Weirs and structures on the River Teme are generally linked with negative impacts on the physical and ecological condition of the river. Firstly, structures can significantly alter the depth of water and velocity of flow, leading to over deepened impounded reaches upstream and altering the habitat characteristics. Secondly, structures affect the rivers ability to transport sediment downstream, again altering habitat characteristics. Finally, structures in the channel impact upon the biological connectivity of the river, preventing fish and invertebrate passage.

There are large numbers of existing weirs that have been erected for various water uses in the recent past. This has a significant impact on in-channel sediment continuity, hydromorphic biotope diversity and fine sediment deposition on the channel bed upstream of the structures within the impoundment zone. However, it is acknowledged that some weirs have significant historic interest. There are numerous opportunities for weir removal, alongside morphological enhancement of the watercourse, to improve sediment continuity, restoring a more natural functioning hydromorphology and improving fish passage.

A number of barriers (weirs) have been removed along the River Teme, however seventeen remain which could present a barrier to fish movement. Since 2012 we have been undertaking feasibility studies and modelling to determine the most efficient, cost effective and aesthetically suitable method for removing some of these barriers. Please see the Publications pages for copies of reports.
