X | . | . | 8) Species present indicate maintenance of riparian soil moisture characteristics |
X | . | . | 9) Streambank vegetation is comprised of those plants or plant communities that have root masses capable of withstanding high streamflow events |
. | X | . | 10) Riparian plants exhibit high vigor |
X | . | . | 11) Adequate vegetative cover present to protect banks and dissipate energy during high flows |
. | X | . | 12) Plant communities in the riparian area are an adequate source of coarse and/or large woody debris |
Yes | No | N/A | SOILS - EROSION DEPOSITION |
X | . | . | 13) Floodplain and channel charactensucs (i.e., rocks. overflow channels, coarse and/or large woody debris) adequate to dissipate energy |

SOIL / WATERSHED / WATER QUALITY
RESOURCE CONCERNS
BY PRIORITY
#1 Spring Flowing Down Road - Needs to be diverted into existing channel away from road..
#2 Carnaro Creek / Carnaro Spring - Flag a 100 FT Buffer Along Creek / Spring as a NO IMPACT Area and keep Kitchens OUTSIDE of Buffer.
#3 All Snrinn Sites - Flag NO IMPACT Areas Around All Spring Sites.
#4 Do "PFC" Evaluation on Carnaro Creek from Carnaro Spring to Carnaro Lake.
#5 Road Crossing at Carnaro Spring - Exclude Vehicular Travel Across Creek and Evaluate Methods to "Harden" Crossing
#6 Low Level Color Aerial Photo Fight Over Gathering Area - Would he beneficial to collect Big Picture "Pre-Gathering" existing vegetation condition within mead-ows. This would he followed up by a "Post-Gathering" Flight to document damage within meadows whiich could be extensive.
