  Grade:   2 to 3       Rating: river rating
  County:   Roscommon   Date updated:20/04/2010
  Section Length:   0   Version: 6 (History)

Brief River Description

A fast, steep wave, the wave is below a set of sluice gates on the extreme river left that allow the flow through and keep the water levels for the river above the weir.

Directions to the Put-in

Tarmonbarry on the border of Roscommon and Lonford. From Longford Town head out the Westport road. When reaching the Shannon you have to cross a bridge to get into Tarmonbarry. Cross this and take the first left follow the narrow road to the bottom of the lock gates and park up.

There is a large car park at bottom of new housing estate, just follow around and past the lock gate house. Watch out for the deep sunken pool between the white walls in the park (no other barriers or warnings), when the river floods look like a large shallow puddle but will swallow your car!

Get in bellow the weir at the lock gates and paddle over takes 1min to get there.

Directions to the Take-out

The Take out is the same as put in.

River Description

The wave is created by the flow of water over a concrete slide, which is very shallow however under the wave itself is not that shallow at all and it gets very deep behind that again, as represented by the unpredictable nature of the water (boils and what not)..

Get in bellow the weir at the lock gates and paddle over takes 1min to get there

There are big eddies on both sides, river left recirculates.

Directly behind the wave is quite boily and the odd whirl pool pops up here and makes for an interesting paddle back to the eddy.

Local issues

No known access issues, however the lock keeper has requested that people do not walk out to the wave along the wier or climb up on top of the gates. If you wish to get out to the wave on foot - cross the road bridge upstream of the wier and there is a small track down to the wier on the Longford side of the bridge.

River level gauge

For clarity the gates number 1-12 from surfers left to surfers right (river right to left!)

6-12 Open/Level-Unknown: see the pictures

1-11 Open/Level-continuous flow over the weir: nice wave. good left and right shoulder. steep and greenish in the centre with the foam pile left of centre. easier to paddle on than 11 gates and less whirlies. nice wave train going back as far as the island.

1-11 open/Extremely high water: Very wide and very retentive wave forms.It has 3 different sections.River left section is most retentive and has a powerful shoulder.centre section is retentive but friendlier than river left.Centre also has two nice shoulders.River right has a nice shoulder on surfers right but is flushy.

River Hazards

The shallowness of where the sluice gates are.

There is a wall which runs between the mainland and the island downstream of the wave.In high water this wall is submerged and is only a danger if you are capsized.It is responsible for the river left eddie recirculating.

Watch out for fishermen and riverboats.

Some metal girder type things wall the river left eddy and one is submerged but is well out of the flow and once you tap it once in your boat you'll know where it is.

Note: the above mentioned girders are at top of eddy when 1-11 were open and left large deep gouges in boats that hit them when trying to get high enough to carve across.
