I spent some time late this afternoon checking out Triadelphia Reservoir.    Initially found three Gadwall in the cove by the dam but the majority of ducks were north of the Greenbridge access road.  Found four scoter candidates but they mostly kept their heads tucked which complicated getting an id.  Eventually, they ended their naps and was able to identify them as female/imm Black Scoters.  There were several other rafts of ducks:  21 Bufflehead, 20 scaup sp, 3 Ruddy Ducks, and 10 Mallards.  As I was leaving, a Common Loon called and an Osprey dove into the water nearby.  Nice way to end the afternoon.
