Yorkshire Water, in collaboration with Arup, is investigating compliance of its reservoir assets with the Good Ecological Potential (GEP) objectives of Heavily Modified Water Bodies (HMWBs) under the European Water Framework Directive (WFD). The overall investigation aims to establish the technical feasibility, effectiveness, and cost-benefit of a range of solutions to mitigate the hydromorphological, biological, and water quality impacts of impoundment assets; setting out a framework for their trial, assessment, and optimisation. This includes trialling river restoration actions, as a potential alternative solution to reservoir flow release modifications. The works have been designed to substantiate the evidence base concerning the ecological benefits of various options to address key mitigation measures. To achieve this, each trial is based upon an intensive monitoring programme, tailored around GEP assessment quality elements.
Two pilot river restoration sites have been identified downstream of YW reservoirs. Both sites are subject to low flow impacts, as well as additional pressures relating to sediment regime, physical habitat quality, and water quality.
Fish - research undertaken by HIFI - Electric fishing to estimate fish species composition and population densities. - Scales sampling to determine age and growth of fish populations. - Factors affecting fish population distribution and abundance. - Assessment of recruitment and mortality schedules. - Assessment of habitat characteristics (HABSCORE) including suitability and availability for juvenile trout abundance.
Macroinvertebrates - research undertaken by ECUS - Multi-season macroinvertebrate sampling and identification. - Kick sampling to interpret community assemblages present across variety of habitats. - Habitat-specific sampling to identify species-habitat unit correlations. - Combined with detailed geomorphological mapping to guide habitat restoration design and semi-quantitative analysis of expected change. - Physiochemical variables collected and RIVPACS physical parameter data analysis.
- Qualitative analysis of environmental conditions, drivers and potential controls through standard indices relating to water quality and flow (BMWP, ASPT, LIFE). - WFD classifications derived using RIVPACS methodology and RICT model
Macrophytes - research undertaken by ECUS and Arup - Macrophyte surveys following the EA Macrophyte Survey Methodology (LEAFPACS). - Multiple reach surveys to establish taxa presence and estimate macrophyte and algal percentage cover. - Qualitative analysis of environmental conditions, drivers and potential controls through standard indices relating to water quality and flow (RMNI, RMHI, number of taxa, number of functional groups, percentage cover of algae).
Geomorphology - research undertaken by Arup - Repeat geomorphological site assessments, including detailed mapping of habitat units and geomorphological processes. - Detailed cross-sectional geomorphological analysis, sediment sampling, and flow measurement. - River channel topographical survey. - Repeat photographic and Terrestrial LIDAR surveys.
- Intensive monitoring programmes developed to provide a robust assessment of watercourse status. - Baseline monitoring improving understanding of existing impacts and informing design of bespoke river restoration techniques. - Post-works monitoring to appraise effectiveness of restoration actions in contributing towards GEP. - Extensive monitoring in-line with WFD quality elements: biological indicators, physicochemical parameters, and geomorphological condition. - Methods in-line with EA WFD monitoring and classification procedures, assisting interpretation of change. - Survey sites selected using “Before, After, Control, Impact” (BACI) approach, allowing measurement of restoration impact and comparison of drivers against wider variables.
