Commercial- Pony Camp.  Horse trail across stream @ mid-pt.  Not effecting stream very much.


Comments:
SLUMPING ON LB COMMON.  CROP ON EACH SIDE IS HAY.  BALED AND BEING MOVED OUT ALREADY.


Comments:
A lot of slumping occurring. Reach is downstream of a road crossing and flow of water from uphill runs into stream (see photo of plume).


Comments:
AWFUL.  HAD TO MOVE POINT BECAUSE OF BEAVER DAM UPSTREAM, TRASH- EXTREMELY DEGRADED!


Comments:
Site moved 30m upstream due to unsampleable road culvert.


Comments:
Mid pt. is a wetland but has definite channel and flow. Trib entering on LB u/s of mid pt. ~25m


Comments:
This is a large 1st order stream, more like a 2nd.


Comments:
Sort of skunky smelling.  Los of rip-rap on RB approx 200ft.  Site in the middle of golf course.


Comments:
Small trib and drainage enters stream 5m d/s of mid pt. Some oily sheen.


Comments:
Cattle have direct access to stream.  Site moved upstream due to beaverpond flooding.


Comments:
Old pasture, unused at present. If was in use there are no buffers except for some trees. RB has multiple large bank stumps.

Lots of trash on the way down to site.  Old and new.


DEQ_Site_Description:
Assess impacts on water quality from Town of Purcellville


Comments:
ROAD CROSSING BELOW SEGMENT.  NO BUFFER, ON EITHER SIDE.  A FEW TREES, WILLOW, AND BERRY BUSHES.  SEEMS LIKE LANDOWNERS TRY & KEEP IT NICE, MIGHT BE INTERESTED IN TREE PLANTING.


Comments:
LB is largely left unshaded.  Large swath of erosion on RB approx. 25 m in length @ 50-75m.  Pond on LB at 75m.  Stream is flooding.  Possible ATV road across stream at 60m.


Comments:
Stream doesn't flow across road.  There is a farm drainage area that runs under road and into stream.  Large tadpoles, sunfish, and minnows observed.


Comments:
SIGNIFICANT LAND CLEARING JUST UPSTREAM.  Resident noted that stream dries up in summer.  Some big deep pools.  Dragonfly larvae observed.


Comments:
Dr. les Goldsmith would like a report.  His half is part of Conservation Group so he has nice buffers, and fences to keep the sheep out.  Upstream neighbors do not.  Mostly multiflora rose and grass and horses have access to stream.  So riparian Veg zone Width is an average of 19's for downstream half, and poor upstream half.


Comments:
Rock wall on hill above RB. Small terra cotta pipe possibly wetland drainage to preserve wall. Could not find source of pipe though.


Comments:
Site moved downstream of road crossing.  Not any riffle to speak of, very little shade.


Comments:
Landowners indicated beaver alert.  No signs of recent beaver activity in site.  Few chewed down trees.


Comments:
Commercial land use refers to Church ( fro lack of better category).


Comments:
site extended approx. 5m due to unsampleable road crossing.  Active horse pasture downstream from segment.  Riffle!


Comments:
POND W/ LOTS OF GEESE DRAINS INTO SFCC DOWSTREAM OF SEGMENT.  AREA OVERGROWN W/ MILE-A-MINUTE.  25M SECTION OF 7 FT HIGH SHEERED OFF BANK ON LB.  LANDOWNER PLANTED TREES 16 YEARS AGO.  SOME AREAS OF STREAM BANK ARE GRASSES AND UNSHADED, BUT AREA IS NOT USED SO IS A BUFFER.


Comments:
NO FORESTED BUFFER HERE- ONLY LAWN W/ A FEW SCATTERED TREES


Comments:
Pasture empty at present.  But recently used and horses have direct access to stream.


Comments:
Lots of large boulders, crumbly substrate with smaller cobble embedded into it.  Very large island divides top 1/2 of reach.


Comments:
Very secluded area.  Lots of toads in forest on way to site.


Comments:
Landowner said entire parcel used to be cattle pasture.  Him and volunteers planted trees in the 70's.  Now forest.


Comments:
SITE IS ADJACENT TO REGIONAL PARK; A LOT OF GRAZING LAND & ANIMALS ARE PRESENT (COWS, BULLS, LLAMA, SHEEP).


Comments:
Moderate/severe erosion on outide bends.


Comments:
Currently no cattle- but they have direct access to stream and have been here recently.  No understory shrubbery.


Comments:
spring fed. Sediment depositon occurs, at bottom 50m of reach, when Potomac is high it flows into stream and drops sed. and leaves


Comments:
HORSES CURRENTLY IN STREAM.  DIRT-GRAVEL ROAD (PRIVATE) PASSES THROUGH STREAM @ MID PT.


Comments:
Site mved due to pond at end of stream.  Moved approx. 10m.  Site in the middle of active horse pasture.  Benthic habitat "vegetation" sampled were overhanging grasses and SAV.


