Cardno JFNew's lake and stream enhancement techniques are based on fundamental principles of nature, providing long-term, sustainable, and economical solutions. Our biologists, hydrologists, and engineers conduct detailed studies of lakes, streams, and their watersheds to design measures to control sedimentation, nutrient runoff, and other factors that contribute to a decline in water quality and natural habitats.
To study and assess streams, Cardno JFNew uses the Rosgen Stream Classification System. We use the principles of fluvial geomorphology and natural channel design to understand channel morphology and hydraulics to successfully design and engineer our project
Characterization
Generalization of stream channel shape, slope, and pattern as formed by relief, landform, and valley morphology
Description
More detailed morphological description of stream type from field measurements of channel form and bed composition.
Assessment
Information on riparian vegetation, fish habitat, and debris.
Validation & Monitoring
Specific measurements of bank erosion, sediment transport, and fish biomass.

Cardno JFNew also performs lake and stream diagnostic studies to identify any problems within an aquatic system. Cardno JFNew collects and analyzes the necessary data available to understand the system's complexity and identify both underlying and explicit issues. A diagnostic study typically includes:
- Historical data review
- GIS watershed mapping
- Pollutant load modeling
- Chemical and biological analysis
The team then undertakes feasibility studies to help ensure that proposed solutions for a lake or stream are physically, economically, socially, and environmentally viable.
