Canadian baseline monitoring shows healthy Horse Creek
Baseline monitoring conducted by the Little Creeks and Rough Fescue Appreciation Society showed that Alberta’s Horse Creek is healthy but still threatened, according to a Rocky View Weekly article. 
 The initiation of the study was one of the main goals of the nature loving group of Canadian women. It is now in its second year. 
 They collected funds to hire a consultant to monitor the creek. Parameters such as temperature, dissolved oxygen, pH, conductivity, dissolved and suspended solids were measured. The study also examined nutrient intake into the creek. 
Monitoring showed the creek was in relatively good health but is threatened by excessive water flows from nearby Cochran Lake, nutrient loading and inflow of higher conductivity water.

California Polytechnic State University, San Luis Obispo (Cal Poly, SLO), has been monitoring Morro Bay for decades, and while the monitoring program has changed over the years, the dedication to monitoring the bay has remained the same. 
 
The project started in 2006 as a Packard Foundation-funded initiative to monitor water quality flowing in and out of Morro Bay. The goal at the time was to use the data collected to develop and inform an ecosystem-based management plan in collaboration with the Morro Bay National Estuary Program (MBNEP). 
 
Since the estuary was the focus at the time, researchers were monitoring water flowing into the estuary from Chorro Creek and Los Osos Creek.

While the bay of Green Bay has been referred to as the largest freshwater “estuary” in the world, the watershed hosts intensive agriculture and contributes one-third of Lake Michigan’s total phosphorus load. 
 
 The Fox River flows into the bay, carrying excess nutrients largely the result of non-point source runoff from the watershed. With a history of deterioration extending well into the last century, the bay ecosystem suffered significant declines in water quality. 
 
 This, in turn, stimulated major clean-up and ongoing restoration efforts to improve water quality. Tracking these changes is an important aspect of ecosystem management.
