The "Kleinhesseloher See" ("Kleinhesseloher Lake") was created under Werneck's direction around 1800 between the districts of Schwabing, at that time a village north of Munich, and Kleinhesselohe. Kleinhesselohe had been the original northern limit of the park, with a watchhouse and a gate to the northern Hirschau. The park warden there had set up an improvised beer shop for workers in the park. This soon expanded to offer milk and cold meals and came to be a favoured stop for walkers in the park, especially after a wooden dance place had been added. Werneck's successor Sckell increased the size of the lake by one and a half times in 1807 to 1812, giving it its present form. It is constantly fed by water from the Eisbach. Three islands can be found within the lake's 86,410 square meters: "Königsinsel" ("King's Island", 2,720 m2), "Kurfürsteninsel" ("Elector's Island", 1,260 m2) and "Regenteninsel" ("Regent's Island", 640 m2).
