The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. [1] Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to one hundred. [1] Under the TSI ...
Following is a list of dams and reservoirs in Pennsylvania.. All major dams are linked below. The National Inventory of Dams defines any "major dam" as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3).
The airport's Master Plan [1] includes a water quality section in its Environmental Baseline Study (Chapter 3, Section 3.07). [ 2 ] The master plan positions the airport in Lake Erie Watershed, 9,000 feet (2,700 m) north of Walnut Creek Sub-watershed, 12,000 feet (3,700 m) west of Cascade Creek Sub-watershed, and five miles (8 km) west of Mill ...

An IBI associates anthropogenic influences on a water body with biological activity in the water body, and is formulated using data developed from biosurveys. Biological integrity is associated with how "pristine" an environment is and its function relative to the potential or original state of an ecosystem before human alterations were imposed ...

The larger snail is L. stagnalis with saprobic value 2.0; the smaller one is possibly a Physa fontinalis with a value of 2.4.. The saprobic system is a tool to measure water quality, and specifically it deals with the capacity of a water body to self-regulate and degrade organic matter.
