    Metropolitan Water District

    Los Angeles
    Associate Resource Specialist (present)


    I work within the Implementation Section of Met's Water Resources Management group, which ensures the year-to-year viability of Southern California's imported water supply. Our team performs economic and scientific studies related to the Colorado River system, the State Water Project, water purchases and transfers, storage and banking, and regional water conservation. My current focus is a long-term study of agricultural water use in the Palo Verde Valley, including policies to reduce consumptive water use while maintaining the local farm economy, and the development of new techniques to measure and analyze crop water use.


    RMC Water & Environment

    Santa Monica
    Water Resources Planner (2015)

    At RMC I worked with local California agencies on projects relating to sustainable groundwater management under SGMA, Urban Water Management Plans, demand forecasting, recycled water policy, and conservation ratesetting. Working with one of RMC's principals, I coauthored a $500,000 Sustainable Groundwater Planning Grant proposal for San Joaquin County which was fully funded by DWR. The work plan incorporated innovative surface+groundwater modeling using IDC, and ag water use estimation using remotely-sensed ET data.
    Client: Long Beach Water Department
    Masters Thesis Group Project (201415)

    Between 2012 and 2015, California experienced some of the driest years on record, in which the governor declared a statewide water emergency and State Water Project deliveries were reduced to 5%. Early appeals for voluntary conservation failed; it took a mandate from the governor in April 2015 to finally motivate Southern California's urban water agencies to reduce their water consumption by 25% below 2013 levels.
    We identify the current system of shortage allocation in urban Southern California as one area where the incentives for voluntary conservation could be stronger. The current system creates a 'share-the-pain' approach in which all agencies are asked to cut back by a more or less equal percentage, regardless of their previous conservation efforts (or lack thereof).

    A rights-based approach to water allocation and trading would allow water agencies that proactively invest in conservation to receive a larger dry-year allocation, making it possible to store the water they save for their own use or sell the water to other cities during dry years. This system would create incentives for agencies to conserve even in wet years. Working with our client, the Long Beach Water Department, our team investigated the possibility of a market for inter-city water trading in Southern California. While ag→ag and ag→urban water transfers are becoming commonplace, robust urban→urban markets are still rare. The service area of the Metropolitan Water District of Southern California provides an ideal substrate for such a market due to its shared infrastructure, which eliminates the conveyance issue and enables 'paper water' trades. See our website for more information.


    We presented our research at AWRA's Spring Conference: Water for Urban Areas: Managing Risks and Building Resiliency (Los Angeles, 2015).


    Our team also participated in a panel entitled Market-based Approaches to Water Management at the 2015 California Water Policy conference.


    Long Beach Water Department

    Conservation & Planning Intern (2014)

    7% of the water used by municipal residents is lost to leaking indoor and outdoor plumbing, an unacceptable amount during the current California drought. I sought to improve the Long Beach Water Department's automated leak detection protocol, which is triggered whenever a customer receives a bill than is higher than normal.

    Using statistical techniques like time series analysis, I analyzed the water department's customer data to identify usage patterns that represent different types of leaks. The goal was to create an algorithm that can spot leaks as they occur and identify when customers repair them.

    I follow a specific philosophy of design in much of my work, taking inspiration from many pioneers of technical communication:
    Crisp, policy-relevant writing following the principles of Joseph Williams (Style: Toward Clarity and Grace) and Steven Pinker (The Sense of Style)
    Data Visualization
    Thoughtful graphical presentations of evidence based on the principles of Jean-Luc Doumont (Trees, Maps and Theorems), Edward Tufte (The Visual Display of Quantitative Information, Beautiful Evidence), John Tukey (Exploratory Data Analysis, Visualizing Data), and Stephen Few (Signal)
    Statistical Thinking 
    Rigorous thinking about causality and experimental design, informed by the writings of Fisher (The Design of Experiments) and Tufte (Data Analysis for Politics and Policy), including Bayesian approaches per John Ioannidis (Why most published research findings are false) and Nate Silver (The Signal and the Noise)

    Can tree rings tell us anything about historical salmon returns on a freshly un-dammed river? A proposal for NSF's Geobiology and Low-Temperature Geochemistry grant program

    "The ongoing removal of two ~100-year-old dams on the Elwha River in Washington state provides an opportunity to study whether the sequestration of marine nitrogen in tree rings can provide a useful historical record of salmon returns. By measuring δ15N, δ18O, and C:N ratios in increment cores from Sitka spruce, we plan to observe the migration of marine-derived nitrogen through the ecosystem in real-time, shedding light on open questions about the utility of tree rings as a tool for studying salmon returns."

    Saving Lake Chad: An analysis of the proposed Oubangui-Chari water transfer

    A legal, scientific, & ethical analysis of a controversial proposal in central Africa

    "Imagine a plan to divert water from the Canadian Rockies to the Great Salt Lake in Utah, and you’ll have some idea of what Sanusi Imran Abdullahi is proposing. Abdullahi, the Nigerian-born executive secretary of the Lake Chad Basin Commission, is in charge of saving one of the world’s most endangered water bodies, central Africa’s Lake Chad. Threatened by a perfect storm of climate change, overwithdrawals, and a rapidly growing population that depends on fishing and farming, Lake Chad has shrunk to 1/10th of its size over the last 50 years.


    With some scientists predicting the lake will disappear entirely by 2030, Abdullahi is now banking on a dramatic last-ditch effort to rehabilitate the basin: a massive diversion of water from the Congo River watershed, 1000 km away, into the Chari River which feeds the lake. If completedan increasingly unlikely prospect given violence in the Central African Republicthis would be the largest interbasin water transfer in the world."

    Mitigating the impact of climate change on water quality in Lake Tahoe

    A policy memo

    Lake Tahoe is famous for its pristine water clarity, but rising temperatures threaten to increase sediment and benthic phosphorus loads, clouding the water with suspended particles and microorganisms. This memo makes three recommendations for reducing the sediment and nutrient loads to the lake:
    1. Greater stormwater control using detention ponds and bioswales
    2. Voluntary sediment & nutrient reduction programs for ski resorts and golf courses
    3. A more stringent Total Maximum Daily Load for water clarity which takes into account the predicted effects of climate change

    Agricultural Water Conservation in California: Challenges and Opportunities

    The passage of SBx7-7 in 2009 was a milestone for urban water conservation in California, mandating a 20% reduction in urban demand by 2020. But given that agriculture accounts for 80% of consumptive water use in the state, will we see a similar law targetting agricultural conservation? The new groundwater law is a good start, but what are the other economic and policy instruments available to reduce agricultural demand?

    The city of Caldwell, Idaho wanted to redevelop its city center into a riverfront park, but decades of industry had left the area contaminated by TCE and other chemicals. Columbia Technologies was selected to perform a 3-week-long MIP investigation to locate chlorinated contaminants in the soil and groundwater. In the field, I worked with the consultant and the drillers to map an area spanning several city blocks.
