River and Glenquey update July 2016

Apologies for the lack of news in recent months, in part driven by other commitments but certainly from my perspective the first months of the season on river to mid June were really slow.

River Devon

The river has been uniformly low for much of May and June, the only saving grace being the occasional additional release from Castlehill Reservoir when they have been running their hydro-electric plant. These general raise the level of the river by 10-15cm for a couple of days and does help clear some of the silt/algae that forms in the prolong dry spells.

In the early season there were a couple of reports of decent fish being caught by bait anglers of up to 4lb. It is only in recent weeks with a bit more cloud cover and rain things have improved. I finally began rising and catching decent trout with the dry flies (including a cracker of about 2.5lb. There have even been reports of Sea Trout splashing in pools …….. the sceptics find this surprising considering how low the river has been

Annual stocking has been completed: these fish have now moved away from where they were released and can still be found. One angler recently caught nine stocked fish in one session (all released).

Pollution incidents continue on the river; with the usual suspects reported once again to Sepa (Scottish Water’s Tillicoultry and Alva WTW). The new Coal Authority mine water treatment facility at Mains of Blairingone, below Vicars Bridge is causing concern as ochre is now finding its way to the river. The Coal Authority contractors are supposed to return this month to attempt to remedy this situation.

River Work Parties

Work Parties have been busy for the last few months attempting to clear vegetation to facilitate access to the river for angling. At this time of year I guess the work parties must feel that it is like painting the Forth Rail Bridge. Approximately six weeks ago they cleared routes through ‘Alva Airfield’ (around the B908) laready the jungle has quickly re-established itself. They have cleared around the ‘Alva Airfield’ , Balguharn, March Glen, Sheardale, The Haugh to Rackmill and Linnbank to Vicars Bridge. This benefits anglers (and dog walkers) access, has helped to reduce the extent of the Himalayan Balsam infestation and involves a huge amount of effort!

Glenquey

By contrast Glenquey has been in excellent form!

The regulars have been ‘busting a gut’ setting unofficial records. Donald MacGregor managed in one session to land 39 trout. Jim Milne by all accounts heading up on Sunday to try and top that …… he couldn’t quite manage to but still landed an impressive 30 trout. Neither will probably be able to keep up with the local Ospreys which once again can often be seen at Glenquey and the other local reservoirs.

Glenquey has benefitted from water at good height allowing full access to all banks. Access has been further enhanced by the sterling work of the work parties over the Winter/Spring who managed to open up access right along the north bank with the help of chainsaws and a huge amount of bloody hard graft!

In May there were 73 angler submitted returns showing 345 caught which represents an average of 4.72 trout/visit with an average weight 0.59lbs [prize winner from the submitted returns was from Sauchie]

In June there were 72 angler submitted returns showing 445 caught which represents an average of 6.18 trout/visit with an average weight 0.65lbs [prize winner from the submitted returns was from Alloa]

Interesting despite there being two modest stockings, a lot of the fish were overwintered or natural breeding stock.

Become a River Monitoring Volunteer

We have been approached by Amanda Malcolm acting on behalf of both Clackmannanshire Council and The Conservation Volunteers, looking for River Monitoring Volunteers.

We are launching a new Citizen Science project and I’d really appreciate if you would be able to circulate this email and attached promotional poster through your network of community groups, Community Councils, volunteers and anyone that may be interested in getting involved in our project – ‘Become a River Monitoring Volunteer’. I can also post hard coloured copies of our poster to be put up around the community. Please just let me know the quantity required and where to post.

 

Project details:

 

We’re launching an exciting new project with Clackmannanshire Council to get local communities involved in recording information about flooding in some of the Hillfoot Burns.

 

Aim: photograph burns to monitor sediment chokes and blockages from key vantage points on Hillfoot burns:

 

  1. Tillicoultry Burn confluence with River Devon
  2. Alva Burn at A91 Road Bridge
  3. Dollar Burn water race + beneath Mixed Leisure Route Bridge to the south

 

The aim is to take a photograph (s) at vantage points chosen by the Environmental Monitoring volunteer to monitor sediment movement, chokes and blockages on the above burns, record river levels via photographs and relate this to information from the local Menstrie Weather website to record rainfall levels.

 

We want to improve our understanding of the interactions between sediment movement chokes and blockages over time in the context of flood risk management and investigate how sediments in these highly dynamic burns may move over time.

 

Through regular monitoring we are able to chart climate change as well as wear and erosion. By undertaking projects such as this we are able to pinpoint pressure sites, such as flooding areas, bank erosion and sediment build up along burns and rivers, which allows us to take action, where appropriate, to protect and improve our local environment for the future.

 

*No previous knowledge of the subject required. TCV will provide survey materials (laminated maps of monitoring sites, recording sheets, clipboard, pencil), training, support and guidance for the project.  

 

Express an interest or to find out more contact Amanda Malcolm, Email a.malcolm@tcv.org.uk or Mobile 07917 460488

 

Please do not hesitate to contact me if you would like finer details of what is involved. I will be working more in the Hillfoots area soon and I will be available to meet various groups and folk to discuss our project, site visit burn locations with volunteers and to go through the recording sheet for our project.

