Edward Medard Reservoir, Plant City: The Mine That Became the Park
The 770-acre lake east of Brandon where a quarter-million people a year come to fish and camp was, in the 1960s, an open phosphate pit
The 770-acre lake east of Brandon started as a hole. Draglines worked the ground here in the 1960s, stripping phosphate out of the earth on Turkey Creek Road south of Plant City. What they left was the shape of any worked-out mine — a pit, spoil banks, exposed ground. In 1970 the pit was impounded, water was allowed to fill it, and the flooded mine became a reservoir. Two years later, under agreement with the water management district, Hillsborough County developed the site into one of its largest regional parks. Today it draws about 250,000 visitors a year.
That number is the story. A quarter of a million people come each year to a body of water that exists because a mining pit was flooded on purpose.
Central Florida runs on phosphate. Polk and Hillsborough counties sit over some of the richest deposits in the country, and mining left thousands of acres of altered ground across the region — pits, settling ponds, spoil piles. Some of it stayed scarred for decades. The site that became Edward Medard Reservoir took a different path: mined in the 1960s, diked in 1970, opened as a park two years after that. The turnaround from active mine to public reservoir was fast by any measure.
The reservoir carried an earlier name — Pleasant Grove Reservoir — and the park did too, before both were renamed for Edward Medard. The dam that holds the water back is an earthen structure at Pleasant Grove. It's the reason the lake exists as a lake and not a slow-draining pit. Everything downstream of that dike — the fishing, the boating, the 250,000 annual visits — depends on 1970's decision to hold the water in place.
The pit filled, and the fish came. Largemouth bass, bluegill, catfish, and crappie now make up the bulk of what anglers pull out of it. A flooded mine, given enough time and water, becomes a warm shallow lake indistinguishable from the natural ones around it — the same species, the same seasonal patterns. The origin doesn't show in the fishing report.
What the county built around the water reads like any large regional park: a 700-acre reservoir open to boating and fishing, camping, disc golf, equestrian trails. The park runs on seasonal hours — 8 a.m. to 6 p.m. in fall and winter. None of it hints at the mining. The spoil banks that a dragline left became the high ground trails run across. The pit became the lake people put boats on.
The site sits in a stretch of Hillsborough County where the exact geography gets described differently depending on who's writing it down. FWC puts it six miles east of Brandon, one mile south of State Route 60 on Turkey Creek Road. Other sources place it south of Plant City, or just north of Durant. They're all describing the same park — a large piece of ground in eastern Hillsborough County, big enough that where you enter it changes which town you'd say it's near. One county source puts the full park at 1,284 acres, nearly double the reservoir itself, which fits a park that carries trails, campsites, and a disc golf course alongside the water.
The land was mined for what could be taken out of it and then handed off. What went in afterward — the dike, the water, the fish, the trails — turned a subtraction into something a quarter-million people choose to visit each year. The dam at Pleasant Grove still holds, and the water behind it still fills a shape that a dragline dug more than sixty years ago.
