Matilija Reservoir March 2020

Matilija Reservoir March 17, 2020
It appears that our March rainfall event moved more sediment into Matilija reservoir.   Flows in the upstream delta are currently split so that the remnant reservoir has two inlets, one on each bank.  Last year saw significant deposits at the right bank (background of this photo.)  Here, new deposits are visible on the left bank (in the foreground of the photo).

Matilija Reservoir March 21, 2020
By March 21, the reservoir elevation had been lowered due to Casitas Municipal Water District's operations to release water from Matilija reservoir for downstream diversion at Robles.  This revealed the extent of the sedimentation, and allowed the inlet flows to erode a channel.  Note that although the creek was flowing clear, the reservoir still had suspended sediment lingering from earlier in the week.

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.

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.

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
      c. Sediment and Hydraulic Analysis
      d. Predictability of Flushing Event
      e. Re-evaluation of downstream Project Components and Real Estate Plan
      f. Short-term Water Supply Mitigation Alternatives Refinement
      g. Long-term Water Supply Mitigation Alternatives Refinement (Robles)
3. Santa Ana Bridge – WPD
4. Camino Cielo Bridge – Dokken
5. Levees (Casitas Springs, Live Oak Acres, Meiners Oaks) – Tetra Tech
6. Coastal Sediment Studies – Integral
7. CEQA Update and Permit Plan – Aspen
8. Project Schedule and Upcoming Grants – WPD
9. Closing – WPD (5 min) – Peter Sheydayi

The evening Community Stakeholder Update meeting  was held from 6:00 pm – 8:30 pm at the Oak View Park and Resource Center Auditorium.

1.    Welcome and Introductions – Andrew Spyrka (VCRCD), Glenn Shephard (VCWPD)
2.    Project Overview – Peter Sheydayi (VCWPD), Paul Jenkin (Surfrider Foundation)
3.    Funding Updates – Hans Cole (Patagonia, Inc.), David Yardas (Project Consultant)
4.    Organizational Updates  – Sam Jenniches (State Coastal Conservancy)
5.    Technical Updates  – Peter Sheydayi, Brian Person (AECOM)
6.    Project Schedule – Peter Sheydayi
7.    Questions and Discussion – Public and Presenters
8.    Closing  – Glenn Shephard, Andrew Spyrka

In case you missed it, the evening meeting was recorded and up on the Ventura River Watershed Council's YouTube channel:

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 current controversy surrounding the adjudication of water rights to the Ventura River has focused on the most recent efforts by the City of Ventura to secure its water rights to the Ventura River.  Many may not know that this effort has deep roots in the past.

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
To resolve this dispute, without formally asserting and establishing the City’s Pueblo water right, the City and Casitas proposed to enter into a Conjunctive Use Agreement. This agreement would have allowed Casitas to divert all of the low flow of the Ventura River at its Robles Diversion (up to 500 cubic feet per second) to Lake Casitas.  In exchange Casitas would guarantee the City up to 6,000 acre-feet of water annually from Lake Casitas.

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.


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.

Ventura Initiates Adjudication

January, 2020 - Over 10,000 residents in the Ventura River watershed were formally served with a legal notice of water rights adjudication.  The City of Ventura initiated this adjudication in response to Santa Barbara ChannelKeeper's legal action to compel the city to leave water in the Ventura River.  Pumping at the City's Foster Park well field has dried up the river for months at a time during the recent drought.  The City's cross complaint contends that upstream pumping and diversion are part of the problem.

This action, taken without any advanced notice, has created confusion and community backlash against the City.

Perhaps most confusing is how this legal action will affect ongoing efforts by local water agencies to comply with the State Groundwater Management Act (SGMA).  This state law was enacted in 2014 to develop sustainable management of groundwater basins throughout California.

"the SGMA process offers a lot of promise in bringing local groups together to devise groundwater management solutions that are tailored to local conditions.  When stakeholders come together and agree, they have good leadership, then the path forward is going to be a lot smoother.  

... the Las Posas and City of Ventura adjudications will be the first under the new law, so it will be interesting to see how these cases lay the foundation for how the SGMA process in these streamlined adjudications will play out on the ground.  

Even with the new legislation, adjudications are going to remain expensive, time consuming, and take a lot of resources... advancing the SGMA process, if people can’t come together to come to an agreement, there are probably ways to use those streamlined adjudications to establish clear deadlines in how to move forward while also creating certainty around pumping rights."
