Where does the Welland start and finish?

The Welland is some 65 miles (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: The River Chater: The River Gwash: The River Glen: The River Jordan, Northamptonshire: Vernatt's Drain.




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.


Can I volunteer to help?

Yes. The Trust always welcomes volunteers who can give time to helping with our various projects and activities. You don't have to have any specialist knowledge, although if you do have a relevant skill or interest, let us know.

You can register your interest by completing our Volunteering form here. We will then add you to our register and keep you updated with events and projects which may be of interest.


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.


What is Eutrophication?

Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases the primary productivity of the ecosystem. It is similar to red 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.


What is a Riffle?


A stream riffle (also known as a swift) is a shallow stretch of a river or stream, where the current is above the average stream velocity and where the water forms small rippled waves as a result.

It often consists of a rocky bed of gravel or other small stones. This portion of a stream is important habitat for small aquatic biota (invertebrates and juvenile fish--fries).


What is Abstraction?


Water abstraction, water extraction, or groundwater abstraction is the process of taking water from any source, either temporarily or permanently. Most water is used for irrigation or treatment to produce drinking 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 to rivers drying up or the level ofgroundwater aquifers reducing unacceptably.

The science of hydrogeology is used to assess safe abstraction levels.
