I believe that each age class from a hatchery are clipped the same and then distributed to the various lakes. Sometimes lakes could be stocked with fish from multiple sources due to shortages (due to disease at one hatchery for instance),so different clips could occur between the lakes.

It looks to me that the differences between the Canandaigua and Seneca clips are just a reflection of the fact that Lake Trout can live 20 years or so and that Seneca has been stocked that long and Canandaigua has not.