Lamprey watch

July heralds the peak spawning season for the unique parasitic lamprey species the Sea Lamprey. The organisation Lamprey Watch are asking for anglers to report any sightings of Sea Lamprey spawning ……… which is an extraordinary sight

See https://envscot-csportal.org.uk/lampreywatch/2016/03/24/when-where-and-how-to-look-for-lampreys/

To learn more about these amazing creatures, their cousins the River Lamprey and Brook Lamprey (all of which have been recorded in the Devon) and how to report see Lamprey Watch’s website:

The Devon’s other anglers

In my experience the most likely mammal you are likely to encounter in the river other than other anglers, are dogs! I have even been knocked of my feet by an over exuberant Labrador (thankfully towards the bank, avoiding a soaking). Around Dollar and Tillicoultry I have often come across mink scurrying about in the riverside trees and bushes, and occasionally in the river fishing. I know that there are otters on the river, I see their scat but have only caught momentary glimpses of them.

Mick Berney had much more luck this week and was able to snap this lad playing in the river:

12718372_236571610030134_3504948731289739842_n

This area has been a bit of a mink hotspot in the past. One of the good things about the otter is that they will not tolerate completion from mink and their presence will generally drive down the mink population.

Thanks to Mick for sharing the pictures

Glenquey on the opening day of the season

Naturally enough some of Glenquey’s most enthusiastic regulars (Ian, Alan and Donald)  took advantage of the new early start of the season at Glenquey and turned out on Tuesday for the opening day of the season at the reservoir.  By all accounts with the a steady east wind blowing in from a frigid North Sea conditions were a tad bit cold.

By all accounts this is the first trout of the season caught at Glenquey by Alan Graham

SAMSUNG CAMERA PICTURES

He ended up catching a further three trout and lost another three (using a tungsten beaded black nymph) all from the north bank!.

He wasn’t alone the other lads also manage to  land fish!

A great start to the season that bodes well for the warmer months!

Opening of the 2016 season

Well tomorrow is Tuesday 15th March and is of course the opening day of our 2016 Season 🙂

Permits have been distributed to all the usual outlets (see https://devonanglingassociation.org.uk/about-3/permits-2/ )

The day is set fair, perhaps a wee bit of haar early on, then it should be bright with a gentle east wind (though not t-shirt weather). The river looks in pretty good nick and you never know the sun might encourage a few short hatches!

In the unlikely event you catch a spring run salmon please remember all salmon must be released.

A big change this year will be that Glenquey opens for 2016 on the same day as the river. Work parties have been busy clearing shrubs and trees along the north bank opening up more areas to cast when the reservoir is full

SAMSUNG CAMERA PICTURES

If you are spending time on this bank during the season, you can help the work parties while waiting for a rise by bringing along a handsaw!

SAMSUNG CAMERA PICTURES

I am pleased to report that work parties spied a few fish rising out in middle of reservoir last Wednesday.

If you have success on the river or at Glenquey, then feel free to send us your photos/tales and we will post them here.

Best of luck for the 2016 Season 🙂

Engineering works downstream of Vicars Bridge

Anyone travelling along the Dollar-Muckhart road or on the back road from Vicars Bridge to Blairigone will have noticed the large scale excavations underway by the track that runs down to the river by Mains of Blairingone

Mains of Blairingone - 060316

These works are being undertaken by contractors employed by the Coal Authority and are very much for the benefit and protection of the river. The Devon Angling Association are delighted that these works are being undertaken now, having made a number of representations to the Coal Authority over the years.

So what’s going on?

Well the area between the plantation and valley side has for about the last twenty years has been a passive water treatment facility, helping to clean iron contaminated water from old mine-workings before it reached the Devon. It was installed following a serious outbreak of minewater from an old adit in the vicinity of Mains of Blairingone in 1994 which had resulted in serious pollution in the Devon. Anglers alerted the Forth River Purification Board when up to 2km of the Devon downstream became coated in Ochre (the characteristic orange gunge). The small burn it discharged into was rendered devoid of all life over 800m. What had caused this rapid deterioration could never be established but the finger was pointed at British Coal who at the time were working the Lambhill Opencast Coal Site at Blairingone. As was their policy at the time they denied liability for pollution but worked with the Forth River Purification Board to deal with the problem.

The solution was to capture and pipe the minewater under the Blairingone road were it is allowed to flow down a purpose built cascade, before flowing into the shallow lagoons which were allowed to be populated with reeds, rushes and other wetland plants

Cascade

I will save you a chemistry lesson, but essentially the problem with the minewater begins with Fools Gold (Iron Pyrites) which is commonly found in coal, ironstone and shales. It oxidises in contact with air, and as it does it produces heat which accelerates the oxidation (which in certain circumstances can lead to spontaneous combustion in coal, which resulted in some tragic accidents in collieries).  In oxidising the Iron Pyrites is converted to Iron (Fe2) Sulphate which is solvent in water. When the mines are abandoned and the water table rebounds to its natural level, that water dissolves the Iron Sulphide in the first instance Iron (Fe2) Sulphate and then Iron (Fe3) Sulphate. When the soluble iron remerges and comes into contact with oxygen again, it rapidly oxides forming Iron Hydroxide which is the orange gunk known as Ochre.

The cascades are designed to oxidise the soluble iron, which is then carried by the stream and fed into the “reed beds” which filter the water to collect all the iron before the clean water is discharged into the Devon. The system has been very successful in cleaning the water and returning this section of the Devon into a very healthy stream.

We were becoming concerned that the effectiveness of the reed beds was diminishing as the lagoons filled with sediment and that the bunds were not as substantial as they may have been. It is therefore really pleasing that the Coal Authority are taking a ‘belt and braces’ approach to renovating the treatment system.

Members and visitors are urged to visit and contribute to the latest consultation of the Wild Fisheries Review:

https://consult.scotland.gov.uk/wild-fisheries-reform-team/draft-wild-fisheries-strategy

The document takes some reading but the proposed regulations will probably result in fundamental changes to angling in Scotland.

The associated consultation provides you with an opportunity to influence these changes:
