Who We Are

Our Mission: To provide our clients with accurate and complete river data and the best river mapping and analysis tools available.

Our Goals:

Empower all concerned and interested parties, federal and state, public and private, with a greater understanding of river environments to ensure optimal management of this most vital shared resource.
Enable river professionals, fisheries, and wildlife biologists to better understand, manage, and restore endangered species habitats by providing river data collection and analysis services..
Enable hydro-electric power generation facilities to optimize management of stream flows in order to meet the needs of all constituents, including power consumers, agricultural, transportation, and recreation interests, and wildlife habitat managers and biologists.

Let us introduce ourselves

Freshwater Map

Freshwater Map is the result of Dr. Mark Lorang’s 30-plus years of research in oceanography and limnology. Dr. Lorang is a pre-eminent expert in the study of sediment transport and 3-D-dimensional flow analysis in aquatic environments.

Mark’s extensive experience measuring flow and depths in aquatic environments and how those metrics contribute to a better understanding of river ecosystems has created better solutions to the central challenge for river professionals:

How do we best manage public aquatic resources for all parties including wildlife managers, hydro-electric dam operators, agricultural, recreation, and transportation interests?

A little about our methods and technologies

How We Do It

Using the most sophisticated equipment available, proprietary software, and a dedicated team of highly skilled river technicians, GIS specialists, and software programmers, Freshwater Map defines and maps aquatic environments by collecting millions of data points both above and below the water.

Our highly detailed data empowers river professionals with actionable insights into river habitats. With this information, river professionals are able to more efficiently, effectively, and economically meet the needs of their respective constituencies, and ensure the health of their rivers. In the traditional flow-modeling sphere, our data collection services are of great benefit, allowing flow modelers to base their models on empirical data, gathered directly from the water itself.
