Various species of freshwater snails act as intermediate hosts for Schistosoma species. The Bulinus and Biomphalaria snails serve as intermediate hosts for Schistosoma haematobium and S. mansoni, which are the causative agents of urinary and intestinal schistosomiasis in humans, respectively. This study was aimed at determining the distribution and abundance of these snail intermediate hosts along Kwanar Areh Dam, Rimi Local Government Area of Katsina State, Nigeria. Three different sites were selected at Kwanar Areh dam for snail sampling. Snails were collected on monthly basis, for 9 consecutive months using scoop net technique and modified manual hand picking, and were identified using their morphological characteristics. A total of 808 snails were collected from the three sites; 259 (32.1%), 360 (44.6%) and 189 (23.4%) snails were collected from sites A, B and C, respectively. The snails were more abundant during early rainy season and less at its peak. Of the collected snail species, only one species, Bulinus globosus is known from the literature to serve as intermediate host in the transmission of schistosomiasis. No Biomphalaria snails were sampled in the area. Conclusively, this study revealed the presence of a species of freshwater snail that is known to serve as intermediate host in transmission of urinary schistosomiasis in the study area. However, more effort should be put in control of such snails’ population through the use of recommended molluscicides and bioremediation. In addition, public enlightenment and health education on the risk factors and possible transmission of schistosomiasis is recommended
