WETLAND DETERMINATION
Background Information and Methods
Cottonwood Consulting completed a wetland delineation of
the Waterglenn P.U.D. northeast of the City of Fort Collins
(T 7 N and R 68 W) in Larimer County, on March 30 and 31,
1994. This survey was conducted at the request of the City of
Fort Collins, and to fulfill the requirements of Section 404
of the Clean Water Act regarding the delineation of wetlands
prior to potential development activities. This parcel
consists of approximately 160 acres of open land bounded by
I-25 on the east, the Larimer and Weld canal on the west, and
east Vine Drive on the south.
Wetland delineation was completed using the techniques
and methods specified for 'routine on -site delineations' in
the publication Corps of Engineers Wetlands Delineation
Manual (1987). Following the analysis of site
characteristics, the wetland/upland boundary and sample
points (S1-S12) were flagged with fluorescent orange tape and
pin flags, respectively. The results of the field work are
summarized in the following paragraphs. Copies of the data
sheets completed in the field are included with this report.
A map which displays the approximate delineation line is also
included; please note that it is not to scale, but is
intended to show approximate locations of wetland boundaries
and sample sites.
Wetland mapping also includes portions of the
transitional zones between upland and wetland; these areas
are typically comprised of a mix of upland, wetland, and
species found in both areas.
In addition to this delineation, an "atypical" situation
and possible wetland area was identified adjacent to the
slough. An "atypical" situation as defined by the Corps of
Engineers occurs where ..."positive indicators of hydrophytic
vegetation, hydric soils, and/or wetland hydrology could not
be found due to effects of recent human activities or natural
events." In this case, plowed field areas adjacent to the
delineated wetland boundary fit this description.
The dashed line on the map indicates the additional potential
wetland area within the plowed field, and is based on:
1. Larimer County soil survey information
2. topographic contours
3. the configuration of the existing wetland
4. presence of FACW vegetation at the edge of the plowed area
Because of the linear configuration of the slough, any
additional wetland area within the plowed fields is not
expected to be extensive. An exact determination based on
analysis of soils below the plow line will require more
extensive field work. This work will be conducted according

Along the middle and northern portions of the eastern side of
the slough, some transitional areas with mottled soils and
brome are included within the wetland boundary. Sample site
11 typifies yet another mixed area, with Juncus spp. and
wheatgrass present in varying proportions. Soils here are
moderately mottled with color of 10YR 3/2.
Soil Survey Information
The soils mapped onsite by the Soil Conservation Service
(Soil Survey of Larimer County, 1980) are as follows:
Map unit 63. Longmont clay. With 0-3% slopes, these deep,
poorly drained soils formed in alluvium from clay shale.
They are found on flood plains, terraces and in valleys.
This soil type underlies the entire Cooper Slough area.
Map unit 22. Caruso clay loam. With 0-1% slopes, this deep,
somewhat poorly drained soil is found on low terraces and
bottomland. This soil type is found adjacent to the southern
edges of the slough.
Map units 73 and 74. Nunn clay loam. These deep well -drained
soils with slopes of 0-3% are found on high terraces and
fans.
Map unit 95. Satana loam. With slopes of 1-3%, these deep,
well -drained soils are found on uplands and high terraces.
The remainder of the area surveyed was determined to be
upland because of vegetation and hydrologic characteristics
observed at the site, and the soil characteristics noted in
the above descriptions.
pectinata), thistle (Cirsium spp.), dock (Rumex crispus), and
Eleocharis spp. A 6-inch layer of black organic matter
overlying saturated and heavily mottled low-chroma soil was
characteristic of this sample site.
South of the wide depressional area at the north end of
the Slough, surface water flow is the central feature of the
wetland area. The substrate beneath the water is sandy;
masses of green algae and other aquatic vegetation are
found here. The west bank of the stream is fairly steep in
the northern portion of the slough, and supports dense
vegetation including thistle, prickly lettuce, sedges, and
saltgrass (Distichlis spp.). Patches of prairie cordgrass,
thistle, and sedges (sample site 4) grow in highly organic
(low chroma) soils (10 YR 2/1). Sedges, Eleocharis and
Scirpus americanus are found in sometimes thick patches
along the water's edges where the channel widens slightly;
sample site 5 is an area of cattails (Typha spp.) and sedges
in saturated gley soil at a wider area within the channel.
