With objective of to diagnose the deterioration socioeconomic, environmental and to evaluate the morphometric characteristics of the microbasin of the Stream Happiness's, the study area was visited, applying itself questionnaires in a sample of the local population. The social deterioration (S) it is of 46%, considered medium, because the education level, feeding and the work conditions are good in the region. For the economical factor (E) it was obtained 48%, high value, because the properties are of average the high productivity, with medium income varying from 5 to 15 minimum wages, besides counting with technical support and to be cooperated. For the technological factor (T) it was obtained 32%, low value, due to the type of local exploration. For the socioeconomic factor (S+E+T) it was obtained 44%, considered loud, that it should limit the conditions of life of the producer, however this is not observed. The calculated environmental deterioration is of 15%, below the expected, being this justified value for the constant fiscalization and investments in the recovery of the area, mainly after the rail accident happened in June of 2003. The microbasin has a more prolonged form, being proven for Ic 060, Kc 0,98 and Kf of 0,15, besides Dd of 1,10 km/km² and the declivity of the 1,20% basin. These associated values show an area without problems of inundations and erosions along the Stream. The indexes obtained don't still demonstrate a high environmental deterioration.
