Flow from Lake Hancock to the Peace River will end this week, Southwest Florida Water Management District officials announced Thursday.
The decision was made the maintain the minimum level in the lake, whose levels were set in 2015 to form a reservoir to help the river meet its minimum flows and levels except during droughts.
Unless more rain occurs, Swiftmud officials predicted some sections of the Upper Peace River will become dry, which was a regular occurrence dating back to at least 1981 before the agency rebuilt the P11 structure on Saddle Creek south of the lake to allow the lake to supplement river flow.
Closing the structure will also allow the lake to retain enough water for now to prevent it from also drying out, which occurred during the drought in 2000.
Swiftmud officials predicted the dropping water flow in the river could eventually result in fish kills because of low oxygen levels in the remaining pools of water.
They also predicted fish kills in the lake as its level drops because of evaporation.
Flow in the Peace River in Polk County has already dropped dramatically in the past week.
At the gauge at State Road 60 in Bartow, flow has dropped from 48.9 cubic feet per second to 20.1 cfs. At Fort Meade flow dropped from 34 cfs to 14.3 cfs.
Farther downstream, flow at Zolfo Springs has dropped from 67.2 cfs early last month to 43.3 cfs Thursday. Flow at Arcadia has dropped from 116 cfs to 74.6 cfs.
The entire Peace River system has been entirely rainfall dependent since artesian flow ceased after Kissengen Spring near the river south of Bartow quit flowing in 1951 because of overpumping of the aquifer by the phosphate industry and sewer discharges into the river and its tributaries from Fort Meade, Bartow, Lakeland and Auburndale were diverted to supply colling water to power plants.
