TigerStream 13: High Definition Stream Survey (HDSS): Transforming Water Resource Management

Welcome to another TigerStream Webinar. This month we are joined by Brett Connell with Trutta Environmental Services. Completion of this webinar earns you one PDH.

ABSTRACT: The High Definition Stream Survey (HDSS) revolutionizes stream corridor assessment by collecting continuous, 1-meter resolution GIS data in a single pass, integrating GPS, video, depth, side scan sonar, and water quality sensors. This provides water resource managers with a comprehensive baseline inventory, extending as far upstream and downstream as needed. Each second of video, linked to precise GPS coordinates, enables identification, prioritization, and monitoring of diverse water resource issues. HDSS supports mapping instream habitat, assessing infrastructure impacts, optimizing mitigation strategies, evaluating restoration outcomes, and delivering the StreamView virtual tour. This presentation showcases HDSS versatility through various completed projects. In Alabama’s Hurricane Creek Watershed, HDSS prioritizes reclamation of streams degraded by historical coal mining, delivering high-resolution data to tackle water quality challenges. The Chattahoochee River National Recreation Area’s 48-mile survey generated GIS layers for depth, habitat, and streambank conditions, a recreational use suitability model, and a prioritized list of restoration sites. Similarly, a 40-mile Wekiva River survey documented Eelgrass extent as well as modeled habitat suitability to advance conservation efforts. The Upper Delaware River’s 80-mile HDSS assessed trout habitat and prioritized restoration, highlighting HDSS adaptability to ecological objectives. These case studies illustrate how HDSS delivers tailored, actionable data to address specific watershed challenges, empowering managers to make informed decisions for restoration, conservation, and sustainable management. By consolidating multiple metrics into a single, efficient survey, HDSS emerges as an indispensable tool for navigating complex water resource challenges with precision and impact.
