Rainstorm creates reservoir impoundment behind Sepulveda Dam

Sepulveda Dam, at the headwaters of the Los Angeles River, is the western-most of the U.S. Army Corps of Engineers’ dams operated by the Los Angeles District in the Los Angeles County Drainage Area flood control system. Rainstorms create reservoir impoundment behind Sepulveda Dam. The reservoir reached above 680 feet in elevation Aug. 20. The rising reservoir water surface causes Burbank Boulevard to be closed to traffic. The Corps’ Reservoir Operations Center has notified local law enforcement of the reservoir’s rising elevation.

PUBLICATION NOTICE: SPDAT Rainfall and Streamflow Analysis at Mobile, Alabama

ABSTRACT: This Dredging Operations and Environmental Research (DOER) program technical note (TN) seeks to explain how the Storm and Precipitation Dredging Analysis Tool (SPDAT) can be used to determine dredging response to varying rainfall levels at a given site. This TN will focus on the historical dredging records in the Mobile Bay Ship Channel and rainfall levels in that area. The analysis presented in this TN will form the basis for how the tool methodology can be used to and compare rainfall and dredging records to determine response trends at other sites. The results from the tool analysis can inform dredging managers about how much dredging may be expected under similar rainfall or tropical storm conditions for future cycles.
