Basin Wide Recommendations

What watershed and habitat improvement activities would most likely lead toward more desirable conditions in a timely, cost effective manner?

Van Duzen Basin Wide Recommendations
XXX: Highest Priority
Issues Recommendation Activities Yager Subbasin Lower Subbasin Middle Subbasin Upper Subbasin
Barriers to Fish Passage Continue efforts to identify and repair culverts, sediment deltas, or other features that may impair anadromous fish migrations. XXX XXX XX XX
Flow and Water Quality Insure that all water diversions, ponds and near stream wells are operated in a manner that does not impair salmonid habitat. XX XXX XX XX
  To help reduce water temperatures in areas with insufficient streamside shade canopy (ie<50% canopy density) plant willows, redwood, alder, and/or Douglas fir to increase overstory and understory shade canopy. XXX XXX XXX XXX
  In order to help reduce water temperature in tributaries and the mainstem, ensure that near stream forest management encourages growth and retention of conifers sufficient for providing shade and cool micro climate benefits to stream and riparian zones. XXX XXX XXX XXX
  Timber harvests or other land use should be conducted in a manner that does not increase peak flows, accelerate runoff rates, or contribute to excessive sediment inputs to stream channels. XXX XXX XXX XXX
Erosion and Fine Sediment Continue to identify and reduce sources of sediment delivery to stream channels from road systems. XXX XXX XXX XX
  Re-vegetate exposed stream banks to increase bank stability. XXX XXX XXX XXX
  Reduce sediment input from land slides where possible. XX XX XXX XX
  Consider installation of exclusion fencing where livestock have caused significant bank erosion or impaired growth of riparian vegetation. XX XX XX XX
  Use best management practices that prevent erosion and sediment inputs to stream channels during land use projects. XXX XXX XXX XXX
Riparian and Instream Habitat Plant barren nearstream areas with alder, willow, redwood, or fir trees to increase streamside shade canopy and allow for LWD recruitment. XXX XXX XXX XXX
  Add large woody debris and other structure to increase depth, area and shelter complexity in existing pools and flatwaters. XXX XXX XXX XXX
  To increase the number of pools, design and install pool forming structures. XXX XXX XXX XXX
  To address the lack of instream large woody debris and loss of shade canopy, managers should promote growth and retention of large conifers in the nearstream forest and riparian corridor. Management should allow natural recruitment of these trees to stream channels. XXX XXX XXX XXX
Education, Research, and Monitoring Water Temperature monitoring by land owners and responsible agencies should continue at current and additional sites. XXX XXX XXX XXX
  Monitor suspended and in-channel stored sediments by sampling sediment size distribution, turbidity, V*, photo points, etc. XXX XXX XXX XXX
  Utilize CalVeg GIS layers to locate areas where coniferous trees are too small to provide beneficial functions of LWD loading over the near term. These areas should be considered for LWD addition to stream channels to promote desirable pool characteristics, sediment routing and other channel maintenance processes; XX XX XX XX
  Continue efforts to support watershed education programs and watershed, landowner, and road association groups. XX XX XX XX
