GENERAL_COMMENTS:
Vacant logging road--the rest of the parcel is protected by natural levee


GENERAL_COMMENTS:
The park driveway has the tidegate, so I marked that as the dike, but both the driveway and Fort Clatsop Road are higher in elevation than the field behind it


GENERAL_COMMENTS:
There is a lot of sand fill in this area that cannot be called a dike, but that is a barrier


GENERAL_COMMENTS:
Labled as levee in soil survey map, but this is likley inaccuate--dredged river in 1960's and much of the sidecast was left on banks

Road is a little higher than the land behind it and there is a tidegate


GENERAL_COMMENTS:
Remnant dike from before main taidegate was installed by ACE--no locals remember this dike

FEMA recognized structure; USACE certified dike; labeled as levee in soil survey maps and USGS topo maps; some fill connecting dike to boat ramp parking lot


GENERAL_COMMENTS:
Lower two-thirds is FEMA recognized structure


GENERAL_COMMENTS:
Adjacent county road is FEMA recognized structure, but is porous and would not protect against flooding


GENERAL_COMMENTS:
Looks to have been abandoned and is now very low, but still has some height near bug hole


GENERAL_COMMENTS:
Culverts allow for some, but very little tidal exchange


GENERAL_COMMENTS:
Built when dike was breached to protect the county road


GENERAL_COMMENTS:
remnant double dike built by logging company to float logs down river--similar structures on other dikes in this area


GENERAL_COMMENTS:
Road is elevated and so funtions as a cross dike


GENERAL_COMMENTS:
There is a small dike protecting the dirt parking lot

ACCESS_TYPE:
The parking lot is a complete barrier, but it would seem that there is access to a pond from a stream


GENERAL_COMMENTS:
May be dredge spoils here, but looks natural from the road


GENERAL_COMMENTS:
This dike is for dregged material disposal.  It is built int he fall and taken down in the spring to allow for more parking space at the port.


GENERAL_COMMENTS:
Really small dike, probably buit to protect the road in case of storms


ACCESS_TYPE:
There is a culvert, but only for drainage--no stream bed for fish to use


GENERAL_COMMENTS:
Road protects pasture to the south from the wetland to the north


GENERAL_COMMENTS:
Dike comes up towards the road, but vegetation veils where it actually ends--was probably built to protect from adjacent wetlands


GENERAL_COMMENTS:
Road protects down river pasture which looks like it may have had a dike around the whole thing at one point

GENERAL_COMMENTS:
Remnant of alterations to Hillcrest Creek; Nadia Gardner at Columbia Land Trust thinks downriver end on east side may have once also been diked


GENERAL_COMMENTS:
River was ditched and straightened and rock was piled on the river bank; there have been a few bank stabilization projects done by Howard Kem and DU


GENERAL_COMMENTS:
Dike never completed; Highly vegetated and not visible from the road--whatever is there is not maintained


GENERAL_COMMENTS:
This doesn't look like miuch of a dike on the LiDAR, but two locals labeled it as a dike on the map, so it is probably altered and enhanced

There is an imminent dike breach where the road ends on the south end of this dike (this dike used to be a road but was closed due to the imminent dike breach) and this dike will no longer be funtional when that breach occurs


GENERAL_COMMENTS:
It is not clear if this berm is natural or man-made, but it is elevated. Some ditches suggest there was some enhancement, but now it is natural. Tidal flow comes primarily through Fisher Slough and not so much the small (10-15') breaches in the berm.

