From April to September 2026 (six months), JW reported Lawley Reservoir short of water on 32 of 164 reported days
Days per month short of water, stacked: critically low at the base. The tick is the median supply in the city that month. The strip under each bar is the share of days with a JW report; a month with none says gap. 3 March 2025 to 29 September 2026.
In 2026 so far: 39 days short of water for Lawley Reservoir, from 194 days with a report. The median supply in the city: 4 days.

On Lawley Reservoir, half of its last 10 outages lasted at least 30 hours
This is not a forecast. It is how long past outages lasted. Each dot is one past outage, placed by its length: the last 10 outages on Lawley Reservoir. A hollow dot with an arrow had no reported end: JW's reports stopped before it ended, or it was still going at JW's last report. Either way it lasted at least that long (5 of 10).

JW's notices gave 3 end times for Lawley Reservoir. By the stated time, JW's boards showed the water back on none of the 3 that have passed
The water came back after the stated time 3 times; half of those times it was back within 13 hours 55 minutes of it. Each row is one end time a JW notice stated for one supply, in date order (hollow dot), against the first board on which JW reported the supply supplying fairly or better and off bypass (filled dot). This asks more than the end of an outage, which comes at JW's first report better than “poor pressure to no water” or “critically low”. An arrow: no such board yet. From 2 notices.

In words
2026 so far: JW reported it at “poor pressure to no water” or “critically low” on 39 days. JW published a report for it on 194 of the 272 days in the record; the other 78 days have no report, and we do not count them as normal. The median supply in the city had 4 such days.
2025: JW reported it at “poor pressure to no water” or “critically low” on 15 days. JW published a report for it on 92 of the 304 days in the record; the other 212 days have no report, and we do not count them as normal. The median supply in the city had 1 such day.
The last 10 outages JW reported on this supply lasted a median of at least 30 hours; the longest at least 4.1 days. 5 of them had no reported end (still open, or JW's reports stopped), so they count at the length so far. This is a record of the past, not a forecast.
JW's boards first named Lawley Reservoir on 3 March 2025 and last on 29 September 2026: 484 statuses on 484 boards, over 286 days. 178 of those statuses announced a scheduled overnight closure, which we count apart, never as an outage.

Each row is one outage: a stretch of time JW reported Lawley Reservoir at “poor pressure to no water” or “critically low”, newest first. An outage has no reported end when JW's reports stopped before it ended, or when it was still going at JW's last report; its length is then a minimum.

What JW's boards cannot tell you
- 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.
