On Berea Reservoir, half of its last 10 outages were over within 16 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 Berea 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 (0 of 10).

JW's notices gave 7 end times for Berea Reservoir. By the stated time, JW's boards showed the water back on none of the 7 that have passed
The water came back after the stated time 7 times; half of those times it was back within 52 days 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 8 notices.

In words
2026 so far: JW reported it at “poor pressure to no water” or “critically low” on 16 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 12 days. JW published a report for it on 96 of the 304 days in the record; the other 208 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 16 hours; the longest 3.0 days. This is a record of the past, not a forecast.
JW's boards first named Berea Reservoir on 3 March 2025 and last on 29 September 2026: 490 statuses on 490 boards, over 281 days. 133 of those statuses announced a scheduled overnight closure, which we count apart, never as an outage.

Days JW reported Berea Reservoir at “poor pressure to no water” or “critically low”, out of the days it reported it at all. A month with few reported days says little.

Past outages
Each row is one outage: a stretch of time JW reported Berea 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.
