The Tyne Rivers Trust will be £250,000 better off following a decision by the Court of Appeal earlier this week allowing construction of a second Tyne Tunnel.
Green campaigner Brian Atkinson was told on Wednesday that he could not appeal against a High Court decision backing the building of the river crossing between North and South Tyneside, which he said was a "disaster for Jarrow".
Now the plans for the £185m link have been given the go ahead it will release funding of £250,000 to the Trust, based in Hexham, Northumberland, from the Tyne and Wear Passenger Transport Authority (TWPTA). This will be used to introduce a number of improvement schemes on the river to prevent any environmental impact the construction work will cause.
The projects include improvements to habitats to promote the health of the river, and the construction of a new fish pass at Hexham to allow salmon, sea trout and eels better access to their spawning grounds on the upper reaches of the North and South Tyne.
The trust is also hoping to introduce other catchment projects in the future if funding is made available.
Trust chairman Andrew Davison said: "We were fully consulted during the preparation of the new tunnel plans and now look forward to continuing to work closely with TWPTA.
"Associated with the new tunnel were agreed safeguards that will minimise the impact on the quality of the water in the Tyne during the construction.
"The decision means that we can now prepare to deliver the projects that the TWPTA will fund to help secure the health of the river for generations to come.
"We have completed an extensive public consultation process to identify key projects and will be launching the first ever Strategic Action Plan for the Tyne Catchment in September."
The Tyne Rivers Trust will launch the Strategic Action Plan for the Tyne Catchment at Hexham Racecourse on September 11. Work that the trust is looking to do in the future includes setting up River Watch - a network of volunteers to help monitor and manage the catchment and a Wild Angling Passport Scheme.
