The grassland has a variety of flowers, which support a variety of insects, birds and mammals. The visitor centre opened to the public in 2010. During the late 20th century College Lake was a working quarry and the chalk was excavated and made into cement for use in building construction. Many fossils, including ammonites and sea urchins, were uncovered during the excavations and fossils from the site are on display in the visitor centre . There is access from the Upper Icknield Way. The site takes its name from College farm that existed here before quarrying started in the twentieth century. The farm buildings were located on the rising ground on the north side of the present lake. The farm in turn took its name from Trinity College Cambridge which owned the land.Information provided in Visitor Centre March 2023.
