Water Quality Monitoring Protocol for Inland Lakes. Great Lakes Inventory and Monitoring Network Version 1.0.

摘要

Inland lakes are important and valuable resources at six of the parks of the Great Lakes Network (Apostle Islands National Lakeshore (APIS), Indiana Dunes National Lakeshore (INDU), Isle Royale National Park (ISRO), Pictured Rocks National Lakeshore (PIRO), Sleeping Bear Dunes National Lakeshore (SLBE), and Voyageurs National Park (VOYA)). The Great Lakes Network (hereafter, GLKN or the Network) parks encompass a variety of aquatic habitats and biota, including 129 named lakes, totaling nearly 41,000 ha (101,000 acres) (Lafrancois and Glase 2005). This protocol addresses monitoring of inland lakes to assess change in basic limnological parameters, including those mandated by the National Park Service (detailed below), for the purpose of tracking changes in water quality over time.
