REMARKS.--Computed discharge at this station may differ from individual measurements because of changes in tidal influence, wind, or other factors. At stages below 9.00 ft discharge computed from relation between artesian pressure at Blue Springs well near Madison, FL (302847083145401), provided by Suwannee River Water Management District. At stages above 9.00 ft a differential head rating is used, using Blue Springs well near Madison, FL (302847083145401) and the stage at the site. During periods of high water, the spring is affected by variable backwater from the Withlacoochee River, which at times, can result in negative flow back into the spring vent. Prior to Oct. 7, 2011, discharge was computed using different methods.
