Yes.
If you're talking about surface flow if you could concentrate the flow into a PVC pipe you could measure it by timing how long it takes to fill a known size of container, i.e., a 5 gallon bucket. If it's a lot of flow you could install a flow meter on the pipe.
If it was a well punched into a confined aquifer, AES/Pentair sells various flow meters at various costs that are easy to install.
