Along California's North Coast, where salmon hover on the cusp of extinction, scientists and local residents seek new collaborations. Agencies, tribes, and watershed councils commission competing studies to determine links between human water use, oceanic cycles, and salmon decline. Modelers turn to ranchers' expert opinions to condition hydrologic models. Ranchers import beavers to build dams that may raise the water table. These watershed collaborations begin to transcend boundaries of human institutions, scientist / lay person, and even species. Restoring salmon-bearing streams is a project to reconfigure human relationships to water and inhabitation practices. In

My dissertation investigates how watershed collaborations transform scientific practices,

environmental subjectivities, and trans-species relations, using Salmon Creek (Sonoma Co., CA) as a

case. Salmon Creek is typical of thousands of small watersheds in the Pacific West in that summer

water extractions by farmers and rural residents dry many tributaries into a series of disconnected

pools. This anthropogenic drought compounds historic beaver removal, logging, and road building

that have altered water, sediment, and large wood supply to the stream, limiting steelhead

(Oncorhynchus mykiss) and coho salmon (O. kisutch) recovery. I argue that collaborative watershed

research that refuses to privilege expert science over local and Indigenous knowledges can create

novel modes of scientific practice, discursive shifts, and new governance approaches. I stretch the

limits of the terms ‘watershed’ and ‘collaboration’ to encompass interactions among (1) scientists

and local knowledge holders, (2) living species and the landscapes they inhabit, and (3) humans and

other species that depend on riverine ecosystems. Though disparate in methodology, the fields

—Science and Technology Studies, Environmental Politics, and Eco-

hydrology—share a commitment to critically re-working social-natural boundaries.

Natural flow regimes—dynamic streamflow patterns that drive riverine biodiversity—arise

from a kind of collaboration between climatic factors, geology, plants, and animals in a river basin,

and are then further shaped by human ground and surface water diversions. Regarding the

ecosystem as a collaboratory in which humans play a role, Quantifying abiotic habitat characteristics

to determine thresholds for salmonid oversummer survival in intermittent streams investigates the

role of different flow-mediated factors (dissolved oxygen, temperature, groundwater inflow, and

pool volume) affect juvenile coho and steelhead occurrence in two Salmon Creek tributaries.

Drawing on three years of juvenile fish surveys, synoptic water and isotope monitoring and

streamflow gauging to populate statistical models, I found that low dissolved oxygen and pool

volume limit survival; however both salmonid species can survive in spring-fed intermittent pools

that contain sheltering logs or overhanging banks. Citizen science surveys of stream drying patterns

and salmon occurrence can complement agency monitoring and should be incorporated into salmon

recovery efforts.

Regarding human collaboratives of knowledge and practice, ‘Thinking with salmon about

rain tanks: stream commons as intra-actions’ puts forth the argument that cultural practices of water

use evolve in response to new understandings of other species' dependence on shared streams.

Some Salmon Creek residents who install rain cisterns to curtail summer water use do so out of

concern for salmon, and describe salmon and other riverine creatures as having rights to enough

water to survive that are of the same status as human rights to water. Other residents are unwilling

to reduce water use because the connection between their wells and the stream are poorly

understood and difficult to measure.

‘Rain tanks, springs, and broken pipes as emerging water

commons along Salmon Creek, CA, USA’

. Residents who participate in monitoring salmon populations, water quality, and their own springs and rain tanks report that these activities have increased their sense of interdependence with other human and nonhuman neighbors

who rely on the watershed’s limited water sources. Drawing on Barad’s (2007) concepts of apparatus and intra-action, I argue that the notion of water as an interspecies commons is co- evolving with rainwater harvesting and that collective choice frameworks that embrace both management practices and environmental imaginaries represent a coherent alternative both to state and market frameworks of water governance and to traditional adaptive management methods and discourses.

approaches to watershed governance.

Salmon Creek is geographically small and removed from major river basins, yet functions as

a kind of microcosm of the political, cultural, and ecological tempests these salmon recovery and

ecological restoration projects stir up at any scale. Salmon are simultaneously a global fishery

resource, a key subsistence and cultural resource for traditional peoples around the Pacific, a

scientific project to avert extinction, and a contested site of knowledge production. In asking what

forms of collaboration are productive, and how collaborations transform those who undertake them,

this research contributes to debates on practice and ethics inherent in environmental governance in

the Anthropocene era.