Comments:
DEER AND GROUNDHOGS SIGHTED.  LOTS OF SUNFISH.  HIGH SEDIMENTATION, TOP OF REACH IS A CULVERT (HOMEMADE).  CATTLE UPSTREAM.  2 SNAPPING TURTLES.  BEAVER DAM AT 25M.


Comments:
Man-made falls @ 25m.  Major sedimentation going on upstream of falls.  Smells like eggs.  Northern Water Snake noted at site.


Comments:
Site adjusted downstream to account for 5m of unsampleable road pipes.  -picture of pipes is from upstream side.  It was too thick to get a good picture of downstream side of pipes.


Comments:
Both LB & RB have approx. 2m high patches of erosion.  Not noted as erosion site since areas are at most pnly a few feet. Can see RB in photo.


Comments:
VERY LOW WATER.  DID HIGH GRADIENT SHHET AS IF THERE IS WATER SUFFICIENT FOR A "FULL STREAM".


Comments:
ALMOST NO RIPARIAN BUFFER ON LEFT BANK-  GRAZING ON RIGHT BANK


Comments:
Right side of stream is unshaded, no buffer.


Comments:
Up & downstream photos reveal roal culvert w/ alteration.  5 corrugated metal pipes. Approx 2 ft in diameter.


Comments:
Stream is changing. Tree fall combined with deposition is changing stream shape.  Sinuous and braided.


Comments:
WETLAND AREA IS SPRING FED.  LAND/O ASKED US TO CHECK WQ - TEMP:14.4, COND:  0.287, DO 6.9, pH 5.87.  WETLAND IS KNEE DEEP, STINKY MUCK.


Comments:
Water turbid, and running high.  Cattle have direct access to stream.


Comments:
SITE MOVED DUE TO PERMISSIONS.  UNDERCUT BANKS PREVALENT ON RB.  SEDIMENT COMES FROM UPSTREAM DEVELOPMENT, FILLED IN A POND, AND STREAM.  ALSO LOGGING 10 ACRES OF TREES OFF TOP OF MOUNTAIN CAUSED TROUBLE W/ SPRINGS THAT FEED LAKES AND STREAMS IN AREA.


Comments:
THIN RIPARIAN BUFFER.  HORSE PASTURES AND RESIDENTIAL ARE ADJACENT.


Comments:
Cattle have direct access to stream. Bullhead catfish-2 1/2 " in length.  Undercut banks and bank slump areas common on both banks.


Comments:
New coordinates due to permission.  Downstream  of road crossing culvert, fenced off.  Half of stream is unshaded.


Comments:
Fence debris around mid point.  Easy  to get around.


Comments:
Mid-pt. crosses gravel driveway- behind pond


Comments:
Recent flooding evident.  Cows have access to stream, upstream from reach.  Onadequate buffer on left, but fenced off from pasture.  Police dog training school.


Comments:
TIRE, OTHER DEBRIS PRESENT IN STREAM.  REDDISH-HUE TO SEDIMENT.  STREAM VERY TURBID/CLOUDY, LOTS OF SEDIMENT PRESENT.


Comments:
Water seems cloudy.  Very overgrown, small stream.


Comments:
LOTS OF LARGE BOULDERS, LARGE ROCK FRAGMENTS PRESENT IN STREAM


Comments:
STREAM IS VERY OVERGROWN NEAR ROAD, HONEYSUCKLE AND POISON IVY.


Comments:
SPRING FED PONDS, ONE ON OTHER SIDE OF STREET.  CATTLE HAVE DIRECT ACCESS TO POND AND STREAM.  CATTLE WERE IN POND UPON ARRIVAL.  STREAM IS VERY SMALL, SEDIMENTED IN, AND TRAMPLED BY CATTLE.


Comments:
very sandy stream bed. Landowners building structure appears to be both residence and business. Approx. 0.2 milefrom midpoint.


Comments:
Small trib enter reach u/s on LB, from mid pt. ~5m


Comments:
Note new coordinates due to permissions.  2 springs feed into stream above mid-pt.  2 major slump areas, and a lot of undercut banks on outside bends.


Comments:
A LOT OF MILE-A-MINUTE.  ANIMALS ARE FENCED OUT OF RIPARIAN AREA DUE TO STEEP BANKS AND SLUMPING.


Comments:
Coordinates taken where could get satellites.


Comments:
site moved upstream ~20m because of fence/conflicting properties. Site flow is high from recent rainfall. 50% left bank is lawn. Note the lower score in rparianveg. zone.


Comments:
SLIGHTLY BETTER QUALITY HERE THAN 201 OR 203. NO COWS IN STREAM AND THIN RIPARIAN BUFFER (BUFFER WIDER ON R BANK)


Comments:
COWS LIKELY HAD ACCESS TO STREAM IN THE PAST.  EVIDENCE OF BANK IMPACTS, COULD ALSO BE FROM DEER- ONE SPOTTED AT SITE ON ARRIVAL.


Comments:
COORDINATES TAKEN IN DRIVEWAY, NO SATELLITE IN STREAM.


Comments:
Very large, with bedrock and boulders dominant.  New coordinates noted.  Only found dead crayfish.
