The components include a network of ALERT precipitation and stage gages, plus two ALERT base stations. The system did not perform as designed, so the District and the local sponsor, the Choctawhatchee-Pea River Authority, asked the Hydrologic Engineering Center (HEC) to assist with modifying and improving the system.
