In 2019, the Environmental Defense Fund (EDF) began working with water managers and landowners in the Rosedale-Rio Bravo Water Storage District (Rosedale) with the goal of creating the first open-source water accounting and trading platform in California's Central Valley. From the start, Rosedale and EDF envisioned expanding the platform to include other water districts in California and beyond.

The resulting Sitka-built, open-source platform enables water managers and landowners to develop more accurate water budgets, simplify water trading, and more efficiently manage water usage. The platform can be expanded with scenario analysis capabilities to analyze and minimize undesirable impact of groundwater usage via integration with Olsson's groundwater modeling decision support tool: the Groundwater Evaluation Toolbox.

We developed this accounting and trading platform because we want to provide landowners and growers with as many tools as possible to manage their water more sustainably and balance their water budget.

We heard loud and clear from landowners that they wanted something straightforward and easy to use. So the accounting portion lets landowners check their water budget very much like they would check their online bank account. The trading portion is similar to Craigslist: A landowner can post an offer to buy or sell water, and a bulletin board shows all the outstanding offers.
