Right now, I don't think any one of us can make an accurate prediction of what is going to happen. It depends on air temperature, rainfall amounts, timing, and temporal distriution across much of the Susquehanna watershed. If I could predict that accurately a couple of months out, I would have skills that would make me a rich man. What we can be sure of is that the upper Bay will have temperatures, sediment loads, and water quality that are either average or above or below average over the next couple of months, years, or decades.
Conowingo Dam has been benefiting the water quality of the upper Bay ever since it was built . Unfortunately, at some point in the very near future, it will reach its maximum sediment storage capacity and then we will see water quality in the upper Bay become more variable and degraded as it responds to storm-generated sediment loads from the agricultural areas of Pennsylvania.
