Mid Klamath area.

Indian Creek Road, north of Happy Camp, CA has patches of
infestation along the road from mile markers 3 to 10. Fortunately
there is only one place where a large infestation is growing near
the Indian Creek (at the 10 mile mark).

If meadow knapweed seeds make it to the water they can be
transported throughout the watershed in one high water event.
Automobiles passing along this road after seed heads form are also
likely to transport this weed throughout the watershed. This
infestation threatens to spread downriver.
