It will be the river with its high flows that finally does the restoration work. The river mobilizes the sediments naturally the year after the removal 42.73695,-5.6446183 Rincón Sanz Duero River Basin District Gonzalo capture of fish prior to the works 22.5 10 - 100 m³/s Dam removal, Reconnection of river,, ,capture of fish prior to the works,, The information regarding the monitoring of La Gotera dam removal is very scarce. A study was carried out prior to the demolition of the dam and another one a year later. Three points were sampled: a reference point upstream the dam, other near the dam wall and a third one downstream the dam. The fish samplings yielded no significant results. However, all macroinvertebrate indices did show an improvement, especially in the sampling point downstream of the dam. 23397 Image of the removal works of La Gotera dam.

The slope between the river and the banks required the construction of a ramp so that the machines could access to the river. Due to the impossibility of removing the material from the ramp once the work was finished, material from other restoration activities in other river reaches was used. The native vegetation of the area was respected during the works of removal. In addition, it will serve to fix the ramp that allows the approach of the machines to the river. Prior to the removal, a capture of the fish specimens located upstream of the dam was performed and subsequently released in the same river away from the intervention. A high abundance of fish was observed. A volume of 1,068 m3 of debris was removed during the works. The concrete from the bypass channel and the dam was removed in the last phase of the work. All elements that are strange to the river like the concrete or metallic remains were removed from the river and moved to authorized dump sites. With this removal, 15 kilometers of river that previously were interrupted by the dam has been reconnected. Barely a month after the removal of the obstacle, the river has recovered its natural course La Gotera dam removal la gotera dam removal No References Headwaters Economics (2016).
