Navigable Waters of the U.S.
Navigable Waters of the United States are those waters that are subject to the ebb and flow of the tide and/or
are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign
commerce (33 CFR Part 329).

Navigable Waters
Navigable waters of the United States are those waters that are subject to the ebb and flow of the tide and/or are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce. A determination of navigability, once made, applies laterally over the entire surface of the waterbody, and is not extinguished by later actions or events which impede or destroy navigable capacity.

Michigan and the Section 404 Assumption
In 1984 a portion of the Corps’ regulatory responsibilities was assumed by the Michigan Department of Environmental Quality (MDEQ) Unless otherwise notified, a separate
authorization from the Corps is not required
![Page 12: Jurisdiction, Wetland Delineations and Datasheets](https://reader030.fdocuments.us/reader030/viewer/2022012719/61b26027d9afd9241d209f55/html5/thumbnails/12.jpg)

When to get a Corps JD
You should request a Jurisdiction Determination any time a proposed project is in one of the Great Lakes, a tributary to a Great Lake, or in adjacent wetlands
When in doubt – give us a call

The Corps Ordinary High Water Mark
The U.S. Army Corps of Engineers Ordinary High Water Mark (OHWM) is a jurisdictional benchmark for administering its regulatory program in navigable waterways under Section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act. The OHWM is the line on the shore coincident with the elevation contour that represents the approximate location of the line on the shore established by fluctuations of water and indicated by physical characteristics such as shelving, destruction of terrestrial vegetation, presence of litter or debris, or changes in the character of soil. The OHWM varies from lake to lake and within each of the connecting channels (e.g., St. Marys River, St. Clair River). A table of OHWMs for several locations throughout the Great Lakes region can be found below. The elevation reference system used to define Great Lakes water levels is the 1985 International Great Lakes Datum, which is commonly known by the acronym IGLD 1985.

Wetland Verification Delineation may be required for
application completeness Considering wetlands during development
of plan helps with avoidance/minimization You may be able to avoid wetland impacts
(possibly avoiding need for permit – we can help you identify areas to avoid) Correctly quantify impacts – minimize
delays later in evaluation

Important Distinctions
The Corps and DEQ are separate regulatory authorities and cannot speak for each other’s programs, verify wetland boundaries, or determine jurisdiction. ONLY the Corps can make a jurisdictional
determination for the Corps of Engineers. A consultant can provide a wetland
delineation but cannot make a final jurisdiction determination.

Data Sheets: Common Issues Correct Data Sheets Missing Information – don’t leave blanks Data point location
► Give accurate coordinates► Provide a map
Inadequate review – if you used the fillable form double check and review Use the comments section – you should
always share your observations

Focus on probable boundaries Which tells you more about the wetland
boundary location?

Use Correct Datasheet Midwest or Northcentral/Northeast
►Most recent: Version 2.0►Hydric soil and wetland hydrology indicators
may vary►Plant indicator status may vary
• Refer to USACE National Wetland Plant List for current taxonomy and indicator status
►Datasheets that predate the regional supplements may not reflect current methodology.

Hydrology indicators Make sure these
two sections are consistent.
If a water table is present, then saturation is also present, usually a few inches above the water table.
If surface water is present, a water table is usually present (0 inches depth).

Hydric Soil Indicators
How do these sections relate?• Refer to the regional supplement
for step-by-step definitions.• Go through each indicator that may
apply for the relevant soil texture (all soils, sandy, or loamy/clayey).
• More than one indicator may apply.

Atypical Situations:Disturbed Areas
Industrial past Covered with fill Excavated Altered by mowing, plowing, planting,
drainage, flooding, etc.

Delineation of Disturbed Areas
Delineate early in the season Use procedures in the manual – and seek
additional resources Describe the problem in the “remarks”
section of the data sheets Provide all documentation used to inform
your decisions
