The Lower Nehalem Watershed Council is excited to host Jeremy Lees on March 18 as he presents Bio-Surveys LLC’s findings from the Lower Nehalem Rapid Bio assessment and Limiting Factors Analysis.

Bio-Surveys LLC conducted a Rapid Bio-Assessment Inventory (RBA) for Salmonoids within the Lower Nehalem watershed during the summers of 2018 and 2019. A total of 202.2 stream miles were snorkeled, encompassing all mainstream and tributary habitats exhibiting anatropous potential from the confluence with the Pacific Ocean to the confluence of Humbug Creek (RM 34.7). The intent of this project was to quantify distribution and relative abundance of all salmonoid species within the range of anadromy during summer pinch period low flow regimes.

Additionally, spawning gravel abundance estimates and anchor site identifications (LFA Lite) were included along with an inventory of thermal refugia within the lower 34.7 miles of the mainstream Nehalem. In this presentation Jeremy will review their findings and discuss the watershed's strengths and challenges.

“The prioritization based on this RBA are central to the LNWC’s current work,” said Zac Mallon, the LNWC’s Coordinator. “It helps us focus our outreach and spending on places where our work can have the most impact.”

Since 2019 the LNWC has implemented large wood placements in two of the prioritized stream segments, has secured funding for two more prioritized segments, and are developing additional projects all based on the RBA.

Jeremy Lees is the owner and operator of Bio-Surveys LLC. Jeremy has been with Biosurveys for 13 years. Over those years he has co-authored several RBA reports, conducted inventories across over 1000 miles of Oregon’s rivers and streams. This experience gives Lees a wealth of direct experience with salmon habitat and directly monitoring the impacts of restoration activities.
