A TREE FALLING THROUGH THE WATER WILL LIKELY GLIDE AT A FORTY-FIVE DEGREE ANGLE UNLESS IT IS WEIGHTED HEAVILY OR LOWERED WITH A ROPE

Allow for the glide path if you want perfect results. The deeper it must fall, the more likely it will glide at a 45 degree angle. Also, keep in mind that if it's dropped too close to a ledge, it could slide down the ledge and drop off into very deep water.
