1 + Swirling in Sediment and Slowing Fisheries Recovery A Concurrent Session at the 35 th Annual Salmonid Restoration Conference held in Davis, CA from March 29 April 1, 2017.

2 + Session Overview Session Coordinator: Brain Cluer, Ph.D. and Michael Pollock, Ph.D. NOAA Fisheries

3 + Presentations (Slide 4) Clear and Simple Connections Between Dirt, Fish, Entrenchment, and Recovery Mike Napolitano, San Francisco Bay Water Quality Control Board (Slide 21) Sediment for Salmon in San Francisco Bay: What s Needed, What s Available, and What s Next? Scott Dusterhoff, San Francisco Estuary Institute (Not provided) Mechanical Scarification of Gravel Beds to Increase Chinook Salmon Spawning Success Field Experience in Lower Putah Creek Ken W. Davis, Wildlife Survey & Photo Service

5 Cuyahoga River on fire: Clean Water Act to the rescue Swimmable, fishable, and drinkable

6 Congressional compromise adds obscure provision (Section 303d) to Clean Water Act Early 1970s early 1990s: $$$public funds for sewage 303(d): not swimmable, fishable, and drinkable after treating sewage and cleaning up factory waste, list as impaired Hire a lawyer, go to court & win: EPA goes 0 for 28 Late 1990s: EPA gets religion, impaired waters list has consequences, TMDL program is born

7 Clean Water Act: Pollution and Pollutants Pollutant = substance added by humans or human activities pollution = man-induced alteration of chemical, physical, or biological integrity of water Sediment is a natural and essential element that shapes and maintains stream habitat. Sediment impairment results when human action adversely alter sediment delivery, transport, or storage process, and related habitat structure.

8 Sediment Impaired Streams in the Bay Area Sonoma Petaluma Fundamental alteration of sediment delivery, transport, and storage Eight watersheds:1100 mi 2 25% of Bay Area region San Gregorio

9 Walk through the Napa River watershed today 55 miles of river Regionally significant steelhead and salmon runs Exceptionally diverse native fish assemblage Pacific lamprey Photo credit: Dan Worth Tule perch Photo credit: Dave Giordono Hardhead Photo credit: Lisa C Thompson

10 Sediment is being evacuated from the valleys and from the hollows located in uplands Source: Church (2002)

11 Channels begin on hillslopes in hollows Source: Dunne and Dietrich (1993)

12 Land-uses interact with geology to cause/contribute to evacuation of sediment from hollows Napa River watershed, Carneros Region

13 Soft Sedimentary Type Concentrated runoff Potential for significant reaction

14 Narrow, deep and simple Increases in runoff (examples) Intensive grazing, logging old-growth redwoods, Direct channel disturbances LWD jam removal, Connecting naturally disconnected tributaries, straightening Channel reaches, levees, bank stabilization Decreases in supply of gravel and coarser Gravel mining at rates higher than replenishment, Dam construction, dredging

15 Deeply incised: alternating between bar-pool and plane-bed Lower Carneros Creek, tributary to Napa River Photo credit: California Land Stewardship Institute (2011)

16 Fallen trees and bank erosion are agents of restoration

17 Big changes in channels over short distances Scale: upstream to downstream = about 1 mile A B Rutherford Reach of Napa River

18 A Complex channel reaches: Bar-pool topography Connected floodplain Diverse/extensive riparian B Bowling alley reaches: Lake-like pools dominate Deep, narrow, disconnected Simple/narrow riparian

19 Restoration tool kit Channel Restoration Active reach-scale channel reconstruction Jump starting LWD recruitment Constructing natural LWD jams Passive restoration by bank erosion & natural LWD recruitment Baseflow protection and enhancement Real-time dial-up gages to aid avoid dewatering Conversion to wet season off channel diversion/storage Enhanced infiltration in farms and rangelands Developing treated wastewater to reduce diversion and pumping

20 How to get more done More creative approaches to regulation water rights reform water quality attainment strategies watershed permits Much more public education/outreach Napa Living River and Wildcat Creek examples Much greater funding AB 32 offsets (carbon farming, floodplain restoration) Napa County Measure A example Bay Area Measure AA WE HAVE TO BECOME RESTORATION ADVOCATES

32 Where will we get the sediment needed to restore baylands? Where will we get the sediment needed to sustain baylands?

33 Flood Control Channels Vital Sediment Source Sediment Accumulation in Lower Novato Creek Dredged Sediment Deposit next to Lower Walnut Creek

34 Flood Control Channels Vital Sediment Source Key management questions regarding sediment supply How much watershed sediment enters flood control channels? How variable is the watershed sediment supply? How much sediment is removed and at what frequency? Where along the major flood control channels is sediment being stored and removed?
