WELCOME TO MTFFMTFF is a fly fishing club in Marin County, CA. Since 2004, we have been bringing together fly anglers to share knowledge, experience, and good times. We host monthly meetings, fishing trips, casting clinics, and social dinners and events. Our members span all skill levels from beginner to veteran. We offer membership to anyone interested in fly fishing regardless of the skill level. Prospective members are welcome to attend our monthly meetings, meet current members, and learn more about us. If you would like more information please email info@mttamflyfishers.org. | Upcoming events

MARCH 28--Jacob Katz, CAL TROUT Senior Scientist
Zoom at 7:00PM
Featuring Cal Trout's efforts working with fish,water and people to help maintain California's diverse fish populations.
Jacob will briefly overview Cal Trout overall and also dig in to some of the cool work he leads in the Central Valley with fish, floodplains, farms and waterfowl.
"Puddle Power and the Pivot to Process: A Landscape-scale Recipe to Allow California River Valleys to Make Salmon Again."
Jacob Katz, PhD, California Trout
Central Valley native fish stocks continue to slide towards extinction despite decades of conservation effort and billions of dollars of investment leading many to believe that endangered fish populations may be an inevitable consequence of human development. This presentation will summarize a decade of work unequivocally demonstrating that collapsing aquatic ecosystems and endangered fish populations are, in fact, a direct result of infrastructure and land use practices but into effect long before we understood how they interrupted natural river valley processes and ecosystem functions.
We will focus on the hydrologic conditions typifying ephemerally inundated floodplains—shallowe depths, warmer water, longer water residence times and predominantly detrital carbon sources compared to deeper, colder, swifter water and a predominantly algal-based carbon source in adjacent river channels—which appear to facilitate the dramatically higher rates of food web and salmonid biomass production observed in off-channel habitats compared to stream channels.
The Sacramento Valley has been highly altered, resulting in loss of hydrologic connectivity between river and formerly inundated floodplains and degraded fish habitat quality in two major ways:
1. Levee construction reduced fish access to floodplainLevee construction during the late 19th and early 20th century reduced the frequency of hydrologic connection between river and floodplain by ~95%.
2. Pervasive landscape-scale alteration to wetland topography severely degraded floodplain habitat quality
Prior to levee construction Sac Valley floodplains regularly flooded for months at a time. In the few places where floodplains still regularly inundate, such as Sutter and Yolo Bypasses, wetland land surfaces have been extensively graded to expedite drainage of floodwaters. By their very design the bypasses expedite the drainage of wetlands and limit inundation duration and short circuit the aquatic food webs which once fueled fish abundance.
This talk will outline a portfolio of solutions that reimagine water infrastructure and operation in ways that reactivate natural floodplain functions at the landscape scale needed to elicit population level response and set native fish populations on a trajectory towards recovery.
In the meantime, read about Cal Trout's work on a Marin County Jewel
