... 38 Practices for Integrated Flood Prediction and Response Systems Instruments and tools: The most commonly observed instrument and tool that DOTs use for flood monitoring are federal stream gages, which are often USGS stream gages. The distribution of instruments and tools used for flood monitoring is shown in Figure 14.
