Elwah steelhead success story
More good news from the Elwah River... An article in Northwest Sportsman reveals the incredible resilience of the steelhead which have rebounded faster than predicted following the removal of two dams on the Elwah River in Washington State. The video, "Rising from the Ashes" tells the story from the perspective of the dedicated biologists and volunteers who have undertaken annual snorkel surveys on the remote and hard to access river in the wilderness of the Olympic National Park.
The rapid recovery of the summer steelhead on the Elwah demonstrate the value of resident rainbow trout above dams. Given the chance, even after 100 years with no possibility of returning from the ocean, these fish can make a comeback.
This is real world confirmation of the hope for recovering the endangered southern steelhead populations blocked by Matilija Dam. With no human intervention, other than just getting out of the way, we can realize a rapid recovery of the native fish and the ecosystem on which we all rely.

Ecosystem flows
Natural flows in rivers throughout the American West have been significantly disrupted by dams and diversions, groundwater extraction, land use changes, and other human influences. Over time this has led to the decline of freshwater ecosystems to the point that many species have become endangered. For instance, rivers rely on natural floods for maintenance of the river channel and floodplain, and flow of critical nutrients and biota. Large dams mute or eliminate downstream flooding (winter flood pulses) by capturing these flows in a reservoir. Similarly most western rivers are drying up during the dry months (summer/early fall base flows), an increasing concern with more frequent drought and heat due to climate change, and the primary concern on the Ventura River.

| Functional Flows, figure from "A Path Forward for California's Fresh Water Ecosystems", PPIC 2019 |
The diagram shown here illustrates alterations to the natural flow regime throughout the year and a proposed "Functional flow regime." The aim of functional flows is to re-establish some of the basic river functions in highly modified systems to restore ecosystem function.
The question is how to develop a management paradigm to allocate water to functional flows and ecosystem health?
A recent report by the Public Policy Institute of California presents the case for Ecosystem Based Management as a solution to California's water problems. Maven's Notebook presents an excellent summary of recent discussions along with the technical references.
In particular, this report concludes that the current management focus on endangered species is failing, and we need a more holistic approach:
Ecosystem-based management emphasizes the simultaneous management of water, land, and species to improve ecosystem condition for native biodiversity and human uses. It shifts the management emphasis to the social, economic, and environmental benefits that come from healthy ecosystems, rather than narrowly focusing on mitigating harm to protected species.
Sustainable watershed management plans, backed by binding comprehensive agreements, are the best way to accomplish ecosystem-based management. These agreements can be adopted by state and federal regulators to meet Clean Water Act and ESA requirements and can align other agency priorities and actions.
With ecosystem-based management, there are a suite of actions available. The first is to establish an ecosystem water budget that is an allocation of water for the environment that functions much like a senior water right that can store, trade, and flexibly allocate that water to respond to changing conditions.
An outline of this management approach is presented in the PPIC Policy Recommendations:
Promote inclusive planning and governance
It is important to highlight the differences between ecosystem-based management and other, often similar approaches. For example,
* ecosystem management seeks to manage the ecosystem for species conservation goals and objectives, such as resilient populations of native plants and animals. This is accomplished principally by constraining land and water use and often uses recovery of protected species as a primary objective. In contrast,
* ecosystem-based management integrates human uses into the setting of conservation goals and objectives, balancing the uses of the resource. Ecosystem-based management also differs from
* Integrated Water Resources Management (IWRM), which focuses principally on coordination and funding of local water management projects while managing their impacts on ecosystems.
Renewed discussion of Ecosystem-based Management supports the vision presented in the Ventura River Ecosystem blog. This approach applies readily to the Ventura River Watershed, especially with ongoing planning for this priority basin under SGMA. The Sustainable Groundwater Management Act provides for self-organized groundwater sustainability agencies (GSAs) and required groundwater sustainability plans. However, in our case the Ventura River would ideally combine the two existing GSA's into a single watershed-based agency to better realize the Ecosystem-based management approach.

