River Ollatrim — a popular fishing spot. About 24 km long. This page shows an hourly bite forecast for today and the week ahead; the algorithm factors in the weather, atmospheric pressure, and the moon phase. The river runs through County Offaly and County Tipperary — the bite forecast is computed for each stretch separately, from the weather of its own region. Across the whole river, european eel, pike and perch are the most active today.
