Your street may differ: each report covers a reservoir or tower and the area it feeds, and higher streets lose water first. What JW's words mean
Day by day
In 2026 so far: 13 days short of water for Crown Gardens Tower, from 185 days with a report; 12 days for Crown Gardens Reservoir, from 185. A typical supply in the city, the median one (half had fewer), had 4 days.

A day counts as short of water when JW's worst report for it that day was “poor pressure to no water” or “critically low”, as happening or expected (expected most often means higher streets). A warning that it may occur does not count.
In short
The latest JW report on this site is from 29 September 2026; the site last read JW's website on 1 October. Crown Gardens Tower was supplying fairly. Crown Gardens Reservoir closed overnight on purpose. This year Crown Gardens Tower was short of water on 13 of the 185 days JW reported it. A typical reservoir or tower in the city had 4 such days. On Crown Gardens Tower, half of its last 8 outages were over within 30 hours; the longest since March 2025 lasted 3.8 days. No JW notice we have read names Crown Gardens Tower.
On JW's list of towers, June 2024, as Evans Park. Source 1 ↗
Outages
JW reported 15 outages on Evans Park's supplies since March 2025. The longest lasted 3.8 days. Every outage, with how long it lasted: Crown Gardens Reservoir and Crown Gardens Tower.
JW's end dates
JW posted 17 notices with an end date that list a suburb or system Evans Park's supplies feed. Most name only suburbs, not the reservoir or tower, so the summary at the top uses only a notice that names the supply itself. By the stated time JW's boards showed the water back on none of the 12 end times that have passed. Each end date against what happened: Crown Gardens Reservoir and Crown Gardens Tower.
Under strain
In 2026 so far, Evans Park had 42 days under strain: days when JW reported any of its supplies low or worse, or warned that higher-lying areas may lose water. This is a wider count than days short of water.
The network is linked. Evans Park draws on all its supplies at once, and when one runs low the others carry more. At such times JW's boards sometimes warn of “poor pressure to no water in higher-lying areas”: under strain, higher streets lose water first. JW does not say which streets those are.
What JW's boards cannot tell you
JW's boards report reservoirs and towers, so some things are not in this record:
Whether water reaches your street or your tap.
Which streets lose water first: JW warns of higher-lying areas but does not name the streets.
Why a supply ran low, unless a JW notice gives a reason.
Pipe bursts, tankers and valve work, which are not on the boards.