MANAGER:
Pacific County Department of Public Works

DIKING_DISTRICT:
Pacific County Flood Control Zone District #1

GENERAL_COMMENTS:
Is built in front of the road up to the airport


GENERAL_COMMENTS:
Road is elevated, but sand dunes provide natural high ground--these dunes are no longer dynamic due to protection by Clatsop Spit


GENERAL_COMMENTS:
Dift wood against road suggests is offers protection against waves and erosion, but the sand dune is itself a wide, natural levee


CONTACT:
Nadia Gardner, Columbia Land Trust, ngardner@columbialandtrust.org


GENERAL_COMMENTS:
Rip Rap behind the road; Chinook River used to drain out in this area, as well as where it currently does; culvert replacement now allows more tidal exchnage behind the road


GENERAL_COMMENTS:
Dam with tidegates (does not impound water beyond its natural elevation)


GENERAL_COMMENTS:
Labled as levee on soil survey map; Tall grasses and brush on river and land side slopes


GENERAL_COMMENTS:
Labled as levee in soil survey map; railroad trestle adjacent to northern portion


GENERAL_COMMENTS:
Use dredge material to create cells; berms are not used for flood protection


GENERAL_COMMENTS:
Labled as levee in soil survey map; not that high anymore so may not be utalized as a dike


GENERAL_COMMENTS:
Labeled as levee in soil survey map and in ACE 1930s maps; no longer maintained


GENERAL_COMMENTS:
Labeled as levee in soil survey map; locals say there is no dike now (LiDAR does show some elevation, but not much, especially on north side


GENERAL_COMMENTS:
Old slough material from when the internal channels were diked


GENERAL_COMMENTS:
Can still see pretty big remnants of it in the LiDAR


CONTACT:
Dain Ossis at (503) 861-3170 ext. 41(Fort Stevens State Park)


GENERAL_COMMENTS:
The dike is short because the property is on high ground on the Columbia River side; there are plans to restore the property on the north side and remove this dike


ACCESS_TYPE:
Looks like water is getting into old oxbow--culvert


GENERAL_COMMENTS:
USACE certified dike; Labeled as a levee in USGS Topo maps


GENERAL_COMMENTS:
This system looks mainly natural, but in this area there is some grazing and solooks as if there may have been some work done to the river bank


GENERAL_COMMENTS:
Dike is realatively small, but functional

ACCESS_TYPE:
Small tidegate does not allow fish access


GENERAL_COMMENTS:
Labeled as levee in soil survey map; stream at north end was extended through to drain into Blind Slough and has a culvert; bank no longer has much elevation


GENERAL_COMMENTS:
Road is labled as a levee in USGS topo map and other sources, but it is the sand dune to the SW that offers most protection


GENERAL_COMMENTS:
Airport mitigation project; Labled as levee in soil survey maps


GENERAL_COMMENTS:
Road floods during storms, but protects land from waves and erosion; undersized, perched culverts do not allow for full tidal exchange


GENERAL_COMMENTS:
If not for road/levee, the channel opening would be about 400 to 800 feet


GENERAL_COMMENTS:
Road is a little higher than the land behind it and there is a tidegate


GENERAL_COMMENTS:
Remnant dike from before main taidegate was installed by ACE--no locals remember this dike


GENERAL_COMMENTS:
Labled as levee in soil survey map; old road that now resembles more of a trail; this whole area is diked and then filled so the dike itself is no longer very distinct from the area behind it


GENERAL_COMMENTS:
Labled as levee in soil survey map; small dike was build in Januray 2009 after the area was flooded


GENERAL_COMMENTS:
Labled as levee in soil survey map, but is really just fill

GENERAL_COMMENTS:
used to be part of the main dike along the channel, remnant channel appears to be blocked


GENERAL_COMMENTS:
Remnant dike from before main taidegate was installed by ACE--no local remember this dike


GENERAL_COMMENTS:
Might have been built up to offer some protection for fresh water flows


GENERAL_COMMENTS:
Original channel to the east was blocked for better log travel; Area used to be a log dump


GENERAL_COMMENTS:
Labled as levee in soil survey map; dike becomes quite small on the east side of the parcel


ACCESS_TYPE:
natural channel/natural breach in old dike


GENERAL_COMMENTS:
Labled as levee in soil survey map; there was an attempt to take down this dike, bu the cross dike failed, so they rebuilt it.


