JW's notices gave 3 end times for Robertville 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 66 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 6 notices.

In words

2026 so far: JW reported it at “poor pressure to no water” or “critically low” on 0 days. JW published a report for it on 189 of the 272 days in the record; the other 83 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 0 days. JW published a report for it on 36 of the 304 days in the record; the other 268 days have no report, and we do not count them as normal. The median supply in the city had 1 such day.

JW's boards first named Robertville Reservoir on 3 June 2025 and last on 29 September 2026: 394 statuses on 394 boards, over 225 days. 30 of those statuses announced a scheduled overnight closure, which we count apart, never as an outage.

Month by month

Days JW reported Robertville 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 Robertville 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.

JW reported no such outage for this supply.
