FlowGuard wins Rep. Michael Guest’s 2025 Congressional App Challenge in Mississippi’s Third District
Rep. Michael Guest has named Lucas Wang of Madison Central High School as the winner of the 2025 Congressional App Challenge in Mississippi’s Third District. Their app FlowGuard takes in USGS river data, analyzes it, and predicts low-flow risks for the coming week.
When asked what inspired the creation of FlowGuard, Lucas Wang said, “The FlowGuard project is built to help Mississippi’s small water system operators and county officials stay ahead of dry conditions. It provides early warnings about low river flows and easy-to-read, one-page summaries that staff can use to plan and respond. The tool also shows what’s causing the low-flow risks—like weather patterns or upstream changes—so decisions can be made with confidence and transparency.”
The 2025 Congressional App Challenge marked another record-setting year for the program. A total of 394 Members of the U.S. House of Representatives hosted App Challenges in their congressional districts, the highest level of participation in the program’s history. More than 13,800 students from across the country participated, submitting over 4,600 original apps focused on real-world challenges ranging from health and accessibility to education, sustainability, and civic engagement.
The Congressional App Challenge is an official initiative of the U.S. House of Representatives that encourages middle school and high school students to learn to code, explore computer science, and build practical technology solutions for their communities. Each participating Member of Congress selects a winning app from their district, and winning teams are invited to showcase their projects to Members of Congress, staff, and industry leaders at the annual #HouseOfCode celebration on Capitol Hill.
The Challenge is proudly bipartisan and reflects a shared commitment to expanding access to STEM education and preparing the next generation of American innovators for the future workforce. The program is a public-private partnership made possible through funding from the Broadcom Foundation, AWS, Infosys Foundation USA, theCoderSchool, Apple, and others.
The 2026 Congressional App Challenge will launch in May, and eligible students can pre-register for the competition now.
