Site Description (to be completed)

Site T7b lies in the Rio Huantan valley at 3625m asl and well above the village of Huantan. River flow in the Rio Huantan is year-round and delivers a significant proportion of river discharge at this point in the catchment.

There is little or no agricultural cultivation along this section of the Rio Huantan. The lack of agricultural activity results from the lack of level ground and dominance of rocks and boulders lying across the steep slopes.

In the upper parts of this sub-catchment agriculture is low intensity and traditional and rural population low, having been subject to rural drift. In the headwaters there is a mining camp at Anexo Atcas. This mine may well impact water quality in the Rio Huantan as might the Mina Corihuami located on the Rio Huantan watershed. Samples from our sample site just above Anexo Atcas are yet to be collected.
