| Topic | Tour: Fife Creek Stream Channel |
This photo is of Fife Creek shows a streambank reinforced with crib logs and cement abutment to prevent damage to the road and ancient redwood trees in the state park. These structures cause confinement of the channel which may change stream hydraulics and degrade habitat conditions. Photo provided by California State Parks Ecologist Brendan O'Neil.
Fife Creek contains several cement sills such as the one pictured here. These structures were built as early attempts to improve stream habitat and reduce bank erosion but currently don't function any desirable way. These structures are planned for removal in 2003 in order to eliminate any effect they may have as a barrier to migration of aquatic life or alteration of natural stream process.

Rip rap, logs and cement bags are used in combination at this site to protect the foot bridge here along Fife Creek. This treatment has been effective from an engineering and erosion control perspective, but has degraded fish habitat. The area will be redesigned in 2003 using bioengineering.

This photo shows the dry stream bed of Fife Creek in summer looking downstream at a road bridge with a cement box culvert. Note the cement sill which spans the channel partially exposed at left and the revetment wall downstream of the bridge. Photo provided by California State Parks Ecologist Brendan O'Neil.
The dry bed of Fife Creek is shown here immediately downstream of the state parks picnic area. Sacks of concrete (sac-crete) and rip rap armor the bank at right and a cement sill spans the channel. Restoration of this area in 2003 using bioengineering will result in a more functional and natural stream channel. Photo provided by California State Parks Ecologist Brendan O'Neil.
