NWP 11: Temporary Recreational Structures

Temporary buoys, markers, small floating docks, and similar structures placed for recreational use during specific events such as water skiing competitions and boat races or seasonal use, provided that such structures are removed within 30 days after use has been discontinued. At Corps of Engineers reservoirs, the reservoir managers must approve each buoy or marker individually.

Acreage limit

The 2026 rule states no acreage limit for NWP 11. Eligibility turns on the activity description in the rule text and the general conditions that apply, not on a numeric cap.

Pre-construction notification: Not required

NWP 11 carries no notification clause in the 2026 rule. Activities authorised solely under this permit do not need to file a PCN under general condition 32.
