Alexander Park Reservoir over time

In 2026 so far, JW reported Alexander Park Reservoir short of water on 9 days

What JW reported each day, 3 March 2025 to 29 September 2026, one row a month; the number at the right is the month's days short of water. Based on 281 days with a JW report. 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”. Gaps: Alexander Park Reservoir: no report from 25 July 2025 to 31 January 2026.

From April to September 2026 (six months), JW reported Alexander Park Reservoir short of water on 5 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: 9 days short of water for Alexander Park Reservoir, from 185 days with a report. The median supply in the city: 4 days.

On Alexander Park Reservoir, half of its last 10 outages lasted at least 21 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 Alexander Park 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 (2 of 10).

JW's notices gave 9 end times for Alexander Park Reservoir. By the stated time, JW's boards showed the water back on none of the 9 that have passed

The water came back after the stated time 6 times; half of those times it was back within 6 days of it. For 3 of the 9, JW's boards have not shown the water back since. 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 10 notices.

In words

2026 so far: JW reported it at “poor pressure to no water” or “critically low” on 9 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 15 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 at least 21 hours; the longest at least 3.2 days. 2 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 Alexander Park Reservoir on 3 March 2025 and last on 29 September 2026: 489 statuses on 489 boards, over 281 days. 112 of those statuses announced a scheduled overnight closure, which we count apart, never as an outage.

Days JW reported Alexander Park 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 Alexander Park 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.
