Problem: Lake Topeka is impaired by high phosphorus concentrations. You have been asked to implement best management practices in the watershed to decrease phosphorus pollution. Available information: Lake Topeka receives three tributaries: Mary's Creek, Myrtle Creek, and Canyon Creek. There is a monitoring station at each creek's mouth, continuously measuring streamflow and phosphorus concentrations (Table 1). Table 1. Physico-chemical characteristics of Lake Topeka' tributaries and their watersheds. Using information from Table 1, calculate: 1) (12 points) Total phosphorus load in kg/ day delivered by each tributary. 2) (12 points) Annual phosphorus yield delivered by each tributary. And use this information to answer: 3) (12 points) Which subwatershed is contributing the most to Lake Topeka phosphorus content? 4) (14 points) It is estimated that the implementation of the BMP chosen for this project costs \$1,150/ha. You have limited resources to lower phosphorus loading to Lake Topeka. Which watershed would you select to implement a BMP if you are only worried about cost efficiency (i.e., grams of phosphorus removed by dollar invested)? Why?
