Implications of lake augmentation on growth of hydrilla

Abstract

The growth of hydrilla (Hydrilla verticillata Royle) in lake water, Floridan aquifer waten and mixtures of the two water samples was studied. The water was sampled from Lake Hobbs that has been previously identified as a lake that has not been augmented with water from the Floridan Aquifer. Evidence is presented that adding water from the deep wells enhances growth of hydrilla.

Key words:

• Lake augmentation
• aqua‐tic weeds
• hydrilla
