Shannon International River Basin District Rivers Report 2009 4.1.3 The Broadford River Plate 4.3. The Broadford River at Killaderry Bridge just upstream of Doon Lough, Co. Clare The Broadford River (Plate 4.3) is a small stream that rises in the Slieve Bearnagh Mountains in south-east Co. Clare. It flows through Doon Lough to join the Anaclare River and later the Owenogarney River, which flows southwards through Sixmilebridge and joins the Shannon Estuary at Bunratty Castle. Tributaries of the Broadford River, joining the main channel upstream of the survey site, flow from the Slieve Bearnagh bog, an area of special significance as the last region of intact open moorland in Ireland (NPWS, 2003b). The survey site was located approximately 0.5km upstream of Lough Doon at Killaderry Bridge (Fig. 4.7). Three electric-fishing passes were conducted using two bank-based electric fishing units on the 12 th of August 2009 along a 40m stretch of river channel. Although all three habitat types (glide, riffle and pool) were represented in the channel, glide was the most prevalent. The substrate consisted mainly of fine material, including gravel, sand and silt. The mean wetted width of the stretch surveyed was 5.1m and the mean depth was 53.0cm. Vegetation present included a number of emergent species as well as various mosses and liverworts. Himalayan balsam, a non-native species 18
The Central and Regional Fisheries Boards which is becoming an increasing threat to river bank habitats in Ireland, was also present on the river banks. A total wetted area of 203m 2 was surveyed. Fig. 4.7. Location of the Broadford River surveillance monitoring site A total of five fish species were recorded in the Broadford River site. Gudgeon was the most abundant species, followed by salmon, European eel, three-spined stickleback and brown trout (Table 4.3). Table 4.3.
