Arkansas Creek Intelligence by Druidnetworks is a hobbyist project built by one paddler for the Arkansas paddling community. It aggregates USGS gauge data, NOAA radar, and NWS forecasts to provide go/no-go intelligence on Ozark whitewater and the Buffalo River. The data and dashboard are free and always will be.
That said, this stuff costs real money to run: hardware (Raspberry Pis, GPU for model training), residential fiber, LLM API costs for the nightly calibration loop, and time. If you find this useful and want to help offset those costs, donations via PayPal are very welcome.
