Abstract
This document consists of a single TMDL for organic enrichment that will result in Lower Pine Lake water quality consistent with the Iowa Water Quality Standards requirements. The organic enrichment impairment is linked to low dissolved oxygen concentrations. In a highly productive and shallow lake such as Lower Pine organic enrichment is associated with algae blooms. These algae blooms are caused by excess nutrients, specifically phosphorous. Measuring chlorophyll concentration estimates algal biomass. Total phosphorous concentration predicts algal biomass in phosphorous limiting conditions. The 1998 assessment of the lake water quality stated that “nuisance blooms of algae and organic enrichment remain significant water quality problems.
