From April to September 2026 (six months), JW reported Yeoville Reservoir short of water on 11 of 159 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: 11 days short of water for Yeoville Reservoir, from 185 days with a report. The median supply in the city: 4 days.

On Yeoville Reservoir, half of its last 9 outages lasted at least 36 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 9 outages on Yeoville 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 (1 of 9).

JW's notices gave 26 end times for Yeoville Reservoir. By the stated time, JW's boards showed the water back on none of the 24 that have passed

The water came back after the stated time 24 times; half of those times it was back within 1 day 11 hours 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 28 notices.

In words

2026 so far: JW reported it at “poor pressure to no water” or “critically low” on 11 days. JW published a report for it on 185 of the 272 days in the record; the other 87 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 6 days. JW published a report for it on 87 of the 304 days in the record; the other 217 days have no report, and we do not count them as normal. The median supply in the city had 1 such day.

The last 9 outages JW reported on this supply lasted a median of at least 36 hours; the longest at least 2.8 days. 1 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 Yeoville Reservoir on 3 March 2025 and last on 29 September 2026: 465 statuses on 465 boards, over 272 days. 3 of those statuses announced a scheduled overnight closure, which we count apart, never as an outage.

Past outages

Each row is one outage: a stretch of time JW reported Yeoville 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.
