Error in Reported USGS Discharge at Barton Springs
The reported Barton Springs flow values (here) from the USGS website are not presently accurate due to the Government Shutdown. Small adjustments to the pool level due to pool management affect the nearby USGS gage used to estimate springflow. The USGS makes adjustments to the gage-springflow relationship to compensate for changes in the pool level. However, with staff on furlough, those adjustments are not occurring and so the gage is erroneously reporting some of the lowest values ever recorded (9.9 today, the lowest during 1956 was 9.6 cfs). We know that is not true. Manual measurement this week was about 24 cfs.
