Limits of Jurisdiction
Non-tidal waters: In the absence of adjacent wetlands, the
jurisdiction extends to the ordinary high water mark, or
When adjacent wetlands are present, the jurisdiction extends beyond the ordinary high water mark to the limit of the adjacent wetlands.
When the water of the United States consists only of wetlands the jurisdiction extends to the limit of the wetland.

Changes
Permanent changes of the shoreline configuration result in similar alterations of the boundaries of waters of the United States. Gradual changes which are due to natural causes and are perceptible only over some period of time constitute changes in the bed of a waterway which also change the boundaries of the waters of the United States.

Changes
For example, changing sea levels or subsidence of land may cause some areas to become waters of the United States while siltation or a change in drainage may remove an area from waters of the United States. Man-made changes may affect the limits of waters of the United States;

Watershed Approach
- Considers entire systems and their constituent parts. Recognizes that healthy main stem stream reaches are only as healthy as the many tributaries of which they are composed.
- Identifies specific functions lost or impaired within watersheds and focuses on replacing those functions.
![Page 42: One Corps Serving the Army and the Nation U.S. Army Corps of Engineers Pittsburgh District Regulatory Branch Allen Edris (412) 395-7158 allen.r.edris@lrp02.usace.army.mil.](https://reader036.fdocuments.net/reader036/viewer/2022062321/56649f295503460f94c41ea6/html5/thumbnails/42.jpg)

Watershed Approach
- Relies on information and input from other federal, tribal, state, and local resource management programs.
- Recognizes the role of zoning, regional planning, land use initiatives, and factors of local interest.

Mitigation Plans
When preparing stream mitigation plans, it is important to document baseline conditions to substantiate that particular mitigation elements and/or techniques area needed and are appropriate for the given situation.
