Quality Archive API.
Announcement
We’re upgrading the Water Quality Archive (WQA) on the DSP to improve both the user interface and the API, based on feedback and evolving user needs.
As part of this upgrade, we’ll be replacing the current API, which means the existing version will stop working later this year. We understand the importance of stable, long-term services and don’t take this decision lightly—but this change is necessary to deliver a better experience.
This is to ensure users are aware that they will need to transition to the new API. The dates the API will be unavailable are:
Week commencing 27 October 2025
Tue overnight
Thu 9am - 1pm
Week commencing 03 November 2025
Tue 1pm - 5pm
Thu 1pm - 5pm
Week commencing 10 November 2025
Mon 9am - Tue 9am
Thu 9am - 5pm
Week commencing 17 November 2025
Wed (19th) 9am - Thu (20th) 9am
Fri (21st) 9am - Mon (24th) 9am
Week commencing 24 November 2025
Mon (24 Nov) - Monday (01 Dec)
The new API can be accessed from API Documentation | Water Quality Explorer.
