Oberstockensee is a small lake in the Canton of Bern , Switzerland . Its surface area is 11.8 ha (29 acres). The lake is located above the village of Erlenbach im Simmental , below Stockhorn . During the 19th and 20th centuries, the "Oberstockensee" was often called the Vorderstockensee and/or Spetbaerglisee. Local residents still refer to it as the "Spetbaerglisee."

Stockhorn: • Johann Gottfried Batzli (1830-1869), the president of the Erlenbach im Simmental Community Council, who only shortly before had been the miller and baker at the lower mill on the "Wildenbach" creek in the village and was long remembered because of his winning personality and his friendly, gentle voice • Johannes Batzli (1862-1869), the seven-year-old orphaned son of a first cousin of the community council president • Rudolf Jutzeler (1853-1869), a sixteen-year-old godson of Susanna Katharina Buehler Zurbruegg (1800-1859), the mother-in-law of Johann Gottfried Batzli • David Sulzener Jr.
