Too wet for logging?

In California the regulations define "saturated soil conditions".  Operations
are not permitted when soils are saturated.  The definition is as follows:

"1) the wetness of the soil within the yarding area is such that soil strength
is exceed and displacement from timber operations will occur.  It is evidenced
by soil moisture conditions that result in: a) reduced traction by equipment as
indicated by spinning or churning of wheels or tracks in excess of normal
performance, or b) inadequate traction without blading wet soil, or c) soil
displacement in amounts that cause visible increase in turbidity in the
downstream waters in a receiving watercourse or lake.  Soils frozen to a depth
sufficient to support equipment weight are excluded.  2) soil moisture
conditions on soil-surfaced roads and landing, in excess of that which occurs
from normal road watering or light rainfall that will result in the significant
loss of surface material from the road and landings in ammounts that cause
visible increase in turbidity of the downstream waters in a receiving
watercourse or lake.

The foregoing is the legal definition.  Obviously deep rutting or having to
push trucks out with cats would all be indicators of saturated soils.

Don't let them opertate if your land is getting messed up unless, as the others
have mentioned, there are compelling interests to the contrary.
