JUN-2011 drinking water plant at the spring in operation.
2014 severe pollution incident at Ogulla Spring.


Located at a small church named Ogulla Shrine is a karst spring called Ogulla Spring. We guess the spring was the reason for the church and namesake. This is believed by many to be the Cliabach Well where Saint Patrick baptised the pagan princesses Eithna and Fidelma, daughters of Laoghaire, the High King of Ireland. At the spring is a so-called rag tree, a tree where votive offerings are left with requests for cures. To effect a cure it is commonly believed that one must make three visits and leave something. The offerings include rosary beads, hair coils, baby dolls, religious statues, and children's toys.

The spring is a typical karst spring and thus responds rather fast to heavy rains. Also, it is fed by surface water swallowed in numerous swallow holes, sinking streams, estavelles and thurloughs in the area, and is therefore vulnerable to phosphate and nitrate pollution. The water reappears after only a few days underground almost unchanged. Nevertheless, it is used for drinking water by the Mid-Roscommon Co-Operative Society Limited, a private Group Water Scheme. They built a reservoir and treatment plant at the spring which is in operation since June 2011.
