Assessment Purpose

This assessment has been produced as part of the national characterisation programme undertaken for the second cycle of Water Framework Directive river basin management planning. It has been led by the EPA, with input from Local Authorities and other public bodies, and with support from RPS consultants.

The characterisation assessments are automatically generated from the information stored in the WFD Application. They are based on information available to the end of 2015 but may be subject to change until the final 2018-21 river basin management plan is published. Users should ensure that they have the most up to date information by downloading the latest assessment before use.

2 Evaluation of PrioritySubcatchment Issues

Two water bodies in this subcatchment are At Risk: Bonet_020 and Shanvaus_010. Both are at Good ecological status overall for 2010-2015 however both have High Status Objectives and so this represents a deterioration in status from 2007-2010. For the Bonet_020, sediment pressures from agriculture and road run-off are likely driving the deterioration from High to Good status (invertebrates are driving the biology). For the Shanvaus_010, the biology status was High (invertebrates) however the water body failed the hydromorphology element of ecological status due to historic channelisation and reduction of riparian buffer. Further characterisation will focus on hydromorphology pressures.

Nutrient concentrations appear relatively low in Glenade Lake, however the invasive zebra mussel has been recorded in the lake. Fish status is the element driving Poor 2010-2015 ecological status. The lake is therefore under Review, pending a review to be carried out on the classification of risk status based on fish.
