How to improve
on-farm turbidity targets;
reduced water deliveries;
conversion to sprinkler or drip;
convert open ditches to pipe;
BMPs – settling ponds, filter strips, PAM
Notes:
Take home messages: 1) things are better but much work is yet to be done; 2) lots of variability at different temporal and spatial scales – between years, between seasons (nature’s seasons and irrigation/non seasons), between geographic/hydrologic areas, and between individual waters, and within individual waterways; 3) hydrology – timing and quanitity of surface and ground water - strongly influences water quality, and is a driving force in annual rates of some parameters (TSS, turbidity).
