Project summary
Section of the Ouzel in Milton Keynes. The river has modified in the past, for example, channelization works have created a more uniform channel cutting off meanders and reducing hydromorphological diversity in flow and channel bed forms.
Works over an 80m section included 3 single and 1 paired deflector. The aim of these works was to increase diversity of flows and bed profile over this section. It is anticipated that over time, underlying gravels, currently overlaid by fine sediment will be kicked up by localised scour (from deflectors) and also improve habitat quality for invertebrates and for fish spawning.
Monitoring surveys and results
- Pre-enhancement fish survey undertaken.
- Post-enhancement surveys planned.
- River habitat assessment survey (Central Habitat Assessment)
