| Study Name | Lake Mini-Monitoring TP and Secchi |
| EIM Data Entry Review Status | Not Reviewed |
| Study Type | Routine ambient monitoring |
| Study Purpose | Collect TP and Secchi during routine site visits for aquatic plant monitoring (Jenifer Parsons. This addendum adds the activity of collecting total phosphorus water samples to the Quality Assurance Project Plan for Aquatic Plant Monitoring in Washington Lakes and Rivers. Documenting phosphorus levels will provide additional information in determining the overall health status of the lakes sampled. |

| Study Comment | Phosphorus is a critical nutrient required for all life. In appropriate quantities, phosphorus supports the primary algal production component of the lake food web. In many lakes, phosphorus is considered the “limiting nutrient”. This means that the available quantity of phosphorus controls the pace at which algae is produced in a lake. This also means that any modest increase in available phosphorus can cause rapid increases in algal growth – potentially leading to a reduction in the lake’s beneficial uses such as swimming and boating.
By adding sampling of total phosphorus to the Washington State Department of Ecology’s Aquatic Plant Monitoring Program, we can obtain important additional information on the status of lakes in Washington. |
