Question: Middle Lake Hamilton, is a natural freshwater lake on the northeast edge of a Florida city located in what county?
Context: Clear Lake is a natural freshwater lake located in Lake County in the U.S. state of California, north of Napa County and San Francisco.  It is the largest natural freshwater lake wholly within the state, with 68 mi2 of surface area.  Lakes have existed at the site for at least 2,500,000 years, possibly making it the oldest lake in North America. Bear Lake is a natural freshwater lake on the Utah-Idaho border in the Western United States.  About 109 sqmi in size, it is split about equally between the two states; its Utah portion comprises the second-largest natural freshwater lake in Utah, after Utah Lake.  The lake has been called the "Caribbean of the Rockies" for its unique turquoise-blue color, which is due to the reflection of calcium carbonate (limestone) deposits suspended in the lake.  Its water properties have led to the evolution of several unique species of fauna that occur only within the lake.  Bear Lake is over 250,000 years old.  It was formed by fault subsidence that continues today, slowly deepening the lake along the eastern side. Winter Haven is a city in Polk County, Florida, United States.  The population was 33,874 at the 2010 census.  According to the U.S. Census Bureau's 2015 estimates, the city had a population of 37,689, making it the second most populated city in Polk County.  It is a principal city of the Lakeland-Winter Haven, Florida Metropolitan Statistical Area. Lake Okeechobee ( ), also known as Florida's Inland Sea, is the largest freshwater lake in the state of Florida.  It is the eighth largest natural freshwater lake in the United States and the second largest natural freshwater lake (the largest being Lake Michigan) contained entirely within the contiguous 48 states.  Okeechobee covers 730 sqmi , approximately half the size of the state of Rhode Island, and is exceptionally shallow for a lake of its size, with an average depth of only 9 ft .  The lake is divided between Glades, Okeechobee, Martin, Palm Beach, and Hendry counties.  All five counties meet at one point near the center of the lake. Middle Lake Trail is in the northwestern Sawatch Range, part of the Rocky Mountains in the U.S. state of Colorado.  It is located in the Holy Cross Wilderness northeast of New York Mountain in Eagle County.  Middle Lake Trail is south of Interstate 70, near Eagle and Edwards.  Middle Lake Trail is accessible by hiking south along the Dead Dog Trail from West Lake Creek Road south of Edwards.  Dead Dog Trail crosses a ridge and ascends to a junction with the Middle Lake Trail that is 3.3 miles from Dead Dog trailhead, at 11,250 feet.  Middle Lake Trail continues east to the top of the ridge, at 11,770 feet, overlooking East Lake Creek Valley.  Then, Middle Lake Trail drops off the ridge to Middle Lake.  Hiking Colorado: Holy Cross Wilderness, a hiking guide by Kim Fenske, provides a description of Middle Lake Trail access from Dead Dog Trail. The Chain of Lakes are a famous series of lakes in Central Florida.  There are two chains of lakes, the northern chain and the southern chain.  The northern chain extends across three cities; Winter Haven, Lake Alfred, and Lake Hamilton.  It has ten lakes, connected by a series of canals.  The ten lakes on the northern chain are: Lake Haines, Lake Rochelle, Lake Echo, Lake Conine, Lake Fannie, Lake Smart, Lake Henry, Lake Hamilton, Middle Lake Hamilton, and Little Lake Hamilton. Lake Angelo is a round natural freshwater lake in Highlands County, Florida, located 0.5 mi east of Avon Park, Florida.  Lake Angelo has a surface area of 55.73 acre .  On the south the lake is bounded by woods and grassland.  Angelo Lake Road starts beyond the woods at State Highway 17 and travels almost halfway around the lake, taking off to the north at the lake's northeast edge.  Sears Road is on the north and Lake Angelo Drive is on the west.  Houses and private boat docks line the lake along these two roads. Little Lake Hamilton has a surface area of 367 acre .  Little Lake Hamilton is bordered by Haines City, Florida, on its north side and is almost bordered by the town of Lake Hamilton, Florida, on its south side.  This lake is in places bordered by residences and in other places is bordered by woods and pastureland.  It is east of Middle Lake Hamilton and is ironically much larger than that lake. Middle Lake Hamilton, is a natural freshwater lake on the northeast edge of Winter Haven, Florida.  At one point on the north shore the Winter Haven city limits touches the lake's shore.  This lake has an 103 acre surface area.  Middle Lake Hamilton is between two other lakes with Hamilton in their names, Lake Hamilton (Florida) and Little Lake Hamilton.  Ironically, Middle Lake Hamilton is considerably smaller than Little Lake Hamilton.  Much of Middle Lake Hamilton's north and northwest shore is bordered by a residential area, which is partly inside Winter Haven.  The northeast shore is bordered by woods.  The entire shore from the southeast around to the southwest is bordered by the Lake Region Mobile Home Park. Lake Hamilton is somewhat round with a large cove at its northwest edge.  It also has a peninsula, sometimes called Bonars Island, on its north side that juts about 2,000 ft south into the lake.  During times of high water levels this peninsula becomes a large island.  Lake Hamilton has a surface area of 2,184 acre .  One large island is in the south-central part of the lake; it measures 1,410 ft long by 1,060 ft wide.  Another large island is near the northeast shore of Lake Hamilton; it measures 825 ft long by 470 ft wide.  At least two small islands are also within Lake Hamilton.
