GBNI3NB0026 and GBNI1NB030308089 - DWS Impoundment Name/Works Spelga Dam Morphological Impact Yes Impoundment Present Height of Impoundment 30m Compensation Flow Ml/D Yes 2.28 Hydrology Impacted Yes 133 © Crown copyright and database rights OSNI EMOU206.2
Spelga Dam and River Bann At the workshop the main impacts are on the hydrology and morphology of the river downstream. Flow is impacted but the compensation flow is adequate (greater than the Q95 low flow) and therefore this is screened out. Downstream of the impoundment is engineered but not for a significant distance. Mitigation measures to implement sediment management plans and freshets are a possibility but would need taken forward with NIW. Sheep dipping is also present in the area. GBNI3NB0026 - DWS Workshop Classification of reservoir: MEP Chemical status: Good Biological status: Bad 2009 Classification: MEP or worse There was insufficient biological data available to provide a more specific classification. Diatom data was unavailable at the time of classification and UKTAG guidance recommended not using macrophytes or fish for classification as they would be reflecting the hydromorphological pressure that is associated with its use.
