Protecting Precious Water: Miami Conservancy District Embraces Data Management in the Cloud

Miami Conservancy District (MCD) was created in response to the devastating floods of 1913 when the Great Miami River burst its banks, killing 360 people and devastating the Dayton region of Ohio. Under the engineering direction of Arthur Morgan, MCD built a comprehensive flood-protection system that was completed in 1922. The system still protects the communities along the Great Miami River and includes five dams, retarding basins and 55 miles of levees. 

Although flood protection is at the heart of the MCD mission, through the years its mandate has expanded to monitor and protect water resources and promote the enjoyment of the waterways through sustainable recreation.

Hydrogeologist Mike Ekberg joined MCD in 2000 as manager of Water Resources Monitoring & Analysis. Prior to this, Ekberg worked at the Ohio Environmental Protection Agency, overseeing regulatory aspects of groundwater contamination. Through the years, he has seen the evolution of data collection and usage, starting with entering raw data into spreadsheets, then using various new software programs of the time, and, in MCD’s case, eventually hiring an IT person in the mid-2000s to manage a SQL database and create custom applications.

“We tried a few different approaches, but never quite felt we were where we wanted to be,” notes Ekberg. “Quality assurance and accessibility were always an issue. When we had requests for information, we gave raw data, which meant the requestor was doing their own analysis. Or if we created graphs of the data from Excel, it was only a snapshot of that one parameter.”

Fortunately for MCD, Ekberg had been with the organization for more than two decades, which meant he knew which data existed and where they likely could be found. This wasn’t the case for IT personnel who were developing custom data applications to improve usability and visual analysis. Every time the IT person moved on, a new person needed to be trained, and they came with different ideas on how to do things. “We ended up with a hodgepodge of data tools that were not really cohesive, which ultimately became the main driver for us to search for a new paradigm.”

The bottom line was that MCD wanted to focus on the science and health of the watershed, rather than manage technology. Ekberg spoke with neighboring agencies in search of a different approach, many of which were using Aquarius software designed by Aquatic Informatics to acquire, process, model and publish water information in real time. 

“The web portal was a really important feature for us, as it would improve data accessibility and relieve us from IT overhead,” says Ekberg. “We liked the results our colleagues were having with Aquarius, and so we made the switch.”


Accessibility through Web Portal

The MCD Water Data Portal (bit.ly/3OxEI9M) has custom dashboards that provide a live view of environmental conditions such as groundwater water levels, stream flow, air and water temperatures, rainfall statistics, or rising reservoir levels. MCD can display information in charts, graphs, maps, meters and timelines, making it easy for users to zero-in on the information they’re looking for. 

“If we have a heavy rainfall, users can set parameters on the portal to see the river level today vs. yesterday,” adds Ekberg. “We also have dials that show the flow vs. maximum capacity of the levee. These tools give our residents and emergency crews direct knowledge they can act on, without having to make a request or wait for the news to come out.”

From an IT perspective, Aquarius is hosted in a secure private cloud that alleviates MCD from having to maintain its own servers and software updates, while providing the latest in data security. As industry and technology continue to evolve, cloud solutions can keep up with changes in the background, ensuring users always have the optimal tools. If there are software issues or training required, the provider has the technical expertise to resolve them.


One Accurate Data Source

“Aquarius has made managing our data much more efficient,” adds Ekberg. “For example, we monitor levels in more than 100 observational wells, and now we have the tools to compare datasets so we can see correlations between river levels and groundwater. We can easily access and track the data to look for longterm patterns and make predictions based on past trends. These contextual relationships were something we could not see before, because the data were siloed in different places.”

As much of the flood-prevention infrastructure is nearly 100 years old, MCD has repair and replacement projects that need to be scheduled. Engineering staff now can go into Aquarius; source the information they need; and use modeling tools to know when’s the best time to repair a flood gate or how much of a low-water-level window they will likely have to repair a concrete dam wall and so on.

The software automatically centralizes vast amounts of hydrologic time-series data, discrete measurement data and complex river-gauging measurements from various locations. It also routinely performs data-quality checks using error detection, data cleaning and flagging tools with automatic bias corrections. 

“These automated tools give us confidence in the quality of our data, which allows us to have greater certainty with our assumptions of the future and how we can best serve and protect the people of the Miami River watershed,” explains Ekberg.

MCD also has integrated data feeds directly from USGS, NWS and other monitoring agencies, giving them the ability to show a bigger picture and reciprocate with sharing their own data for greater collaborative watershed management. 


Public Outreach Made Easy

An increasingly important role for MCD is community outreach to encourage residents to responsibly enjoy the amazing recreational opportunities that the Great Miami River brings to southwest Ohio. For example, fishermen check the water and air temperature through the MCD portal, as warmer waters increase the metabolism of fish so they tend to be more active in searching for food. Cooler waters make them more lethargic and inactive.

MCD engages with the public through its blog as well as interviews on TV and radio, and they do quite a few presentations at schools and community events. “The convenience of going online from anywhere and accessing our data to answer questions or demonstrate the current state of the watershed is very powerful when we are doing a presentation, especially when we can use visual displays to get our point across to the general public,” says Ekberg.

With better access, capabilities and insight into MCD data, the people of southwestern Ohio will continue the legacy of flood protection designed by Arthur Morgan back in 1918 while enjoying and protecting the beautiful Great Miami River.
