Parts of the Upper Peace River could turn into exposed riverbed within days, as regional water managers prepare to shut a key control gate on Lake Hancock in a last-ditch effort to keep the lake from dropping below its legally required level.
District Orders Closure To Protect Lake Hancock
The Southwest Florida Water Management District says it will close the Lake Hancock P-11 water-control structure this week to protect minimum lake levels. That move will cut off releases to the Upper Peace River, and without those discharges, stretches of the river between Lake Hancock and Fort Meade are expected to go dry and become non-navigable within days. Officials warn that trapped fish and worsening water quality are likely as isolated pools lose dissolved oxygen.
In a news release, the district said staff will slowly close the P-11 structure and that discharges to the river are expected to reach zero by this weekend. The agency added it has "no other options" and that the river may remain dry until the summer rainy season kicks in around June, according to the Southwest Florida Water Management District. The district reports a 12.8-inch regional rainfall deficit compared with the average 12-month total, and notes that below-average rainfall last summer left less water available for dry-season releases.
Water managers say the shortage is already straining regional supplies. As reported by WWSB/MySuncoast, the Peace River Manasota Regional Water Supply Authority told reporters in early March that its reservoir was roughly half full and that the area faced about a 13-inch deficit, prompting conservation measures and operational adjustments.
The dry spell fits a broader pattern across Florida this spring. The U.S. Drought Monitor shows significant drought coverage in the state, and regional hydrology bulletins note falling aquifer and lake levels that limit water managers' options for maintaining river flows.
How Lake Hancock Helped, And Why It Cannot This Time
Lake Hancock has been the Upper Peace River's backup plan during dry months ever since the Lake Hancock Lake Level Modification Project raised the P-11 control elevation to store more water for release. The project description explains that the modification, completed in 2013, was designed to increase storage so the district could release flows during drought. Sustained below-average rainfall, however, has left the lake unable to spare additional water without violating minimum lake levels. A project summary from the Southwest Florida Water Management District lays out how P-11 is used to manage storage and releases.
Local Impacts: Boating, Wildlife And Water Quality
Boaters and paddlers should expect stretches that are normally navigable to turn into shallow runs or exposed riverbed, and residents along the river may see algal mats, odors and dead fish as isolated pools deteriorate. The district has warned that fish kills are likely both downstream of the P-11 structure and inside Lake Hancock as dissolved oxygen drops and temperatures rise. County and state officials typically monitor and respond to large fish-kill events, and the public is asked to report significant wildlife mortality to local agencies.
District staff frame the closure as a temporary, protective action that will be reversed if meaningful rain returns, but they stress that the only real remedy is sustained, significant rainfall. In the meantime, the agency continues to urge residents and utilities to follow existing watering restrictions and conservation guidance while it monitors conditions.
With Florida's main rainy season still weeks away, water managers say rivers and reservoirs remain vulnerable when seasonal dry spells drag on. Readers can follow the district's newsroom and the U.S. Drought Monitor for updates on flows, restrictions and forecasts.
