Kawkawlin River Hydrographic Survey

Strategic Data for Federal Maintenance Dredging

Walsh Service Solutions provided critical surveying services for a County-led project in support of a planned federal maintenance dredging initiative. Our team mapped the transition from the Kawkawlin River into Saginaw Bay to facilitate accurate dredging volume calculations and material disposition planning.


Project Overview

  • Value: $142,000

  • Completed: Fall 2025

  • Location: Bay County, Michigan


Project Scope & Execution

  • Comprehensive Mapping: Performed integrated topographic and hydrographic surveys across approximately 42 strategic cross-sections.

  • Dual-Terrain Data: Seamlessly combined land-based topography with underwater hydrography to provide a complete profile of the river mouth and bay entry.

  • Precision Analysis: Delivered high-accuracy data used to determine rough material quantities for removal and to identify appropriate disposal sites.

The Result

By providing a clear “baseline” of the riverbed and shoreline, WSS enabled county and federal stakeholders to move forward with a data-backed dredging plan, ensuring operational efficiency and environmental compliance.
