TAYLOR LAKEpH LEVELSTAYLOR LAKE - MAIN BASIN2012 pH LEVELSHelp MVCA and theOntario Federation of Anglers and HuntersStop the Invasion!Taylor Lake was tested for invasive species, particularly zebramussels, spiny water flea, and rusty crayfish, in partnership with theOntario Federation of Anglers and Hunters (OFAH). In 2012, zebramussels, spiny water flea and rusty crayfish were not present in thesamples collected.Residents and property owners need to ensure that all access pointsto the lake have posted signs indicating the precautions thatboaters and anglers can take to prevent the spread of invasivespecies into Taylor Lake. Residents are also invited to participate inthe Invading Species Awareness Program(www.invadingspecies.com) through MVCA and OFAH.The plankton haul net (pictured above) looks like a wind sock with a plastic cup attached to the end. The mesh size of thenet is 63 microns, which can filter microscopic organisms (plankton) like spiny water flea and zebra mussel veligers fromthe water. The plastic cup portion of the net is called the cod end. It collects the plankton sample as water passes throughthe net.Check and clean watercraftevery time it is moved to adifferent water body!Baited minnow traps (pictured right) with slightly widenedopenings on each end are used to sample for rusty crayfish.Traps are placed in shallow areas along the shoreline. Traps areleft for a minimum of 24 hours. If crayfish are found in thesample, MVC staff identify the species and release nativecrayfish back into the lake.8

Benson, USGeological Survey.TAYLOR LAKE SAMPLING RESULTS—MAIN BASINDissolved Oxygen (DO) is adissolved form of oxygen vital for allunderwater plants and animals tosurvive; it's what they need to breath.Adequate dissolved oxygen isimportant for good water quality andnecessary to all forms of life. Poor(low) DO levels will cause stress onfish and may result in fish kills (massdeath of a species in a season).MVCA takes three DO readings eachsample season. By monitoring the DOlevels of our lakes we can developlake profiles showing the lakestratification and the state of the lake.Lake Stratification is the separationof lakes into three layers:The Dissolved Oxygen Metre is used to gather DOand temperature readings. The probe is loweredinto the lake and readings are taken at every metrefrom the hand-held screen.STATE OF THE LAKE REPORT 2012 9
