Options report on the current situation at Emyvale weir with a view to altering a proportion of river flow to favour the Mountain Water main channel downstream of Emyvale weir.
Under the current situation, the weir is in use to divert water to Emy Lough. The diverted water does not return to the Mountain Water from Emy Lough but rather flows directly into the Ulster Blackwater river.
This diversion creates a significant impact on hydromorphological conditions downstream as there are insufficient water volumes to sustain natural environmental regimes
