Depends on the creek--is it year round? Depends on the optimum site tree height. Depends on the attitude of the hydrologist and fish head. And, you must know that different land owners/agencies use different colors for things. That's why, before any cutting begins, it is extremely important to have a gathering and make sure everybody understands what is what. Even then, mistakes are made.
Perhaps we could better do a thread on this stuff by venturing over to the Forestry and Logging Forum. In fact, there may already be such threads buried under all the Faller threads.
