	\|Project summary=The Eefse Beek water body is classified as a river under the WFD system. It is an R5 category water body: slow-flowing middle/lower reach on sand. The entire Eefse Beek is managed by water authority Rijn en IJssel. The water body is located in the province of Gelderland, municipality Lochem. It is 12,1 km long and has a catchment of 4080 hectares. The water body is composed of the Eefse Beek and its tributaries, the Molenbeek and Huurnerbeek. The water body originates in its own catchment and discharges into the river IJssel via the Twentekanaal. Water levels in the Eefse Beek are managed with three adjustable weirs. None of these weirs are passable for fish. In the Eefse Beek water body, a single water level is pursued for each managed stretch. The Eefse Beek carries water all year, with an occasional dry period in summer. There are no sewage treatment plants present in its catchment.		\|Project summary=The Eefse Beek water body is classified as a river under the WFD system.

			Water authority performed several field tests with main channel mowing. The purpose of these tests was to create a validation data set with which the minimum required width of the mowed main channel could be tested. To this end, a different width was mowed in each test.
			\|Monitoring surveys and results=When the cleared channel portion is widened from 2m to 4m, this results in a significant change in surface water level slope. A widening from 4m to 6m does not have such an effect. The portion of the river in which the water can flow freely can be reduced significantly reduced when sediment builds up on the edges of the channel.
