Lily Pond

Lily Pond
Location: Just north of Buchanan and West of Timberlane
Size: ~2 Acres (No GPS Map)
Inlet/Outlet: Inlet pump with no outlet
Developed Shoreline: Some development on the West side with preexisting houses to the NE. High bank is unstable and erosion is a major threat
Max Depth: ~10 ft
Mean Depth: ~6ft
Aquatic Vegetation/Macro Algae: Being among the youngest of the CLPOC lakes, Lily Pond is one of the least diverse systems in the development. The pond bottom is colonized by Chara; with no other aquatic vegetation being observed. This leaves the pond extremely susceptible to algal blooms as there is no native vegetation to take up nutrient inputs from erosion and terrestrial debris inputs.
Fish Population: The Lily fish population is highly artificial, unstable, and biologically inappropriate from a recent pre-CLAM stocking. The stocking of Hybrid sunfish, Largemouth Bass, and Channel Catfish will make it next to impossible to establish a forage base of minnows. A small school of minnows was observed on the day of assessment. It is likely these forage fish will be exhausted by bass predation after young of year bass and bluegills have all been consumed. Prey has no cover and low quality food. Spawning beds were common but no young of the year fish were observed due to extreme predation and cannibalism.
Plankton Data: 7-20-2005
No herbicide treatment in 2005
The Inlet Pump was running at time of sampling
Zooplankton: Rotifers, Copepods (dominant) and Cladocerans present
Phytoplankton: Dominated by small filamentous Ulothrix-like, some Spirogyra.
Asterionella most common plankton smaller green algae rare, sample not very diverse
Notes: On the day of the assessment, numerous geese were on the pond. Abundant painted turtle and various frogs also observed. Algal blooms will continue to be an issue having no real native vegetation to take up released nutrients. The inlet pump is low in nutrients and should help to maintain water quality.
Recommendations: Establish non-nuisance native plant population. No fish stocking until present population stabilizes and aquatic plants take. Focus attention on the high banks erosion to get them stabilized as soon as possible.
