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.

Microcystin, one of several toxins produced by the cyanobacteria that form harmful algal blooms (HABs), has become a popular topic of lake research as the human health impacts of HABs become better understood. Stone Lab is one of the leading groups in algal bloom research on Lake Erie and other lakes in Ohio. 
 
For more than 100 years, Stone Lab has conducted biology research and provided science education and outreach to the region. Over the years, thousands of individuals of varying ages have learned from the resources Stone Lab provides. 
 
Stone Lab’s Research Coordinator and Senior Researcher, Justin Chaffin, learned of Stone Lab while an undergraduate student at Bowling Green State University Fireland Campus.
Read MoreFrom Assessment to Angler: Continual Research Ensures Lake Erie Remains a Beacon of Freshwater Fishing
Lake Erie is well known for its abundant recreational fishing. Anglers come from across the country to try their luck at the “walleye capital of the world” and search for other freshwater species, such as bass, perch, and steelhead trout. 
 
 As one of the world’s largest freshwater fisheries, much effort is made behind the scenes to maintain fishing opportunities for visitors to enjoy year after year, efforts that often go unnoticed by the public. 
 
 One of the lake's most important economic and tourism centers is the city of Sandusky, home to the Sandusky Fisheries Research Station . As part of the Ohio Division of Wildlife, the unit serves as a base for assessing fish populations and managing harvest with partner agencies from around Lake Erie.
