    Camcor River, Birr, Co Offaly


    OPEN SEASON: March 1st to September 30th

    The Camcor River rises on the western slopes of the Slieve Bloom mountains and is the primary tributary of the Little Brosna River where it joins at the Castle Demesne in Birr town a distance of about 12 miles.

    This is a spate river. It has an interesting character, meanders quite a bit immediately upstream of Birr and then alternates between long flats with occasional broken rifled areas, glides and pools. With a rolling gravel bed it is an important spawning river for salmonid species (salmon and trout). Resident local trout of up to 0.75lbs are present but are generally smaller in size at about 6 – 10ozs. The river receives migratory runs of Lough Derg trout, locally known as ‘Croneen’ on route to spawn. Scientific investigation has found that the Croneen trout are a unique species of Brown Trout to the Birr area.

    The first summer floods see croneen entering the river upstream of Birr where angling is best. Good angling stretches are located from the Maltings in Birr upstream through Sandymount,, Syngefield as far as Killyon. Palmers Flats is one of the best stretches on the river and extends from Syngfield (Green) Bridge’ to Clonbrone (Red) Bridge. This stretch has lots of open water and holds very good stocks of fish, particularly during the summer months. With drainage undertaken on the river many years ago, the steep banks upstream of Clonbrone ( Red ) Bridge can be difficult to negotiate – hence most fishing is confined downstream of here.

    ‘Croneen’ average from 1lb to 1.5lbs with fish of 2 – 4lbs and over are possible. Wet fly fishing is very effective on a clearing flood and thereafter at night time when fish tend to shoal back into the pools exhibiting similar habits to sea trout of which they closely resemble. Lure flies such as a Bloody Butcher 8,10’s Peter Ross 8,10’s, Silver Invicta 8,10’s and Black Pennell 8,10’s are effective. During a flood typically Size 8 is best and is also fished after dark. A good pattern on a dropping flood is a Thunder & Lightning. Lure flies tied in tandem style are also fished in high water. During a dry spell and low water conditions a size 10 or 12 fly is best. A 9.5 foot fly rod loaded with a medium sink tip fly line is used. Generally the best time of year is July to September depending on weather conditions and runs of fish.