Proceeding south along the west side of the stream,
several similar areas were found as the bank became more
level and the stream channel became wider. About halfway
down the length of the slough, aquatic plants were no longer
present in the stream. Patches of prairie cordgrass and
sedges became more abundant, as typified by sample site 6,
with strongly mottled low-chroma soils.
The southern portion of the slough adjacent to the Vine
Drive right-of-way is a broad, highly disturbed mosaic of
wetland, upland and transitional areas. The presence of
mottled low-chroma soils, and FACW species, notably prairie
cordgrass, were used to delineate much of the eastern edge of
the slough. Sample site 8, near Vine Drive, is typical of
the vegetative mixture; species include prairie cordgrass,
sedges, thistle, Kochia scoparia, and common pigweed
(Chenopodium album). Soil was 10 YR 4/1 in color, with
mottles. Overland water flow from north to south was
apparent. At the water's edge, and within the zone of
saturated and inundated soil, sedges, Eleocharis, and Scirpus
americanus were the dominant species. On the upland side of
the delineated wetland, brome (Bromus spp.) and wheatgrass
(Agropyron spp.) were dominant; soil color was 7.5YR 4/3
without mottles.
. Sample site 9 is one type of transitional area in this
portion of the slough, again indicative of prior disturbance
at this site. Wheatgrass is dominant, with some areas of
alkali sacaton (Sporobolus airoides) and saltgrass. Soils
are 7.5 YR 4/3 with 3/2 mottles. Brome is found toward the
upland, and cordgrass and Scirpus americanus are found closer
to the stream. Another type of transitional area is typified
by sample site 10, with prickly lettuce, thistle, wheatgrass,
Kochia, and pigweed. Soils are 7.5YR 3/2 with mottles.
to procedures recommended by the Denver COE office, and will
be completed in the near future. Results will be appended to
this report.
Threatened Species
It should also be noted that Cooper Slough contains
potential habitat for the federally threatened Ute Ladies' -
Tresses orchid (Spiranthes diluvialis). Although ,a survey of
the Slough in 1993 did not produce any specimens, it has been
recommended that an additional survey be conducted in 1994,
since the plant does not flower every year.
Wetland Delineation
Most of the site has been cultivated and is presently
plowed field; the site has also been grazed in the past.
Cooper Slough runs through the southwest portion of the site,
with a perennial water flow from north to south. It is a
linear wetland area averaging approximately 100 feet in width
and 2300 feet in length. Its source of water is most likely
seepage from the nearby canal. The Slough has been impacted
by surrounding land use: it has been grazed; it has received
agricultural runoff from surrounding fields; an access road
runs along the southeast portion of the slough area; and corn
husks from past crops bave accumulated in the wetland up to
depths of 12 to 15 inches in some areas.
Cooper Slough consists of several wetland plant
communities interspersed in some areas with upland
vegetation. The northern portion is a bowl -shaped
depressional wetland area containing large areas of reed
canary grass (Phalaris arundinacea) and bulrush (Scirpus
americanus) (sample site 1) bounded along its outer edge by
brome (Bromus spp.) and prickly lettuce (Lactuca serriola).
Soils were 7.5YR 3/2 with mottles. Several small hills are
found just southwest of this area; these may have been .
created by prior land disturbances and support a mixture of
upland and wetland species (sample site 3) including sedges
(Carex spp.), dock (Rumex crispus), thistle (Cirsium spp.),
Kochia scoparia, Chenopodium spp., prickly lettuce (Lactuca
serriola), and scattered milkweed (Asclepias speciosa). Soil
color was 10YR 4/2.5 with slight mottling; this area was
considered a transitional portion of the wetland complex,
and was included within the wetland boundaries. Sample site
2, at the bottom of the bowl -shaped area, contained Scirpus
americanus and sedges, with heavily mottled low-chroma soil
color. Water was present in the upper 12 inches. Evidence
of overland water flow in this portion of the slough was
apparent in a north to south direction.
East of sample site 2, the vegetation was more varied
but also strongly incicative of wetland conditions (sample
site 12). Species included prairie cordgrass (Spartina
