In this Keywords: study, we consider the formation, deposition, preservation and dilution of mass-independent volcanic sulfate oxygen and sulfur isotopes (MIVS). Using the isotopic compositions of the sulfates, we construct a mixing model that demonstrates that isotopic mass-independence the main source of sulfate in Lake Tecopa is mass-dependent sediment-derived sulfate (MDSDS, >77%). sulfate However, ash beds still preserve up to 23% of MIVS that initially had undiluted Δ17O value around 8‰, and aerosols Δ33S as low as −0.35‰, and Δ36S up to 1.08‰.

    1313 Sherman Street, Room 718 Denver, CO 80203 P (303) 866-3441 F (303) 866-4474 TO: Colorado Water Conservation Board Members FROM: Kevin Houck, P.E. CFM Watershed & Flood Protection Section DATE: November 8, 2019 AGENDA ITEM: Consent Agenda Item 2. November 20-21, 2019 Board Meeting - Floodplain Designations Background: Consent Agenda Item 3 includes 7 new floodplain studies that are proposed for CWCB action. Staff is requesting Board designation and approval for these items. A brief summary of the study is presented in the attached document. CWCB staff performs technical reviews of floodplain information to assure the Board that the information complies with the requirements of the CWCB’s “Rules and Regulations for Regulatory Floodplains in Colorado,” 2 CCR 408-1. The attached document provides a further discussion of legislative authority and responsibilities delegated to the CWCB. The CWCB’s designation and approvals greatly assist local communities in meeting the statutory requirements of the State and the regulatory requirements of the National Flood Insurance Program. Additional supporting information for this item is attached. Requested action for Floodplain Resolution 19-703: Staff recommends that the Board: 1) designate and approve the detailed 100-year and 500-year information and 100-year approximate floodplain information contained in said report within Chaffee County, City of Salida, Town of Buena Vista and Town of Poncha Springs, and 2) authorize staff to prepare a floodplain resolution to be signed by the Director and transmitted to Chaffee County, City of Salida, Town of Buena Vista, Town of Poncha Springs, and FEMA. This action is recommended in order to meet statutory requirements.