GENERAL_COMMENTS:
Labled as levee in soil survey map; half owned by Columbia land trust, half is private so it cannot be breached yet


GENERAL_COMMENTS:
Labled as levee on soil survey map; breached by Columbia Land Trust


GENERAL_COMMENTS:
Dike probably degraded due to lack of maintenance after tidegate went in; Incomplete dike, but not heavily used for grazing


GENERAL_COMMENTS:
Looks like road is protecting land upriver from the adjacent wetland caused by either a broken or a blocked tidegate


ACCESS_TYPE:
Tidegate next to the road is still functioning


GENERAL_COMMENTS:
Named "Logger Dike"; Labled as levee in soil survey maps

GENERAL_COMMENTS:
Labeled as levee in soil survey map; no longer maintained as a dike


GENERAL_COMMENTS:
Culverts allow for some, but very little tidal exchange


GENERAL_COMMENTS:
Built when dike was breached to protect the county road


GENERAL_COMMENTS:
remnant double dike built by logging company to float logs down river--similar structures on other dikes in this area


GENERAL_COMMENTS:
Road is elevated and so funtions as a cross dike


GENERAL_COMMENTS:
There is a small dike protecting the dirt parking lot

ACCESS_TYPE:
The parking lot is a complete barrier, but it would seem that there is access to a pond from a stream


GENERAL_COMMENTS:
May be dredge spoils here, but looks natural from the road


GENERAL_COMMENTS:
This dike is for dregged material disposal.  It is built int he fall and taken down in the spring to allow for more parking space at the port.


GENERAL_COMMENTS:
Really small dike, probably buit to protect the road in case of storms


ACCESS_TYPE:
There is a culvert, but only for drainage--no stream bed for fish to use


GENERAL_COMMENTS:
Road protects pasture to the south from the wetland to the north


GENERAL_COMMENTS:
Dike comes up towards the road, but vegetation veils where it actually ends--was probably built to protect from adjacent wetlands


GENERAL_COMMENTS:
Road protects down river pasture which looks like it may have had a dike around the whole thing at one point


ACCESS_TYPE:
Low land not blocked on the southern end

GENERAL_COMMENTS:
Inluded in USACE National Levee Database


GENERAL_COMMENTS:
Any work that was done here was done a long time ago


GENERAL_COMMENTS:
Dike used to connect back to high ground; excess sediment caused dike to be overtopped (in '98), but landowner not given the permit to fix the situation


GENERAL_COMMENTS:
Road causes flooding back-up on land behind it


GENERAL_COMMENTS:
Structure was never connected with like structure on other side of channel


GENERAL_COMMENTS:
Labled as a levee on the National Wildlife Refuges Comprehensive Conservation Plan


GENERAL_COMMENTS:
Just slough material--no structures have been worked on here in over 30 years


GENERAL_COMMENTS:
Labeled as a levee in USACE National Levees Database; the rest of the southern part of the road is also labled as a levee and a remnant oxbow appears to have been blocked, but the road is not elevated


GENERAL_COMMENTS:
Labeled as a levee on USGS topo maps; USACE certified levee

GENERAL_COMMENTS:
There are places on this road where it is not particularly elevated and where it seems wet on the lanward side. The road could fload and/or the tidegates may be broken.


GENERAL_COMMENTS:
Area is filled (may have once been diked); attempts to build a boat launch by WFWS met with anger--now just a gravel ramp

Road was raised to provide protection to the land owner to the north


GENERAL_COMMENTS:
This levee was removed/flattened for the most part by the local diking district after it was put in by Columbia Land Trust


GENERAL_COMMENTS:
Labled as levee in soil survey map; there is a road, but this whole area is diked and then filled so the dike itself is no longer very distinct from the area behind it


GENERAL_COMMENTS:
Remnant of alterations to Hillcrest Creek; Nadia Gardner at Columbia Land Trust thinks downriver end on east side may have once also been diked


