Hydrologic modification for habitat improvement in the Finger Lakes: Pre-Project Report Number 3, 1994

The Finger Lakes Habitat Rehabilitation and Enhancement Project
(HREP) is intended to improve winter habitat conditions for fish
in a series of interconnected backwater lakes of the Mississippi
River near Alma, Wisconsin. Winter habitat requirements
(temperature, flow velocity, and dissolved oxygen) for the target
fish population in the Finger Lakes have been defined and
limnological efforts have been aimed at quantifying the
spatial-temporal patterns and interrelationships among water
movement, oxygen, and temperature.  The progress to date
(preconstruction) has included detailed investigations into (1)
system hydrology (including dye-tracer studies), (2) oxygen supply
and depletion, (3) temperature regime, (4) aquatic vegetation
distribution, composition, and abundance, (5) macroinvertebrates,
and (6) target fish species movements and food base.  This report
is the third in a series addressing preconstruction conditions. 
The report summarizes results of studies conducted during 1993.
