? Recent rain and spring growth have improved the appearance of all sites. The water in the creeks and in the wetlands appears relatively clean, and there is less visible litter. ? The physical and chemical results are correspondingly fair or better (except the turbidity measurement for Valley Creek). ? The invertebrate samples from the wetlands were taken mostly from the reeds and were clogged with algae and silt. They had low invertebrate abundance and low variety. ? Flow measurement at site 2 (Scotchmans Creek) was done in a narrow part of the creek downstream of Valley Creek. This was done to avoid problems with wind causing large errors at the usual site, which is the broad concrete outlet channel of the wetlands. (Valley Creek contributed only about 5% of the measurement).
