Shannon International River Basin District Rivers Report 2009
The survey site was located at Ballyleague Bridge in Lanesborough, just upstream of Lough Ree on
the border between Co. Roscommon and Co. Longford (Fig. 4.43).
One electric-fishing pass was conducted using four boat-based electric-fishing units on the 16 th of
September 2009 along a 397m length of river channel. The habitat was entirely composed of glide,
and the substrate could not be determined due to the depth. The mean wetted width of the stretch
surveyed was 87.5m, and the mean depth was estimated to be somewhere between 200cm and 400cm.
A total wetted area of 34,738m 2 was surveyed.
Due to the large nature of this site, and the resultant relatively low number of fish captured, this site
will be repeated in 2010 using high-voltage electric-fishing gear.