GENERAL_COMMENTS:
River was ditched and straightened and rock was piled on the river bank; there have been a few bank stabilization projects done by Howard Kem and DU


GENERAL_COMMENTS:
Dike never completed; Highly vegetated and not visible from the road--whatever is there is not maintained


GENERAL_COMMENTS:
This doesn't look like miuch of a dike on the LiDAR, but two locals labeled it as a dike on the map, so it is probably altered and enhanced


GENERAL_COMMENTS:
Labeled as a levee in the USACE National Levee Database


GENERAL_COMMENTS:
Can see the remnant channels that this elevated area blocks


GENERAL_COMMENTS:
Labled as a levee on the National Wildlife Refuges Comprehensive Conservation Plan, but does not look elevated in this small portion--may just be higher ground


GENERAL_COMMENTS:
Looks like area was worked on and altered in the past

GENERAL_COMMENTS:
Broken up, but tall, sidecast throughout this area


GENERAL_COMMENTS:
Probably just fill or ditch dredging spoils, but quite tall, so appears very dike-like


GENERAL_COMMENTS:
There is a new building here now, so the area has been newly filled. The dike on this side of the lot is still there, but small and in some places, no too much taller than the fill

GENERAL_COMMENTS:
Labeled as levee on USGS topo maps; was probably once a significant dike, but now is no longer mained as one because of the external dikes and pump stations


GENERAL_COMMENTS:
Louisiana swamp; Lower Columbia Watershed Council is planning a restoration project here


GENERAL_COMMENTS:
USACE maps show plans to build a dike, but area is already high ground


GENERAL_COMMENTS:
From the bridge, there does appear to be a dike, but it is covered with blackebrries and the LiDAR suggests that it petters out. There is no dike on the east side of the bridge.


GENERAL_COMMENTS:
Labeled as levee on USGS topo maps; culvert drains the regional detention pond


GENERAL_COMMENTS:
I didn't see a tidegate, but there is a house here and it is dry, so there is either a tidegate or it is all filled in


GENERAL_COMMENTS:
Some fill by the road appears like a dike, but not sure if it was put there to protect the road or is only a dumping place


GENERAL_COMMENTS:
Small private road or trail built on natural levee

GENERAL_COMMENTS:
Vacant logging road--the rest of the parcel is protected by natural levee


GENERAL_COMMENTS:
The park driveway has the tidegate, so I marked that as the dike, but both the driveway and Fort Clatsop Road are higher in elevation than the field behind it


GENERAL_COMMENTS:
There is a lot of sand fill in this area that cannot be called a dike, but that is a barrier


GENERAL_COMMENTS:
Labled as levee in soil survey map, but this is likley inaccuate--dredged river in 1960's and much of the sidecast was left on banks


GENERAL_COMMENTS:
used to be tidegates installed in these dikes before the one at the mouth of the channel went in (installed by ACE)--no local people remember this dike

ACCESS_TYPE:
No need for dike now that tidegate is in


GENERAL_COMMENTS:
Decribed as Brown's Dike in Diking District #1 legal description


GENERAL_COMMENTS:
Breached to allow tidal influence in Trestle Bay

GENERAL_COMMENTS:
There is a small dike protecting the dirt parking lot

ACCESS_TYPE:
The parking lot is a complete barrier, but it would seem that there is access to a pond from a stream


GENERAL_COMMENTS:
May be dredge spoils here, but looks natural from the road


GENERAL_COMMENTS:
This dike is for dregged material disposal.  It is built int he fall and taken down in the spring to allow for more parking space at the port.

Really small dike, probably buit to protect the road in case of storms


ACCESS_TYPE:
There is a culvert, but only for drainage--no stream bed for fish to use


GENERAL_COMMENTS:
Road protects pasture to the south from the wetland to the north


GENERAL_COMMENTS:
Dike comes up towards the road, but vegetation veils where it actually ends--was probably built to protect from adjacent wetlands
