Scenario Planning Overview

![Page 13: Interagency Task Force Meeting - DNR · 5/31/2018 · Discussion of the state’s 2012 drought response, e.g. drilling new wells and the impact on agriculture water demand Provided](https://reader033.fdocuments.in/reader033/viewer/2022050423/5f92390449b5096441751fad/html5/thumbnails/13.jpg)
Why Scenario Planning?
13
Water managers have to plan for the future
One thing that is certain is that the future is uncertain
Given the time and expense to plan for programs and critical infrastructure, it is essential to account for uncertainty
Scenario planning is a structured way to account and plan for uncertainty
![Page 14: Interagency Task Force Meeting - DNR · 5/31/2018 · Discussion of the state’s 2012 drought response, e.g. drilling new wells and the impact on agriculture water demand Provided](https://reader033.fdocuments.in/reader033/viewer/2022050423/5f92390449b5096441751fad/html5/thumbnails/14.jpg)

Steps in Scenario Planning
16
1) Identify major uncertainties that can impact the future
2) Select most important uncertainties as “drivers” of scenarios
3) Develop scenario narratives from combinations of drivers that represent a plausible range of future conditions
4) Measure impacts of scenarios and assess strategies to address impacts
5) Use an adaptive management framework for continuous re-assessment and implementation of strategies

Non-consumptive demand refers to uses that rely on water in the streams, rivers
and lakes for everyday activities. The water is not consumed and is available for
other uses.Consumptive demand refers to water that is withdrawn from the source and
consumed in a way that makes its use all or partially unavailable for other purposes
or uses.

Consumptive & Infrastructure Technical Workgroup Feedback Reviewed approach and methods for each consumptive demand sector and
gave feedback on appropriateness of data Reviewed Woods & Poole demographic projection series MoDNR Water Users Database and Census of Public Water Systems Brought “economic centers” to team’s attention which resulted in a revision to the
methodology
Provided feedback on demand sector naming conventions (Municipally-provided Public Supply changed to Major Water Systems)
Discussion of ways to quantify infrastructure need Provided data and regional reports Collected data regarding recycled water demand offset undertaken by KC
Water Key take away messages:
High diversity in the state – water use, geology, geography Recession impacted population trajectory, future highly uncertain Regionally, southwest Missouri is growing the fastest; urban areas continue to grow Infrastructure needs are great and will only increase

Agriculture Technical Workgroup Feedback
Reviewed approach for livestock and irrigation demand estimations Reviewed pros/cons of potential data sources – MoDNR’s Major Water Users
Database, Census of Agriculture, FSA Provided feedback and guidance on the irrigation efficiency assumptions Discussion of the state’s 2012 drought response, e.g. drilling new wells and
the impact on agriculture water demand Provided clarification that food processing and ethanol plant water use is
included in the Self-Supplied Nonresidential sector Identified additional data sources – Sod Producers Association Key take away messages:
Agriculture need is an important consideration for the state’s supply Use of irrigation water has become more efficient over time Agriculture users have to plan for infrastructure costs as well – e.g. piping and pumps
for irrigation and pond development for livestock watering Agriculture sector also thinks about back-up supply during times of drought much like
public water suppliers do Irrigation is highly reliant on groundwater while livestock relies on both surface water
and groundwater, depending on geographic location; pockets of temporary shortages exist
![Page 34: Interagency Task Force Meeting - DNR · 5/31/2018 · Discussion of the state’s 2012 drought response, e.g. drilling new wells and the impact on agriculture water demand Provided](https://reader033.fdocuments.in/reader033/viewer/2022050423/5f92390449b5096441751fad/html5/thumbnails/34.jpg)
What do the Consumptive Demands By Sector Tell Us?
34
Statewide, the majority of demands are groundwater- Groundwater demands are highest in 6 of 9 basins
- Northern Missouri is more reliant on surface water
- Nearly 82% of statewide consumptive demands are groundwater
- This trend continues into the future
Many public supplies rely on surface water supply- Public supply is the majority of all consumptive demands for surface
water in 6 of 9 basins
- Agriculture is also a major surface water demand, comprising the majority of demands in the remaining 3 basins
Agriculture irrigation is an important consumptive need, especially in the bootheel region; there is potential for this to increase by 17%.

Suggested separating “Aquaculture” and “Wetlands” and adding MDC pumping to “Wetlands”
Many additional studies were identified and provided to the team:

Non-Consumptive Technical Workgroup Feedback
Through meetings, worked to refine language and presentation of sector for the demands chapter – helped to capture what was important to portray
Hydropower TWG member provided direct review of some language for the water plan, more review and input to come
Worked directly with MDC to collect additional water use data and other reports
Provided valuable input into other components of the state plan as well – supply, infrastructure, and water quality; one member suggested use of “median” flow record over “average”
Key take away messages: While not consumed, these sectors rely on the quantity and quality of
water to deliver the services they provide to the economy and environment
These sectors are hugely important to the economic activity of the state

What Do the HUC4 Surface Water Budgets Tell Us?
Flows from out of state are dominant in most basins Consumptive withdrawals are typically:
- < 1% of total streamflow- 1%-5% of streamflow generated in the basins
Supply far exceeds demand at HUC4 scale (no gaps)
57
On an average annual basis:
Gaps in supply and demand begin to appear, but are limited and infrequent
On an monthly basis: Potential Supply

Feedback Received from Technical Workgroups
Consider using median annual streamflow as part of the water budgets (large flow events may skew the average).
Consider impacts to supply that are not captured in the previous 30 years of record.
Consider adjusting demands when comparing to the dry year, since demands may be higher in dry years.
Given that the Missouri River provides water supply to 45% of Missourians, the Water Plan should discuss and emphasize it’s significance.
Double check specific demands (e.g., Springfield and Joplin) to be sure they are appropriately represented.
Northern Missouri’s heavier reliance on surface water supplies (due to poor groundwater quality in deep aquifers) makes it more susceptible to stress during droughts.
