The Welland is some 65miles (105 km) long.It rises at Sibbertoft, a village west of Market Harborough, then flows eastwards through that town, creating a broad, flat valley before entering Stamford and from there the fens. It flows through Spalding as a tidal river that joins the Wash Estuary at Fosdyke.

The tributaries which flow into the Welland are:Eye Brook:TheRiver Chater:TheRiver Gwash:TheRiver Glen:TheRiver Jordan, Northamptonshire:Vernatt’s Drain

[toggle title=”Where does the Welland get its water from?”]

It collects water along its course from tributaries flowing from the North, but very little from the south. The most important of these are the Gwash, which holds Rutland Water and the Glen draining south-west Lincolnshire.

[toggle title=”What is a Fish Refuge?”]

A fish refuge is a pond off the main river with one entrance, so that it is away from the flow of the river and offers fish shelter in times of flood. When told of the project, people often ask, ‘How will the fish know where it is?’ The answer is quite simple, just as you and I know where the lay-bys, the pubs and other features are in our districts, so the fish know where to hide in difficult times in their area.

Eutrophicationis an increase in theconcentrationof chemicalnutrientsin anecosystemto an extent that increases theprimary productivityof the ecosystem. It is similar tored tides, depending on the degree of eutrophication. Similarities include subsequent negative environmental effects such as anoxia and severe reductions in water quality, fish, and other animal populations may occur.

Water abstraction,water extraction, orgroundwater abstractionis the process of takingwaterfrom any source, either temporarily or permanently. Most water is used forirrigationor treatment to producedrinking water.

Depending on the environmental legislation in the relevant country, controls may be placed on abstraction to limit the amount of water that can be removed. Over abstraction can lead toriversdrying up or the level ofgroundwateraquifersreducing unacceptably.

The science ofhydrogeologyis used to assess safe abstraction levels.
