The newspaper says that the rivers, especially in the Neuquen drainage are the lowest in many years because of little rain and the rapid melt of the little snow that fell. The level of the Rio Neuquen this year is similar to that registered in the years 1909, 1968, and 1996. Conditions no better on the Rio Limay and the Rio Collon Cura. At 6 p.m. put out traps east of town between the dirt road and the railroad track a couple of km nearer town than the Aeroclub. Same place as last year. Incredibly dense and diverse mixture of shrubs and grasses: rosa, Scotch Broom, neneo, Colletia, Eryngium, Acaena, Berberis, grass, retamo, a few chacay trees, a coupleof apples in bloom, and a few big palo pichis. Anitas and I each put 25 MS and 25 Sherms, total 100 traps.
