Our Limnology Program focuses on the study and conservation of freshwater ecosystems, specifically rivers and streams. Through a range of projects, we conduct comprehensive habitat typing surveys to assess the ecological characteristics and biodiversity of these aquatic environments. Additionally, we implement innovative initiatives such as large-woody complexity installation, boulder weir installation, and off-channel pond creation to enhance habitat diversity and provide refuge for aquatic species. By combining scientific research, data analysis, and collaborative efforts with local stakeholders, our program strives to protect and restore the health of freshwater ecosystems, ensuring the long-term sustainability of these vital natural resources.


Off-channel Ponds: The purpose of Off-channel ponds is to provide thermal refugial habitat for summer rearing and velocity refugial habitat for over-wintering such that the capacity and productivity of tributary habitat is increased.

Large Woody Complexity: Projects are designed to mimic natural stream conditions that produce shelter for rearing salmonids through the use of locally sourced tree trunks, root-wads and brush bundles.

Fish passage improvement: Projects include improvements to road crossings through the installation of a rock ford and improvements to diversions structures through the installation of a series of boulder weirs.
