1. Data Flow CEDEN GeoTracker DPR PUR SWAMP USGS NWIS Water Quality Goals CCAMP Staging Database CCAMP Websites System is intended to be set up using routine automated queries to keep data up-to- date at all times.

2. Side-Bar The automated feed to the website is necessary to make it more easily updated and maintained. The same is true for the My Water Quality data portals. This is why to the extent possible we should store data in CEDEN in forms that are most relevant to our thresholds. This will also improve consistency and support of 303(d) listing activities. Examples include bioassessment IBIs and other summary scores, calculated values like un-ionized ammonia, and summed data like total DDT and total PCB.
