Understanding Cause and Effect



There are dramatic cause and effect relationships between human actions in watersheds and changes to fish habitat – and ultimately – fish populations. Cramer Fish Sciences has pioneered the development of analytical tools that help our clients understand these relationships and their consequences.

Several of our scientists have dual training in watershed sciences and fish biology. We have decades of experience describing the relationships between watershed processes, human activities, riparian and aquatic habitat, and fish populations. We provide our clients unique understanding of potential outcomes of planned management activities. Our services include:

Watershed Assessments

  • Federal watershed guidelines
  • State analysis protocols
  • Unit Characteric Method
  • Limiting factors analyses
  • Cumulative effects analyses

Watershed Characterizations

  • Land use inventories
  • Vegetation cover surveys
  • Climate, geology, and soils
  • GIS data compilation
  • Remote sensing techniques

In-stream Habitat Surveys

  • Compilation of existing surveys
  • State & federal protocols
  • Fish distribution/life history use
  • Channel condition surveys
  • Water quality/in-stream flow
  • Macroinvertebrate/diatoms

Riparian Habitat Assessments

  • Riparian condition surveys
  • LWD recruitment potential
  • Stream shading assessments
  • Stream temperature effects
  • Streambank stabilization
  • Riparian microclimate

Hydrologic Change Effects

  • Hydrology characterization
  • Minimum flow assessments
  • Peak flow flood/scour effects
  • Pulse flow & fish migration
  • Incremental change analyses

Stream Sediment Effects

  • Mass wasting potential
  • Hillslope and road erosion
  • Sediment routing/storage
  • Stream channel effects
  • Effects on fish production
