{"abstract":"With the construction of Seven Oaks Dam, during and immediately after storm events, water flows into the pool of water impounded behind the dam may be turbid. Once water is impounded behind the dam, all water flowing in the Santa Ana River that enters Seven Oaks Reservoir must pass through that impoundment before being released at the dam. To the extent that water impounded behind the dam can have a higher level of sediment or algae than water flowing in the Santa Ana River below the Southern California Edison (SCE) No. 1 Powerhouse, the quality of water released from Seven Oaks Dam into the Santa Ana River may be reduced. The purpose of the study is to evaluate the potential impacts, if any, of the Seven Oaks Dam regarding downstream water quality and to characterize upstream water quality. This will entail characterization of the water quality conditions that existed prior to dam construction and determination of how or whether the dam has contributed to water quality impairment as part of the \"baseline conditions analysis\". After the analysis, future studies would be determined with the resource agencies, Local Sponsors, and Stakeholders.","action":"Notice of intent.","agencies":[{"raw_name":"DEPARTMENT OF DEFENSE","name":"Defense Department","id":103,"url":"https://www.federalregister.gov/agencies/defense-department","json_url":"https://www.federalregister.gov/api/v1/agencies/103","parent_id":null,"slug":"defense-department"},{"raw_name":"Department of the Army; Corps of Engineers","name":"Engineers Corps","id":142,"url":"https://www.federalregister.gov/agencies/engineers-corps","json_url":"https://www.federalregister.gov/api/v1/agencies/142","parent_id":103,"slug":"engineers-corps"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2006/05/19/06-4685.html","cfr_references":[],"citation":"71 FR 29128","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"A public scoping meeting has been scheduled for Wednesday, May 31, 2006 at 7 p.m. at the San Bernardino County Flood Control District Offices, 825 East Third Street, San Bernadino, CA 92415.","disposition_notes":null,"docket_ids":[],"dockets":[],"document_number":"06-4685","effective_on":null,"end_page":29129,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2006/05/19/06-4685.xml","html_url":"https://www.federalregister.gov/documents/2006/05/19/06-4685/intent-to-prepare-a-draft-environmental-impact-statement-for-the-seven-oaks-dam-water-quality-study","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/06-4685?publication_date=2006-05-19","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2006-05-19/06-4685/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":35,"last_updated":"2026-04-10 04:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2006-05-19/pdf/06-4685.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2006-05-19","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2006/05/19/06-4685.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-11-12T19:24:33Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":29128,"subtype":null,"title":"Intent To Prepare a Draft Environmental Impact Statement for the Seven Oaks Dam Water Quality Study, San Bernadino County, CA","toc_doc":"San Bernardino County, CA; Seven Oaks Dam Water Quality Study","toc_subject":"Environmental statements; notice of intent:","topics":[],"type":"Notice","volume":71}
