‘First Flush’ Water Quality Monitoring Results Are In

The storm that swept through Nevada County between the 23rd and 25th of October dropped between seven and twelve inches of much needed precipitation. This rainfall has led to, among other things, increased flows in the Yuba River and SYRCL’s ‘first flush’ event.

We sat down with our resident hydrologist, Karl Ronning, to learn more about this ‘first flush’ event and to discuss the results of our water quality monitoring.

Recent Rain Tests Hallwood Restoration Project

The storm that swept through Nevada County between the 23rd and 25th of October dropped between seven and twelve inches of much needed precipitation. This rainfall has led to, among other things, increased flows in the Yuba River. 

We sat down with one of our SYRCL scientists to learn more about how this rain event interacted with the Hallwood Side Channel and Floodplain Restoration Project, a restoration effort that SYRCL has been working on and committed to for the past five years.

Update on Centennial Dam

Nevada Irrigation District is re-engaging in an effort to plan for their future water needs. The resulting plan will be known as the Plan for Water and the public process kicks off on November 9th at 4PM. The final version of the plan will reassess hydrology, water supply, and demand over the next 50 years. Ultimately, the plan will help NID determine if our region needs additional water storage. Thus, this planning process will be an important inflection point in the campaign against Centennial Dam.

SYRCL’s Salmon Expeditions Serve More Students

Earlier this month, we resumed Salmon Expeditions for grade school students from Nevada and Yuba counties after a year away from the river.

SYRCL has worked with schools to implement COVID-safety precautions so the organization can float nearly 1,200 students down the lower Yuba River on rafts to witness spawning salmon. Thanks to a generous grant from Yuba Water Agency, students from Title 1 schools in Yuba County are able to attend free of charge.

Signs of Spring at Hallwood: Restoration Update

With more than 1.2 million cubic yards of goldrush-era mining sediment removed, historic floodplain habitat has been exposed for Chinook salmon, steelhead, and sturgeon. Today, miles of seasonal and perennial side channel habitats were carefully engineered to provide additional rearing habitat for native salmonids like Chinook salmon. Details
