Comal Springs’ reported 10-day average flow was 154 cubic feet per second on Oct. 20, down from 155 a day earlier.
The Edwards Aquifer Authority’s daily conditions also put the J-17 well’s 10-day average at 640.1 feet, a decline of 0.2 foot from the previous report. Both changes were small in this one-day comparison.
Residents tracking local water conditions saw a small change in springs flow while Canyon Lake held at 97% of conservation storage. The state’s reservoir figure was unchanged from Oct. 19; the Army Corps of Engineers reported a separate late-evening lake elevation of 907.57 feet on Oct. 20.
Edwards Aquifer and Comal Springs
The Oct. 19 report put J-17’s 10-day average at 640.3 feet and Comal Springs’ 10-day average flow at 155 cubic feet per second. These are reported 10-day averages, so their movement describes a change in the rolling measures, not a one-day measurement of how much water passed through the springs.
For the San Antonio Pool, the Edwards Aquifer Authority listed Stage 2 and a 30% reduction on both dates. That is the authority’s aquifer management designation. Customers seeking a watering schedule or other service rules should consult their own water provider’s current notices; the pool designation alone is not a provider-specific instruction.
