| Abstract: | The U.S. Army Corps of Engineers, Baltimore District, has been conducting biological surveys of the
inflow and outflow streams of Almond Lake since the early 1980?s. These surveys are made to identify
possible detrimental effects as well as benefits of the reservoir and to better understand the aquatic
communities in the vicinity of the lake at the present and over time. The U.S. Army Corps of Engineers
and the U.S. Geological Survey jointly conducted a survey of the fish communities upstream and
downstream of the lake in Canacadea Creek in September 2000. The fish communities upstream and
downstream were compared and any differences or similarities seen in the communities were noted.
This study found the fish communities to be in fair condition upstream and good condition
downstream of Almond Lake, with Index of Biotic Integrity (IBI) scores of 3.5 and 5.0, respectively. The
habitat conditions of both reaches were of suboptimal quality, with a score of 14 upstream and
15 downstream as determined by use of the U.S. Environmental Protection Agency?s (USEPA) Rapid
Bioassessment Protocols, and are capable of supporting fish communities. The Shannon Index indicates
species richness and evenness and was 1.87 upstream and 3.22 downstream of the lake, indicating the
upstream reach is severely impacted and the downstream reach appears to be not impacted. The Jaccards
Coefficient and the Index of Similarity statistically show these communities are similar with scores of 0.55
and 0.71, respectively. Of the 12 species captured upstream, 11 of those also were captured downstream
along with 8 other species for a total of 19 species downstream. |
