Salmon and steelhead require gravels of a specific size range in order to build their spawning beds. These gravels are essential to the viability of the eggs, offering protection and allowing for oxygenation of the water as it flows through the bed. In the Deer Creek watershed, dams have altered the natural sediment transport and deposition dynamics, which has led to the stretch of Deer Creek downstream of Lake Wildwood being depleted of gravels of suitable size for spawning salmon to use. Adding gravels will replicate the natural process currently interrupted by the dam. Sierra Streams is currently implementing a Supplemental Environmental Project, funded by Nevada County Sanitation District #1 in lieu of fines owed to the Central Valley Regional Water Quality Control Board for violations at the Lake Wildwood Wastewater Treatment plant. The funding has allowed us to complete the lengthy permitting process, and to plan for a pilot gravel augmentation effort scheduled for August 2011. Additional funding is being sought for further gravel injections and to develop an annually repeateable plan to inject gravels harvested from Lake Wildwood during the periodic dewatering: gravels that would naturally be transported to the spawning reach but for the presence of Lake Wildwood dam.
