Support the Leaping Lights Festival run by the Severn Rivers Trust by donating via this 'Crowdfunding' campaign.

The Leaping Lights Festival is a beautiful parade of salmon lanterns through the town of Newtown, Powys that celebrates the migration of salmon into local rivers.

Children build lanterns and learn about clean rivers and atists create a spectacle finale. The message is the importance of our ancient relationship with the wildlife of our rivers.

Teaching the next generation about the salmon and how it is called back to the special place it calls home to lay eggs each year will inspire young people to care for rivers.

The Natural Flood Management Project run by Chris Uttley for Stroud District Council is a tremendous example of what can be achieved to reduce flooding and increase biodiversity at low cost by working with a forward thinking landowner and in partnership with local stakeholders.

This video has been produced to show the principles and techniques used in Stroud that mimic the natural environment to slow the flow of water during periods of heavy rainfall. The techniques used in the stream channel will be very familiar to supporters of the WTT – lots of large woody debris!

The video is available on the Stroud Council website

The Irish International Fly Fair takes place at Killyleagh on 2-3 July 2016 – Ireland’s only not for profit International Fly Fair that combines fly fishing with the environment and specifically the trout, sea trout and salmon of Strangford loch and the local rivers.

This year, the Fly Fair is combined with a workshop about the role and formation of Rivers Trusts in Ireland.
The WTT will be represented at the workshop.
Attendance is free but places are limited so you are invited to register in advance.
Click here for details of how to register and the workshop agenda.

The workshop is hosted by the Dibney Rivers Conservation Trust and the Atlantic Salmon Trust.

A landmark report, published 13 May, highlights the work of S&TCUK and Dr. Nick Everall of Aquascience Consultancy Ltd, looking at the diversity and abundance of aquatic invertebrates in 120 sites on 12 English rivers; 14 sites are described as 'pristine'. Phosphate enrichment and sedimentation in combination seem especially problematical. Some iconic rivers such as the Itchen, Lambourn, Test and Wensum, rank “poorly” in the census. Shrimp (Gammarus) numbers were very low across many of the sampled rivers relative to historic, Environment Agency records.

S&TCUK plan further research, including water quality testing to zero-in on the causes of water quality problems. S&TCUK stress that the “…message is that action, not talk, is now urgently needed”.

The full report, Riverfly Census 2015, is available through the S&TCUK website

The Wessex Chalk Streams and Rivers Trust have used the same methdology to anyalse the invertebrate diversity and abundance on the Rivers Itchen and Test in Hampshire. A summary of their findings is available here.

Working with natural processes to reduce flooding (also known as Natural Flood Management or NFM) is receiving a great deal of media and professional attention particularly since the floods in late 2015. The WTT sees this as a very healthy development: working with natural processes rather than dredging and canalising rivers is good for our rivers and wildlife as well as for people and property.

The evidence for the effectiveness of NFM is gradually building and the recent report produced by the Forestry Commission on the impacts of the use of flood storage and ‘leaky dams’ on slowing the flow on the Pickering Beck is a welcome addition. 

The Environment Agency in England has a programme of research and dissemination that aims to 'allow flood and coastal erosion risk management to be carried out sustainably, improving the environment for people and wildlife'.

Alastair Driver of the Environment Agency recently visited Stroud where the local council have carried out a natural flood mnagement project. He says 'the project  is very low cost, the work achieved in a short space of time is remarkable and the results so far are striking' . Click here for a copy of his notes on the visit. 

In Scotland SEPA have produced a very useful handbook which is a practical guide to the delivery of natural flood management.

It is World Fish Migration Day is on Saturday 21 May. Click here to see their newsletter.

The World Fish Migration Day (WFMD) is a one day global-local event to create worldwide awareness on the importance of open rivers and migratory fish. This event is celebrated by over 1000 organizations around the globe (#wfmd2016). 

They have released a couple of short videos:

Following the Salmon Summit in November 2015, a group of partners, headed by the Environment Agency, has launched an initiative to address the demise of salmon and sea trout in England.

The Salmon Five Point Approach – Restoring Salmon in England brings Govt agencies and a host of NGO partners together to implement a series of new measures and invigorate existing ones to maximise smolt production in freshwater and minimise marine mortality. Many of the issues facing salmon also majorly impact sea trout stocks – reduced flow, pollution and barriers in rivers, legal and illegal fishing at sea – so WTT is pleased to offer its full support to the initiative.

A copy of the narrative and high level commitments of the Salmon Five Point Approach is available- click here.

This year’s winners of the prestigious UK River Prize and Nigel Holmes Trophy are the Rivers Eden, Derwent and Kent. The work being carried out across Cumbria is a great example of what can be achieved through working in partnership to achieve multiple benefits such as natural flood management, water quality and biodiversity.

Congratulations to the project partners: Eden Rivers Trust, West Cumbria Rivers Trust, South Cumbria Rivers Trust, Natural England and the Environment Agency.

Fisheries ‘enhancement’ (specifically mitigation stocking) has often been used to offset fisheries or environmental pressures in marine, diadromous, and freshwater fish species, despite relatively scant data to support its efficacy. When considering salmonids, there is a large (and growing) body of literature on experimental studies which points to substantial risks where enhancements are intended to protect, support, restore, or enhance wild fish populations through the introduction of cultured (farmed) or non-native (transferred between systems) fish. We outline some of the problems on our library page on trout stocking, here.

Within the UK, one such long-term, seminal study site is the Girnock Burn, part of an intensively studied research catchment on the Aberdeenshire Dee, in north eastern Scotland. Scientists from Marine Scotland published a paper last year which presents the findings of an experimental conservation stocking programme designed to increase the freshwater production from a declining population of Scottish ‘spring’ Atlantic salmon. The study can be accessed, here.

The stocking programme was in response to a long-term (~30 year) decline in returning female numbers, culminating in three successive years when egg numbers were estimated to be considerably lower than the threshold considered necessary to sustain production. It was designed in line with best practice guidance to maximise egg survival, minimise juvenile competition, and increase overall production. Hence, protocols were developed to:

  1. retain genetic integrity and diversity through the use of indigenous (ie returning) fish and by allowing multiple mating attempts;
  2. minimise overwinter mortality and promote natural rates of embryo development; and
  3. minimise local density-dependent mortality by distributing eggs at uniform densities throughout the catchment.

The Marine Scotland team assessed the relationship between stock (egg deposition) and freshwater production (juvenile emigrants), and determine whether the combination of incubation methods and stocking protocols used in the study resulted in detectable changes in emigrant production relative to natural conditions. They could do this using the wealth of long term data derived from adult and juvenile emigrant data collected over 34 years of natural spawning (1966–1999) in conjunction with 8 years of conservation stocking (2000–2007).

Despite stringent application of all the above, the results indicated that the stocking programme failed to increase salmon production, an important conclusion especially for a river where wild populations remain and where suitable habitat exists.
