Switch flushing and phosphorus
	The Water budget identifies the most important sources for water in a lake and how mach water is gained or lost through each of those sources. It tells us how much water flows through a lake every year.
	For our report, the water budget has two major applications. It is used in the Phosphorus model to estimate phosphorus concentrations in the lake. I will explain this more later.
	Second, the water budget calculates the flushing rate. This important rate tell us how many times the water in the lake is replaced per year. The flushing rate has implications for water quality and for remediation.
	The flushing rate has important implications on water quality. Lakes with high flushing rates cycle nutrients through the system faster. Their water quality also tends to be dependent on runoff and surface water quality rather than ground water quality. A high flushing rate means that the lake will probably respond faster to remediation techniques.
