Nissum Fjord

Nissum Fjord is an approximately 70 km2 coastal lagoon on the West Coast, approximately 20 km south of Lemvig. Nissum Fjord is separated from the North Sea by a isthmus, where the town of Thorsminde is located. The Storåen and several smaller streams flow into Nissum Fjord. At Thorsminde there is a lock that regulates the water level and salinity in the fjord. Nissum Fjord is a brackish water lake, and has an average water depth of 1 m and is only 2.5 m deep at its deepest points. It can be divided into three basins, which are separated by sills with shallow water depth, Yderfjord, Mellemfjord and Felsted Kog (see map).

Along Nissum Fjord there are a number of diverse landscapes that suggest the area's complex geological history. To the east the fjord borders Kronhede-

Klosterhede meltwater plain. Storåen , which has its outlet in Felsted Kog, runs in the southern part of the meltwater plain. The river has changed course several times, and has flowed both north and south of its current location. Storåen's delta has grown considerably westward in historical times. Along the southern shore of Nissum Fjord there are some low hill sections, which are offshoots of Skovbjerg Bakkeø. To the west, Nissum Fjord is bordered by the aforementioned spit, which consists of marine foreland and dunes. See the Nissum Fjord Nature Park website
