Barriers to Fish Passage. |
Continue efforts to identify and alleviate fish passage impediments at culverts or other road crossings. |
Improve fish passage by modifying debris accumulations. |

Flow and Water quality. |
Insure that water diversions used for domestic or irrigation purposes bypass sufficient flows to maintain all needs of fishery resources. |
Reduce water temperatures. |
Plant willows, redwoods, alder or fir trees to help reduce water temperature in areas with insufficient shade. |
Check for adverse impacts from cattle to water quality. |

Erosion and Sediment Reduction |
Continue to identify and reduce sources of sediment delivery to stream channels from road systems. |
Stabilize eroding stream banks with appropriately designed structures and/or by planting vegetation. |
Investigate methods to increase culvert capacity and pass stored sediments at first low water crossing. |

Riparian and Instream Habitat |
Increase depth, area or shelter complexity in pools, by adding LWD or combinations of boulders and LWD. |
Design and install pool forming structures to increase the number of pools. |
Consider thinning hardwoods to increase growth of conifers where riparian forest is strongly dominated by hardwoods and shade canopy will not be adversely affected. |
Consider planting nearstream areas with alder, willow, or fir trees to increase streamside shade canopy and allow for LWD recruitment. |
Consider limiting cattle access to stream channel by installing exclusion fencing. |

Education, Research, and Monitoring |
Conduct relative abundance and distribution surveys for juvenile steelhead and resident trout. |
Monitor Water Temperature especially in upper reach of Little Van Duzen. |
Monitor suspended and in-channel stored sediments by sampling sediment size distribution, turbidity, V*, photo points, etc. |
Conduct stream habitat surveys. |