March rains
| March storm moves over the Ojai Valley. This thunderstorm produced a brief period of hail. |
After, a record dry January and February, the rains returned in March. Perhaps not the "March miracle" of the past, but certainly appreciated given the potential for an otherwise very dry year. At 13" for the season, Ojai is still way below the 23" average rainfall, but it looks like a wet spring ahead.
![]() |
| 28 day Rainfall Map, March 2020 |
The storm of March 11 delivered almost 5 inches at Old Man Mountain, which typically registers the highest rainfall in the region. Old Man Mountain lies at the headwaters of Matilija Creek, resulting in quickly rising waters during a downpour.

| 24 hour rainfall, March 16, 2020 |
The hydrograph below shows flows in the river for the month of March at Matilija Creek and Foster Park. The March 16th rain event resulted in peak flows for the season.
| Ventura River above Hwy 150, 5pm March 16, 2020 |
| Ventura River at Santa Ana bridge, 6pm March 16, 2020 |
This short burst of energy in the river moved significant amounts of sand and gravel sized sediment downstream. In addition to visible deposition in Matilija reservoir, sedimentation was evident at Robles diversion and the reach downstream in the Ventura River Preserve. Gravel is an important habitat consideration for the endangered steelhead, which lay eggs in "redds", or pockets formed in the gravel. The effects of the Thomas Fire continue to be evident as the river transports sediment eroded from the mountains downstream, to the benefit of riverine habitat.

The hydrograph below shows the flows recorded at USGS gages just below Matilija Dam (red line 11114495) and downstream at Foster Park (green line 11118500). The difference between these lines is approximately what is diverted into Lake Casitas (excepting other inflow from North Fork Matilija Creek.)
Note the small peak at Foster Park on March 19 when the operation of Robles diversion was temporarily interrupted for maintenance, perhaps due to the influx of sand and gravel moving downstream.

Lower Ventura River - a decade of cleanup
Almost a decade after the initial cleanup in the lower Ventura River, nonprofits and volunteers continue to take on the endless role as "Trash man" to those who leave their waste in the river bottom.
This video illustrates the dirty job undertaken by Dan Hulst, Preserve Director with the Ventura Land Trust. It is still a full time job...
Looking back to 2011, Santa Barbara Channelkeeper, seeking to bring attention to a growing problem, performed surveys of the area and estimated over 200 people living in the river bottom with no trash or sanitary facilities. The sheer volume of toxic and human waste poised to flush into the ocean was overwhelming.
In 2012, the Ventura Hillsides Conservancy, now Ventura Land Trust, acquired the property downstream of the Main Street bridge. Working through a process set up through a Trash TMDL, local authorities served eviction notices to the camps, and the Conservancy was able to come in and clean up the mess.
Eviction Day (2012) from Matt Linkin on Vimeo.
Ventura Land Trust continues to monitor and maintain the area, working with law enforcement and organizing volunteer workdays to clean up the never-ending mess. A long term solution has yet to be developed, but social service agencies and nonprofits continue to make progress on improving access to shelters and transitional housing for those who desire.

Matilija Dam meetings February 2020
On February 11, 2020 two meetings were held to update stakeholders on progress being made on the Matilija Dam Ecosystem Restoration Project. Technical studies have been underway since 2018 with support from a $3.3 million grant from the California Department of Fish and Wildlife.
As the earlier studies suggest, removal of the dam and release of the impounded sediment has implications for much of the infrastructure downstream including bridges, levels, and water supply components. The current work has been focused on the feasibility of the new dam removal method, analyzing the sediment transport, and re-evaluating the downstream infrastructure needs.
The Technical Stakeholder Group met from 12:30 pm to 4:30 pm at Ventura County's Saticoy Operations Yard. The agenda was filled with technical presentations from the project consultants:
1. Welcome and Introductions – WPD – Peter Sheydayi
2. Dam Removal Contract - AECOM and Stillwater Sciences
a. Field Investigations
b. Dam Structural Evaluations

