Volunteers identify the species based on their breeding season call or songs and determine the abundance of each species using a call index of 1 (1-5 individuals), 2 (6-12 individuals) & 3 (unable to count individuals). In the Tri-County area, anuran species include the Wood Frog, Western Chorus Frog, Spring Peeper, Northern Leopard Frog, American Toad, Gray Tree Frog, and Green Frog. Volunteers are unable to observe the other species shown in Figure 3-6 because they are primarily found along the lake shore, in the Upper Peninsula, or their population is declining in Michigan. Volunteers monitored the frogs and toads primarily in Watertown Township and Meridian Township. Approximately 4 sections within the Looking Glass River Watershed were surveyed by 12 volunteers. Tri-County area data from the frog and toad surveys are available from the MDNR going back to 1996.

Water Chemistry From November 18 through November 25, 1994, a study was conducted to assess the chronic toxicity of the Looking Glass River in DeWitt Township. Ceriodaphnia dubia and fathead minnow tests were performed on samples from the river and indicated the river water was not acutely or chronically toxic to either species (Butler 1995). The river water met Michigan Water Quality Standards and therefore the aquatic toxicity requirements. No toxic chemicals were detected at or above the detection limit. A water chemistry study was conducted in July of 1992 indicating that levels of phosphorous and ammonia were slightly elevated but were only a result of above average rainfall prior to sampling. The elevated levels were subsequently of no concern (Scott 1993). See Table 3-7 for a summary of the water chemistry data found during the study.
