Santa Cruz River Heritage Project Flow Reduced to Remove Sediment

Beginning today, April 23, the Santa Cruz River Heritage Project (SCRHP) will have reduced flow so that the Pima County Regional Flood Control District can remove accumulated sediment from the river channel.

Tucson Water and the Flood Control District are working closely together and with the University of Arizona’s School of Natural Resources and the Environment to minimize the impact on wildlife and protect as much of the riparian vegetation as possible that has grown since the Heritage Project launched in June 2019.

The project could take up to three months. The accumulated sediment has significantly reduced the carrying capacity of the river, with more than 10 feet of sediment buildup in some places, increasing the flood risk to hundreds of adjacent residences and businesses. The agencies are taking several steps to mitigate the environmental impact of the project.
