The CrowdWater game is based on data from the CrowdWater app. App users contribute photos of water levels worldwide. Photo pairs from the same site can then be compared to each other in the CrowdWater game. This helps to verify the incoming data and to improve the quality of water level time series. Players can earn points and every month they can win prizes.
