A hydrograph is used to show how the water flow in a drainage basin (particularly river runoff) responds to a period of rain. The hydrographs are an incredibly important and helpful piece of information for fisherman that will give you a glimpse at what the river looks like.
The Bureau of Reclamation operates a network of automated hydrologic and meteorologic monitoring stations located throughout the Pacific Northwest. This network is called Hydromet, transmitting water and environmental data to provide near-real-time water management capability.
