These tools will be used to inform development of flow criteria that sustain specific species, habitats, and beneficial uses. This toolkit may be used to develop policies on how to balance the need for local water supply and still support beneficial uses. In the near term, the outcomes of this analysis can inform decisions associated with proposed wastewater change petitions and stormwater management programs. In the longer term, the outcomes could inform decisions regarding the ability to support beneficial uses not currently supported, in combination with broader restoration planning efforts.
