More about Double Setting

Dam crossovers are very obvious and easy to spot.  Except where theft is an issue or someone might disrupt your traps, dam crossovers are hard to beat.  Where beaver have multiple dams forming several ponds, they will, of course, have a point or points where they cross their dams nightly.  The crossover usually corresponds with the stream channel.  Placing a Comstock Cage trap at the base of the dam works well.  The trap will be set upside down as usual on the angle of the dam with the upper end of the roof of the trap about even with the water level and lower end submerged.

If there are multiple dams it certainly won't hurt to set all of the crossovers.  Where there is but one crossover you can increase your odds and speed the trapping process by simply setting two cages side by side.  Recently I did just that and took a 45 pound and 30 pound beavers side by side.
