Governors’ MOU

Acknowledges the Ohio River Basin as a vital, shared water resource

Serves as States’ endorsement of a Commission role in water resources management

Support expressed by four states: IN, KY, OH, WV Efforts ongoing to gain further support

Climate Change

Regional Temperature/Rainfall Trends

Jim Noel (National Weather Service)

Temperature Trend in Ohio has

been for warming from 1976 to recently

Most significant warming has occurred in the winter season

Precipitation Trend in Rainfall has

been for increased rainfall from 1976 to recently

Much of the increase has been in late summer through autumn

Climate Change Summary

In some parts of the country, climate models do better than others. The Ohio Valley is a tough place as the jet stream flows through here.

The climate will change. Variability will likely increase. Predictability will not be high in our region.

With all of the uncertainty, developing innovative and flexible adaptations will be key.

Ohio River Basin Climate Change Pilot Study Ohio River Basin Climate Change Pilot Study (Debbie Lee, US Army Corps of Engineers)

•The Ohio River Basin Climate Change Pilot Study addresses potential threats to water resources management and infrastructure posed by CC.•The Corps study partners with the ORB Alliance through joint formulation of mitigation and adaptation strategies.•A permanent CC working group will be established in the ORB Alliance during the study. •NOAA, USGS, USEPA, USACE, Battelle, TNC, UC, UNH and MU are represented on the 18 person team.

Future Uses of Study FindingsFuture Uses of Study Findings

Establishment of permanent working group in the ORB Alliance to assist

water management agencies in further understanding of climate

change effects and implementing adaptation strategies

Increased general knowledge of the potential effects of climate

changes on ecological systems and infrastructure used for flood

control, water supply, hydropower, navigation and aquatic species

enhancement.

Identify opportunities for modifications to flood control structures that

address adaptation to climate change effects during planned

rehabilitation for Dam Safety issues.

Raising public awareness of climate change effects and potential future

operational changes in water management needed to mitigate for or

adapt to impacts.
