BACKGR BA GROU OUND ND Chlorophyll-a • In 2008, exceedances of the 40 µg/L chlorophyll-a standard resulted in the lake being listed as impaired. • Nutrient loading to the lake • Chlorophyll-a is the green photosynthetic pigment that plants use to harness sunlight to grow. Chlorophyll-a • Internal nutrient loading in the lake is also an indicator of the amount of algae in the lake. • Atmosphere / weather / rainfall / • While high levels of algae can suggest the presence bathymetry of too much nitrogen and phosphorous, the variables that control algal growth are not only highly complex, • Soils, land use, topography, depth, but they are also dynamic – changing between years light and seasons. • Wastewater, storm events • That is why water quality monitoring and Model els • Sunlight, shape of the lake modeling is required to evaluate the most effective and efficient opportunities for improving • Retention-time, velocity and sustaining the water quality of Falls Lake.

BACKGR BA GROU OUND ND The Consensus Principles • Consensus Principles were established by UNRBA members • Resulted in language in the Rules that allowed for reexamination if certain steps were taken • Provided the framework for the UNRBA re- examination process • Parties agreed to the protection of Falls Lake as a drinking water supply

Key Topics Roundtables

KEY EY TOP OPIC IC ROU OUND NDTABLES BLES Ground Rules • Focus on one conversation. • Please contribute and share the available time with others • Be specific. Use examples whenever you can. • Conversation isn’t commitment. Ask questions and test ideas. We will not hold you to your brainstorming. • Do disagree; don’t be disagreeable.

KEY EY TOP OPIC IC ROU OUND NDTABLES BLES Topic 1 Do you have any questions about the reexamination that weren’t addressed or fully answered during the Q&A session?

KEY EY TOP OPIC IC ROU OUND NDTABLES BLES Topic 2 What type of support from the UNRBA would help you feel prepared to make decisions about nutrient management options?

KEY EY TOP OPIC IC ROU OUND NDTABLES BLES Topic 3 Does anything we talked about during the briefing concern you? Did we leave something out that’s important to your jurisdiction?
