Descriptions of station types:

1. Long-term stations are sampled monthly every year. The goals for this monitoring are to reveal trends and characterize water quality.

2. Basin stations are sampled monthly for one year only. We may return to a basin station every five years. The goals for these stations are to characterize water quality and address specific needs for monitoring data.
