The system has one first magnitude spring group (>100 cfs discharge) which is the Gainer Springs Group. Four springs or spring groups are currently classified as second magnitude (>10 to 100 cfs). Six springs or spring groups are classed as third magnitude (>1 to 10 cfs). The Barking Spring and Bluff Spring discharge are such that they are considered to be fourth-magnitude (>0.22 to 1 cfs). Discharge measurements collected during the study period are listed in Table_1. Future discharge measurements under other flow conditions may have some effect on the ratings of individual springs.

The point discharge measurements conducted for the Econfina spring inventory are displayed in relation to the quarterly discharge measurements collected for the Gainer Springs Group in Figure 6.

On May 26, 2004 District staff measured a creek flow of 61.4 cfs upstream of Devils Hole near base flow conditions for the study period. The difference between that measurement and the calculated average discharge on May 26 for Econfina Creek at CR388 (450 cfs) is 389 cfs. The total of the ground water discharge measurements performed at springs in the Econfina basin for this study was 320 cfs. Therefore, under base flow conditions, an estimated 82 percent of the Econfina Creek flow between Devils Hole and CR388 originates from springs visited for this inventory. The remaining contribution most likely comes from small surface water drainage systems or other ground water sources such as seep springs, diffuse flow into the creek channel, or other springs not identified under current hydrologic conditions.
