Armagh. It is a slow flowing, low energy river within an agricultural catchment. The river had been subject to an arterial drainage scheme in the 1960s, which deepened and widened the river as well as disconnecting it from its floodplain. The 1.2km Tall River scheme was the first project within Northern Ireland to address the specific need to enhance the riverine environment, rather than being attached to a larger flood prevention scheme. Works could only be carried out in-channel and on the National Trust owned right bank due to landowner restrictions. The aim of the protect was to create shallow slack-water habitat through the creation of bays. These would provide shelter for fish fry and invertebrates during high flows and aimed to increase macrophyte diversity within the reach. Stone cascades were also installed to direct flow away from potentially erodable banks. A repeat RCS carried out two years post works indicated an increase in emergent vegetation and macrophyte diversity. The bays are inundated at high flows, acting as a fish refuge, however due to siltation these may be becoming too shallow. Following the creation of stone cascades greater flow variation has been ovserved. The success of the bays appears to depend on the presence, or otherwise, of a structure deflecting water into them. If the project was to be carried out again more consideration should be given to the location of the bays within the overall flow regime or alternatively structures that would maintain flows into the bay should be included in the design. Plus, part of a wider scheme developing footpath access along the river.
