Navigation, irrigation, spillway, hydropower are usage and may go in usage=* key. Look at this table : https://wiki.openstreetmap.org/wiki/Proposed_features/Hydropower_water_supplies#Pressurised_waterway_.28pipe_flow_only.29 Canal can go open air, in culvert and free flow tunnel > Waterway=aqueduct looks ok to me, although, in the Wikipedia page for > aqueduct, bringing water to hydro power stations is never mentioned. But I > think it's ok to use that value for that use. > In the same time, systems like "Los Angeles Aqueduct" are called aqueduct and are composed of canals, tunnels and pipelines. https://en.wikipedia.org/wiki/Los_Angeles_Aqueduct That's why I like the definition of Aqueduct like a system and not like a precise building. Am I wrong ? François