Ventura River Adjudication – Remembering the Past
![]() |
| Mission San Buenaventura founded March 31, 1782 water supply through aqueduct from the Ventura River at what is now Foster Park |
The City of Ventura was incorporated in 1886, but it claim to the waters of the Ventura River extend back to the establishment of Mission San Buenaventura in 1782. In addition to the Missions, the Spanish and Mexican governments also established a series of Pueblos and Ranchos between 1769 and 1835 in what later became the state of California. Despite its not being a successor to one of the eight original Spanish or Mexican Pueblos, the City has periodically asserted its claim to the waters of the Ventura River based on a Pueblo water right.
In 1976 the City of Ventura attempted to assert a Pueblo water right against the Casitas Municipal Water District. The appropriative water rights granted to Casitas in the 1950’s required them to bypass the first 20 cubic feet per second of flow at the Robles Diversion to protect downstream water rights. The City claimed, however, that this provision did not fully protect its Pueblo water rights.
Conjunctive Use
![]() |
| Ojai Valley News, Feb 18, 1979 |
In 1978, the Friends of the Ventura River filed a lawsuit challenging the Environmental Impact Report’s conclusion that the Conjunctive Use Agreement would not adversely affect the Ventura River. In 1984, after losing in the lower courts, the California Supreme Court rejected the City’s appeal, effectively terminating the Conjunctive Use Agreement.
Endangered Species and Clean Water
In 1997, the National Marine Fisheries Service (NMFS) listed steelhead trout in southern California as an endangered species. Rather than comply with new regulatory requirements, the City decided to forego surface diversion and instead rely on its wells at Foster Park.
In 1998, the State of California formally recognized that the Ventura River was impaired by excessive pumping and diversions pursuant to the federal Clean Water Act.
In 2003 NMFS sent a letter notifying the City that the continued operation of the Foster Park wells posed a serious threat to steelhead. In 2007 NMFS issued a “draft jeopardy biological opinion” that specified a minimum flow to protect steelhead at Foster Park. In response, the City chose to postpone repairs and enlargement of its well field, and recommenced the operation of its other existing wells in the Foster Park area.
A Dry River
In 2013, the City’s hydrology consultants concluded that their pumping was detrimental to critical habitat for endangered steelhead in the Ventura River. The City continued to pump unabated, and from 2014 to 2016 the Ventura River was pumped completely dry at Foster Park for a significant portion of the year.
In 2014, after many years of monitoring water quality in the Ventura River under a program certified by the State, Santa Barbara Channelkeeper filed a lawsuit asking the State to compel the City to reduce its pumping at Foster Park consistent with NMFS requirements. The City responded by petitioning to have the lawsuit dismissed and also simultaneously filed cross-complaints against all other water right holders in the watershed. The Court rejected the City’s petition.
In 2018, the Appellate Court allowed the City’s cross-complaint against all water right holders to proceed. In 2019, the City signed an interim agreement with Santa Barbara Channelkeeper, based on the NMFS 2007 jeopardy biological opinion, and entered into a court-sponsored settlement agreement process with major water purveyors and several major agricultural landowners.
Adjudication

In January 2020, the City of Ventura commenced adjudication by serving legal summons to over 10,000 individual water rights holders in the Ventura River watershed.
(note: Adjudication is just a fancy word for suing everybody in the basin, and to resolve groundwater rights, you have to bring in all the users.)
Ventura Assistant City Manager, Akbar Alikhan, responding to questions about the Ventura River adjudication, claimed “…this is not a water grab. We are trying to find a solution that balances the needs of the local habitat while still providing the valuable water to our local residences.”
Given the City’s long history of claiming unlimited, and unrestricted rights to the waters of the Ventura River, is it reasonable to ask what that balance will be?
Residents who use the watershed, whether as water supply or outdoor recreation, have a stake in the outcome of this latest chapter in the long history of exploitation of the Ventura River.
