Opportunity Summary:
The grant opportunity titled "Use and Importance of Tributaries to Sustain Native Fish Communities in the San Juan River" is a Bureau of Reclamation (Upper Colorado Region) cooperative agreement aimed at improving how managers understand and protect native fish in the San Juan River system. The central idea is that tributaries may play an outsized role in keeping native fish populations viable, either by providing better habitat conditions than the mainstem at certain times of year, serving as spawning or nursery areas, or functioning as seasonal refuges when the main river becomes too warm, turbid, or otherwise stressful. At the same time, tributaries can also act as pathways or source areas for nonnative fish that compete with, prey on, or otherwise harm native species, so the work is designed to capture both the benefits and risks that tributaries present.
The proposed project focuses on seasonal surveys of major San Juan River tributaries, with sampling reaches spread along longitudinal gradients in three main tributaries. This spatial design is meant to detect how fish communities and habitat conditions change from lower tributary areas near the mainstem connection up to higher reaches, and to evaluate how much exchange occurs between tributary habitats and the main river. The work is organized around four research objectives. First, the project will document fish community composition in tributaries and track how those communities vary over space and time, which helps identify where native species are persisting, where nonnatives are concentrated, and whether community structure shifts seasonally or between years. Second, the project will describe key habitat conditions in each tributary, including flow statistics, temperature, turbidity, overhead cover, and channel dimensions such as width and depth. These measurements are intended to connect biological patterns to physical drivers, for example whether natives are associated with cooler temperatures, particular flow regimes, or specific habitat complexity that may differ from nonnative preferences. Third, the project will assess whether fish movements into, out of, and within tributaries are linked to environmental conditions (like temperature and flow) and to species reproductive ecology, which addresses questions such as whether fish move into tributaries during spawning periods, during high-flow events, or when mainstem conditions deteriorate. Fourth, the project will identify potential barriers to fish movement within tributaries, which could include natural features or human-made structures that prevent fish from reaching critical habitats, fragment populations, or alter access to seasonal refuges.
Field methods combine standard fish sampling and habitat monitoring with individual fish tagging to directly measure movement. Fish population densities will be estimated using backpack electrofishing gear and seines, which are commonly used for wadeable tributary environments and allow consistent seasonal comparisons among sites. Habitat measurements will be collected at each sampling reach to test which habitat features are favored by native versus nonnative fishes. A major component of the study is marking fish 150 mm and larger with passive integrated transponder (PIT) tags. PIT tags allow researchers to identify individual fish over time and document where and when they move, providing stronger evidence than snapshot surveys alone. By tracking tagged fish, the project can quantify seasonal tributary use, detect connectivity with the mainstem, and evaluate whether movement patterns align with changing environmental conditions or life-history events such as reproduction.
A key feature of the proposal is coordination with existing monitoring programs on the mainstem San Juan River and with tagging studies run by the Colorado Division of Wildlife (CDOW). Because these programs already have the capacity to tag and scan fish, the tributary work can be leveraged to improve understanding of dispersal between tributaries and mainstem reaches. This kind of integration matters because tributary findings become more actionable when they can be linked to broader mainstem population trends, rather than remaining isolated to small subwatersheds.
From a management perspective, the project is framed as producing information that can directly guide decisions in the San Juan River system. One expected outcome is an updated picture of the status of native fishes in tributary habitats, including species that may have declined substantially in the mainstem. The opportunity specifically highlights roundtail chub (Gila robusta), noting it has virtually disappeared from mainstem habitats and that tributaries might be especially important for its persistence. The work is also relevant to recovering populations of federally listed species, where identifying essential seasonal habitats and movement corridors can shape conservation priorities. Another intended outcome is a clearer understanding of how tributaries are used seasonally and whether periodic access to tributary habitats could help bolster mainstem native populations. At the same time, the project will evaluate whether tributaries are acting as sources of nonnative fish that negatively interact with natives, information that can influence targeted removal, barrier management, or habitat modifications. Finally, by explicitly assessing barriers to movement, the study can inform whether restoring connectivity (or in some cases maintaining selective barriers to limit nonnative spread) would benefit native fish conservation.
Administratively, this was a continuation opportunity offered as a cooperative agreement under CFDA 15.517 (Fish and Wildlife Coordination Act). The Bureau of Reclamation anticipated a single award with total funding of $118,296, with the award floor and ceiling both set at $118,296 and no cost sharing or matching requirement. The opportunity was posted on September 7, 2012, with a closing date of September 20, 2012, and it was archived on September 21, 2012. Eligible applicants were broadly described to include governmental entities, nonprofit and other institutions, tribal governments and Native American organizations, individuals, and private-sector organizations, though the listing of eligible categories in the source information emphasizes Native American tribal organizations (other than federally recognized tribal governments) and state governments. The sponsoring agency is the Bureau of Reclamation, Upper Colorado Region, and the point of contact listed for access issues was Timothy Wagoner, Grants Management Specialist (801-524-3704).
