Lake Limestone is a 13,680 acres (55.4 km 2) reservoir near Thornton, Texas. It lies 15 miles (24 km) southeast of Groesbeck, Texas on Texas FM 3371 in Leon , Robertson and Limestone Counties. The lake's water is slightly alkaline, moderately clear, with a maximum of 42 feet (13 m) deep.
The name comes from the Irish tur, meaning "dry", and loch, meaning "lake". The water bodies fill and empty with the changes in the level of the water table, usually being very low or empty during summer and autumn and full in the winter. As groundwater levels drop the water drains away underground through cracks in the karstic limestone. [2]
The main factors affecting sea level are the amount and volume of available water and the shape and volume of the ocean basins. The primary influences on water volume are the temperature of the seawater, which affects density , and the amounts of water retained in other reservoirs like rivers, aquifers, lakes , glaciers, polar ice caps and sea ...
Members of the Local Environmental Action Demanded (LEAD) Agency, an area advocacy group, worry that raising the water level will make flooding worse at the lake's upstream rivers.
Castle Rock, which rises 195.8 feet (59 m) over the waters of nearby Lake Huron, was created by erosion of surrounding land. After the Wisconsinan Glaciation, post-glacial Lake Algonquin formed. The Ice Age melt off caused the waters of Lake Algonquin to be much higher than the water level of Lake Huron is today. Over time, the declining water ...

The limestone protects the lake from the damaging effects of acid rain. [2] There are various features surrounding the lake that are evidence of the glacier. These include moraines, drumlins, hanging deltas, clays and sands. There is also evidence that shows a previously higher lake level had existed, known as "Lake Cooperstown".
The lake drained about 13,000 YBP, until reaching the level of the Momence Ledge. The outcropping of limestone created an artificial base level, holding water throughout the upper basin, creating the Grand Kankakee Marsh. Lake Kankakee was a prehistoric lake during the Wisconsin glacial epoch of the Pleistocene Era.
