Estenstadmarka is a hilly, wooded area east-southeast of the city center of Trondheim, in Trøndelag county, Norway. It is mainly used for recreation by the people of Trondheim. There are several gravel roads and, during the winter season, electrically lit cross-country skiing trails. There are also several lakes and a cabin (Estenstadhytta, 329 m above sea level). From the Månen viewpoint, there is a beautiful view over the city and the fjord.
Estenstad Dam is a popular tourist destination in Estenstadmarka. Nestled amidst hilly terrain with abundant coniferous forest, open cultivated landscapes, and water provide a welcome change of scenery.
At the beginning of this century, Strinda had no water supply other than agricultural wells. In 1908, a proposal was made to the Strinda Presidency to establish Estenstad Dam as a water supply point for Strinda Municipality.
In 1910, Estenstad was purchased. By 1912, the waterworks employed 20-40 construction workers, and the following year, it was operational. However, it soon became apparent that the water quality had deteriorated somewhat due to storage in the reservoir. The water was browned by the bog ore and the peat layer at the bottom. Many proposals were made and tests were conducted, but the water did not become any cleaner. In 1921, it was decided to remove the bog down to the sandy and clay soil. 50,000 m3 of material had to be removed. When the work was completed in 1924, the water quality was excellent. However, the demand for water grew rapidly. A dam filled with brown, useless water was built at Tømmerholt in 1912-13. The city engineer suggested that the bog masses in this pond should also be removed. 100,000 m3 had to be removed. When this work was completed in 1933, the basins held 375,000 m3. The place where the bog masses ended up was called Myrtippen. In 1964, the joint waterworks for Trondheim and Strinda was completed. But it would be another 33 years before Estenstaddammen was closed as a water reservoir and Jonsvatnet took over completely. The highest settlement received water from Estenstadmarka until 1997. Previously, fishing was prohibited in both the Tømmerholt Dam and the Estenstad Dam due to drinking water restrictions, but these were lifted in 2004.
