Live panoramic camera in downtown Montenegro, in the Caí Valley of Rio Grande do Sul, southern Brazil. The camera faces east, looking upstream along the Caí River, where the water arrives in the city. It is an independent public-interest project supported by the local community, created to follow the river level and water flow, especially during heavy rain and flood risk. The stream runs 24 hours a day and helps residents and anyone following the weather in the region. Updated river-level data is available at monitoracai.com.br.
