Most of us don't have the "luxury" to schedule our fishing around solar/lunar tables, so we fish when we can. That being said, I do believe they work if you get the data for your location (not generalized data from the back of a magazine). Here is a link to what I use:

Max periods occur at Transit times (6 hrs after moonrise or moonset). I usually just check it to see if I am going to be on the water during one of the max times. If so - great, if not - oh well..I still go fishing.

If the max time occurs near the time of sunrise or sunset, that is when I know I shouldn't miss fishing that day.

PS: I checked...they have the data for Summit.
