Walker Scale for Monitoring California Grunion Runs
This metric is used to record the strength and duration of the run. You will also be asked your location on the beach and information about predators, fishing, and weather. 

For details on how to use the Walker Scale, click here.  Below are photos of actual runs at each level and a table with more information.​

W2	hundreds of fish ashore at the same time in a small area or across the beach, fish appear in many of the waves	less than 1 hour	Good, respectable run
W3	hundreds to thousands of fish in one or two areas of the beach, may be locally heavy, may be brief or intermittent	under or over an hour	Strong run
