The uncontrolled morning-glory spillway in the left abutment consists of a concrete intake structure, concrete conduit, and concrete chute and stilling basin.

The concrete dam includes eight bottom outlets, a spillway and four power intakes and conduits, a stilling basin, headrace and tailrace channels.

That same report indicates the existing dam structures ( gate tower, stilling basin, uncontrolled spillway and outlet works ) remain in operational condition.

The stilling basin lies about 3 km below the dam of the Oker Reservoir and about 2 km below the Romkerhalle power station.

The stilling basin can store up to 204, 000 m?of water and its main purpose is to regulate the water level downstream.
16.
Stepped spillways are useful for flood control, increasing volatile organic compound ( VOC ) removal and reduces the spillway length or eliminates need for stilling basin.
17.
The south intake feeds water into the dam's spillway, from which it travels through a sluiceway to a stilling basin at the southern base of the dam.

This project was completed in 2006 and involved overlaying the existing earthen dam with a layer of roller compacted concrete, approximately in thickness, and constructing a new RCC stilling basin.

Miller Stilling Basin, the most upstream of the facilities, is the location point from which flow from Carbon Canyon Channel is diverted into Carbon Canyon Diversion Channel or Carbon Creek Channel.

About once a year in spring, the reservoir runs over into the spillway, generating massive whitewater down the cascades to the stilling basin that draws crowds of spectators for a few days.
