	\|Project summary=The habitat in the Barkston Reach was also poor due to the effects of straightening, dredging and impoundment. Siltation of the over-wide riffles and the lack of cover for juvenile and adult fish were identified as key issues and addressing these was the main focus of the enhancement work.		\|Project summary=The habitat in the Barkston Reach was also poor due to the effects of straightening, dredging and impoundment.

	The enhancement works were planned in two phases and designed by Environment Agency staff in consultation with Grantham Angling Association Fly Fishing Section (GAAFFS) and the riparian landowners.

	The Enhancement Schemes		The Enhancement Schemes

	The principal function of the works is to create sections of 2-stage channel where the river has been widened and deepened. Here a variety of channel narrowing structures have been installed just above the normal water level to create a low flow channel, but are readily over-topped as the water level rises to ensure that the capacity of the channel is not compromised. Techniques include brushwood mattresses and enclosures, log flow deflectors and vanes and tree management.

	\|Monitoring surveys and results=A variety of monitoring techniques have been employed to assess the impacts of the works. These include fixed point photography, along with regular visual inspections to monitor the integrity and performance of the in-stream structures. An annual programme of fine sediment and gravel sampling to monitor changes in the bed substrate has been established and native crayfish surveys will be repeated on a 2 years cycle. Annual fish surveys are already undertaken and show that the brown trout stocks are currently healthy.		\|Monitoring surveys and results=A variety of monitoring techniques have been employed to assess the impacts of the works.
