With the Kishon River Authority

Kishon River

14 years of water data in one platform, and an early warning that sees low-oxygen events coming.

Context

The Kishon River Authority manages the restoration of the Kishon, a river people return to for rowing and recreation.

Challenge

Years of measurements were spread across separate files and formats.

Sampling follows a monthly calendar, so short events between samples, like night-time oxygen lows, can pass unseen.

What we did

We brought 14 years of water data (2012–2025) into one platform.

Every measurement is scored against 5 water-quality standards: bathing, boating, ecological status, the Authority's own Kishon standard, and the NSF Water Quality Index.

We then back-tested a simple trend warning on 2025 continuous oxygen data.

water-quality standards scored on every measurement: bathing, boating, ecological status, the Kishon standard, NSF-WQI.

7 of 10

low-oxygen events in 2025 flagged by a trend warning, about 3 days ahead. Monthly sampling caught none.

Back-test on 2025 data. Early-warning service in development with the Authority.
