Barton Springs: ~40 cfs (41.7 10-day average)
Lovelady: 481.4 ft-msl (172.0 ft depth to water)
Barton Springs discharge that is reported on the USGS website has been corrected to reflect manual verification measurements. The website was reporting values about 4 cfs too low. District staff also measured springflow and verified the higher values. As such, we've avoided entry into drought for at least a couple of weeks--and hopefully we'll get some rainfall in the meantime.
Unfortunately, the El Nino conditions are very weak, if present at all, so future rainfall projections due to ENSO are not a source of optimism at this time.
Although the District is currently no under drought restrictions or declarations, here's what is happening around us:
Edwards Aquifer Authority:
o Under Stage 2 restrictions (30% curtailment) based on 10-day average values for J-17 (current reading: 648msl; Stage II threshold 650msl, Stage III threshold 640msl).

o EAA Critical Stage Info (Triggers, Stages and Reductions)
City of Austin:

o When lakes reach 900,000 million acre feet, firm water customers required to reduce water use by 10-20%, and they start a curtailment of interruptible supply and environmental flows for critical needs continues.
