      The presence of soluble, sedimentary rocks in the watershed of the Finger Lakes determines the chemical regimes comprising the lakes (Schaffner and Oglesby 1978). As the rest of the Finger Lakes, Honeoye Lake has an abundance of calcium and bicarbonate ions (Schaffner and Oglesby 1978). Nitrate + nitrite values for Honeoye Lake in 1993 (mean = 0.02 mg/L) were significantly lower (P< 0.02) than levels from 1973 (mean = 0.07 mg/L) (Crego 1994). In 1973, Honeoye Lake had the highest total phosphorus (TP) concentration of the eight Finger Lakes examined (21.7 ?g/L, August) (Schaffner and Oglesby 1978). However, there were no significant differences in total phosphorus and soluble reactive phosphorus (SRP) concentrations from 1973 to 1993 (Crego 1984). During the summer, Honeoye Lake’s deepest waters are not completely oxygenated and 5 experience algal blooms that impair water quality (NYSDEC Region 8). Eelgrass, pondweed, Eurasian milfoil, and water stargrass are the predominant rooted aquatic plant species that are found in near shore areas out to a depth of approximately 15 feet (~5m) (NYSDEC Region 8). The large macrophyte community (weeds) and the reoccurring blooms of algae on the lake are in part the driving force of this study. Excess nutrients, especially phosphorus, can be a major cause of an over abundance of macrophytes and algae. One source of nutrients to a lake is losses from watershed. The goal of this study was to document the level of nutrient and soil loss from the watershed into Honeoye Lake.
    • Water Quality Study of the Finger Lakes: Part A: Synoptic Water Quality Investigation

      The purpose of the current study is to conduct such comparative investigations and to assess water quality conditions and trends within the Finger Lakes. The study is composed of two distinct components, Synoptic Water Quality Investigation and Sediment Core Investigation. The Synoptic Water Quality Investigation is designed to assess current limnological conditions, and to evaluate water quality trends within this important set of lakes. This portion of the Study was initiated in 1996 and is continuing at present. The Sediment Core Investigation is designed to assess chemical trends within the Finger Lakes over time. This portion of the Study is designed as a one-time effort, and sample collection occurred between 1997 and 1998.
    • Water Quality Study of the Finger Lakes: Part B: Sediment Core Investigation

      Callinan, Clifford W.; New York State Department of Environmental Conservation (2001-07-01)
      The purpose of the Sediment Core Investigation is to systematically assess chemical patterns within the Finger Lakes over time. Specific goals of the Study are as follows: 1. Assess spatial variations in chemical patterns between the Finger Lakes, 2. Assess temporal patterns of chemical inputs within each lake, 3. Evaluate chemical levels with respect to sediment quality assessment values, 4. Determine sediment accumulation rates. A second, related study, termed the Synoptic Water Quality Investigation, involves long term synoptic water quality monitoring on each of the lakes and is discussed above (see Part A)
