Note: recent addition of minor salt to reduce icy conditions on observation platforms may have affected local conductivity and alkalinity, Note: some difficulty encountered in interpreting color of Taylor strip for hardness. Past observations tended to have values of "0" with today's strip color leaning toward a light purple rather than blue, so estimate of 150 for hardness value, which is suspect. Some waterfowl on lagoon, including mallards, gadwalls, American widgeons. Small number of songbirds including American robins, Song sparrow.
