Sheldon Spring is a previously undocumented spring. It is named after a City employee, Henry Sheldon who has been involved with this spring and the sprayfield for a number of years.
There is a low berm around it that was built around the small spring's pool circa 1970 to water livestock. A culvert was located at the east end of the pool. At that time the natural flow was to the north and into the swamp.
When the City of Leesburg purchased the property around 1980 for use as a municipal sprayfield, the outlet was moved to a 24-inch culvert at the northwest corner of the pool. The shallow run now flows to the north-northwest. The run crosses into Sumter Co. about 100 feet north of the outlet and then into the Okahumpka Swamp.
Henry Sheldon reports that the boil is located on the east side of the spring pool. There is a visible opening and it is 6 to 8 feet deep. He further reports that during high flow periods the boil is readily apparent at the surface. When people are swimming in the spring the bottom sediment tends to be stirred up and the water becomes cloudy.
There was an archeology dig conducted by the state near the big oak tree just west of the spring when the City bought the property. They investigated an Indian mound located just over the county line. The mound was named after Charles Bowman who also was a city employee. Artifacts (pottery, etc.) from this dig are on display at the Leesburg's WWTP.
When visited in March 2009 the spring pool was complete covered with duckweed and no boil was visible.
The spring is on restricted access land and is not open to the public. In the past the water had been used to water stock but currently it is unused. The water flows into the Okahumpka Swamp. It is not known if this portion of the swamp either flows east into Lake Denham or to the west and eventually into the gulf.
The spring is located on City of Leesburg property. Because this site is used as a municipal wastewater sprayfield, access is restricted. Permission to visit must be obtained from the City's waste water plant in Leesburg.
