August 4: Assessing extinction in fishes: Preparing for the extinction of Delta smelt (Sacramento)
On August 4th, the Delta Science Program presents a brown bag seminar from 12pm to 1pm featuring Dr. Peter Moyle and Dr. Jason Baumsteiger.The extinction of a species is a major consideration in balancing water supply and environmental needs. It’s usually regarded as a “yes/no” state. But, its determination can be quite complicated. Drs. Moyle and Baumsteiger will discuss general aspects of assessing extinction, focusing on native fishes of the San Francisco Estuary including the Delta smelt.
August 10: The case for field geology in groundwater investigations (Sacramento)
On Wednesday, August 10, the Sacramento Chapter of the Groundwater Resources Association will host Martin Steinpress, PG, CHg with Brown & Caldwell, will discuss the importance of geologic mapping in groundwater investigations.
Basic geologic mapping is frequently an overlooked tool in the groundwater industry. In this retrospective of one geologist’s 40-year career, several applications of field geology are presented to highlight their importance in contaminant investigations, water resources projects, and mine permitting.

August 17: How San Francisco’s water history created a city against all odds
Water emerges from local springs throughout San Francisco, including in church courtyards, public spaces and in hidden concrete channels under thousands of private homes. Joel’s Seep City project has been tracking and mapping local natural water, but it turns out that a full understanding of water and its effect on our history is impossible. Why?
The Seep City project uses every forensic device from core samples to the jaded familiarity of old timers to sleuth out the water history and dynamics of this very dry city. Cities are made through a chaotic layering of historic artifacts, patterns printed one upon another on natural fabric, each obscuring and sometimes eradicating tatters from the previous scheme. The earliest were responding to a natural environment. Each successive layer became more distant from and therefore beholden to fewer of those geologic features, what are considered to be “original” and “natural” conditions.

August 18: The economics of groundwater management (Sacramento)
The management of groundwater resources for use in agriculture is an issue that reaches far and wide; many of the world’s most productive agricultural basins depend on groundwater and have experienced declines in water table levels. The food consumers eat, the farmers who produce that food, and the local economies supporting that production are all affected by the availability of groundwater. Increasing competition for water from cities and environmental needs, as well as concerns about future climate variability and more frequent droughts, have caused policy makers look for ways to decrease the consumptive use of water. In this talk, Professor Lin Lawell will discuss the economics of groundwater management. There is a socially optimal rate of extraction that can be modeled, measured, and achieved through policy and a complete definition of the property rights that govern groundwater. However, there are several factors that may affect farmers’ groundwater use decisions and behavior and may lead them to overextract groundwater. These include increases in irrigation efficiency, perverse incentives from policy, institutional incentives, and externalities.
August 22: Information fair on water right measurement and reporting
On August 22nd from 10am to 4pm, the State Water Resources Control Board (State Water Board) is hosting an information fair on water measurement and reporting to facilitate better understanding of (and compliance with) measurement and reporting requirements recently adopted by the State Water Board. The purpose of the information fair is to bring together water right holders, vendors, and other professionals employed in the water measurement industry to discuss ways to reasonably and practically measure diversions of water in compliance with the new requirements. State Water Board staff will also be present to answer questions.
Additional information on the fair and the reporting and measurement requirements may be found on the following webpage:
