Surface Water
Surface Water Studies & Stream Analysis
Measuring, modeling, and managing the water you can see — from stream gauging and floodplain analysis to water quality and availability studies.
Surface Water: Where Hydrology Meets the Field
Surface water is the most visible part of the hydrologic cycle — and often the most contested. Stream flows, floodplains, water quality, and availability are at the center of permitting decisions, water rights disputes, infrastructure design, and environmental compliance. Anderson Water Consulting brings both the field instrumentation and the analytical rigor to characterize surface water systems accurately.
We conduct stream gauging, water quality sampling, and floodplain surveys across the Black Hills and the broader region. Our surface water reports meet the technical standards of state and federal agencies, and our principals have supported surface water matters in regulatory proceedings and litigation.

Capabilities
What We Deliver
Streamflow Measurement & Gauging
Current meter and acoustic Doppler measurements of stream discharge, stage-discharge relationships, and continuous monitoring program design and installation.
Water Quality Sampling
Field sampling and analysis for physical, chemical, and biological parameters — supporting permit applications, baseline studies, and compliance monitoring.
Floodplain Analysis
HEC-RAS hydraulic modeling, floodplain delineation, and FEMA LOMA/LOMR applications for development projects and infrastructure design.
Water Availability Studies
Analysis of surface water availability, seasonal flow variability, and drought-year conditions to support water rights applications and supply planning.
Instream Flow Studies
Determination of minimum instream flow requirements for aquatic habitat, recreation, and downstream water rights using accepted methodologies.
Sediment & Erosion Studies
Channel stability assessments, sediment transport analysis, and erosion evaluations for stream restoration, bridge design, and land disturbance permits.
