Changes to instream flow are known to be one of the major factors that affect the health of biological communities. Flow alteration can degrade physical habitat and alter water quality, reducing the ability of a stream to support aquatic life. Understanding the relationship between changes in flow and changes in benthic invertebrate communities (a key indicator of stream health) is critical to informing decisions about ecosystem vulnerability, identifying causes of stream and watershed degradation, and setting priorities for future watershed management. Among the range of approaches available for setting flow targets that support biological integrity, a recently completed project in southern California evaluated the Ecological Limits of Hydrologic Alteration (ELOHA) framework to assess the effect of flow alteration on the condition of benthic macroinvertebrate (BMI) communities across the region. The ELOHA framework establishes recommended targets using a process that includes estimation of flow alteration and development of flow-ecology relationships based on the response of biological communities to changes in flow. This project applied to the ELOHA framework to develop regional flow-ecology relationships and targets based on responses in the benthic macroinvertebrate community. The objectives of this project were: 1) Develop a recommended set of flow targets for southern California streams that would maximize the likelihood of maintaining healthy biological communities as indicated by the California Stream Condition Index (CSCI) for benthic invertebrates. 2) Produce a set of tools that can be readily applied to future sites to estimate hydrologic alteration relative to biologically-define targets. This project was led by the **[Southern California Coastal Water Research Project (SCCWRP)](http://www.sccwrp.org/Homepage.aspx)** and developed flow-ecology relationships using data from nearly 600 bioassessment sites sampled over the past eight years. The California Stream Condition Index (CSCI), a measure of biological condition based on benthic macroinvertebrate communities, was calculated at each of these sites (for more information on the CSCI, refer to the **[CSCI Fact Sheet](http://www.waterboards.ca.gov/water_issues/programs/swamp/bioassessment/docs/csci_factsheet.pdf)** and the **[Bioassessment scores map](http://www.waterboards.ca.gov/water_issues/programs/swamp/bioassessment/csci_scores_map.shtml)** that shows statewide CSCI scores and stream hydrologic classifications). The degree of hydrologic alteration at each of these sites was assessed by comparing estimates of present-day and historical flows using a set of regionally calibrated hydrologic models. Differences from historic flow conditions were compared to CSCI scores to estimate the probability of good biological conditions along gradients of increasing hydrologic alteration. The datasets presented here provide the biological and flow metrics calculated for each site to develop recommended flow targets and management priorities at those sites.

The Behavioral Health Public County Profile represents DHCS’s effort to consolidate key county behavioral health information into a consistent and accessible format, helping reduce fragmented data sources and improve transparency. This marks a significant step forward in modernizing and streamlining access to behavioral health data. The initial version of the Behavioral Health Public County Profile provides a high-level snapshot of key information, including –draft Integrated Plan status, county demographics, and homelessness and housing visualizations, as well as a quick reference guide within the display for the public to better understand the information being presented. Using standardized definitions and shared identifiers, the Behavioral Health Public County Profile data is comparable between counties and statewide and will be aligned in public reporting. The Behavioral Health Public County Profile visualizations will be continuously updated as new data sets and behavioral health reporting becomes available. DHCS is releasing the Behavioral Health County Profile in phases based on data availability and reporting timelines. The initial version includes the following sections: * Overview * Demographics (general population and Medi-Cal behavioral health) * Integrated Plan (draft submission status) * Homeless/Housing * Performance * BH Reporting The Behavioral Health County Profile makes county behavioral health data comparable statewide and provides aligned public reporting. It provides a digestible snapshot of Integrated Plans, funding information, compliance status, and performance over time—and will be enhanced with additional data sets so DHCS and counties can work from the same facts at the same time. This marks an important step forward in behavioral health data access just two years after California voters passed the Behavioral Health Services Act (BHSA).
