uses water, creates potentially difficult to treat wastewater, and causes area-wide land cover issues, is proposed in the forested headwaters. Ecological flow protection (10) Ecological flow analyses will likely affect pass-by-flows for water withdrawals and reservoir conservation releases. There may also need to be flow targets in some of the larger tributaries. Climate change (23) Sea level rise will decrease protective wetlands and increase storm surge impact and will affect salinity levels in the tidal river, potentially affecting water purveyors and industries if saline water reaches their intakes. Changes in precipitation could results in more intense storms in winter/spring and drought conditions during summer months. Impacts include increasing intensity of floods, flashiness of streams, reduction in snowpack, extended summer drought, increased water temperature, decreased dissolved oxygen, and increased turbidity/sediment load. Reservoir capacity and necessary operational changes will have to be evaluated. Point and non-point pollution (11) Major water quality issues include nutrient loading and associated decreases in dissolved oxygen. Greater attention will be needed on the influence of the non-tidal system on the water quality of the estuary. Flooding (22) Reservoir management/storage, flood forecasting and flood warnings, flood mapping and flood management are key issues for which management schemes need to be in place. For purposes of ensuring a sustainable water supply in the basin, flood mitigation must be taken into account because of its effect on reservoir storage. Ensemble forecasting and nimble reservoir operations will be needed. Water supply (28) Water supply concerns include: increased upper basin use, salt water intrusion, salt encroachment at the Philadelphia and NJ American intakes, water quality issues, increased drought, need to allocate water for in-stream needs. Integrated water resources management is needed to optimize reservoir operations and to ensure the long-term sustainability of water supplies from both water quantity and water quality perspectives especially in the face of climate change.
