eoontail (Ceratophyllum) occurred both years in Rice Pond and other 
ponds in the river bulrush marsh. No wild rice (Zizania) was found 
in 1958; yet in 1959 fair stands appeared around HKice Pond and two 
other ponds. Sago pondweed was much more common in 1939 than in 1938. 
Big Lake and Goose Pond, Banner.--Eig Lake contained ex- 
tensive American lotus and river bulrush beds. In 1938 marsh smart- 
weed was abundant about the lake, but in 1939 most of the smartweed 
was replaced by river bulrush. ‘Two small patches of wild rice ap- 
peared in 19359. 
In 1938, Goose Pond had the largest bed of duck potato in 
the Illinois Valley. Eecause of high water during the growing season 
of 1958 and 1939, resulting in submergence of the plants, this species 
was largely replaced in 1939 by American lotus and coontail. Patches 
of white water lily were materially reduced in size in 1959. 
Clear Lake, Mason County.--Clear Lake was practically barren 
of duck food plants during 1938. In the open water, scattered plants 
of sago and long-leavedcd pondweed occurred, while along the shore a 
few beds of spike rush (Eleocharis), river bulrush and duck potato 
were found. During the Summer of 1939 the water of this lake receded 
to such an cxtent that most of the lake was a mud flat. These drouth 
conditions were due to the fact that the pool of the La Grange Dem did 
not extend far cnough vostream, and the flow through the valley was 
tess than in previous years. 
On this extcnsive mud flat such véiuable duck food plants as 
duck millet, nut grass and pigweed a arcad in August and September. 
Only if the water level rises sufficiently to flood this area will the 
excelient food become available to waterf 
Anderson Lake, Astoria.--In this lake, there was very little 
change in the aquatic plants between 1938 and 1939. Marsh smartweed 
was the most abundant specics, American lotus second and coontail 
third. 
Ingraham and Crane Lakes, Snicarte.--American lotus on- 
croached upon the oven waver areca of both lakes in 1939. In Ingraham 
Lake, lotus covered about 85 per cent of the are@. Sago pondweed 
and long-leaved pondweed, scarce in Crane Lake in 1938, were almost 
wanting in 1959. 
Cuba Island, Chandlerville.--This area, because of small 
levee districts holding water, had in 1938 and 1939 an excellent 
growth of good duck food plants. In both years marsh smartweed was 
the most abundant of these food species. In 1959 it was somewhat 
less abundant than in 1938. Saw grass was second in abundance and 
eovered an equal area in both years. Ameri tus increased 
Silachtiy in 1959 over 1958.
