Water and Native Fish In Our Local Watersheds
Happy Holidays!
After a few weeks of beautiful weather—warm days with nary a cloud in the sky—I must say it’s been wonderful to enjoy these days outdoors, even though there hasn’t been steelhead fishing in our local coastal streams. Even though the flows are low, it’s a good thing the fish aren’t pressured (legally, that is) on streams with low flow restrictions. But we do need rain and so do the fish. So, by the time this article gets published, I hope we’ve had a few good storms. What does the have to do with conservation? If you get where I’m going with this, it’s about water. And when it comes to fish, the abundance and quality of water means just about everything. With this in mind, I have some news I’ve come across recently about a water issue related to native fish in our area that is interesting.
Santa Cruz Watersheds
Last September, the Santa Cruz City Council approved the Anadromous Salmonid Habitat Conservation Plan that was a collaborative effort led by the City of Santa Cruz Water Department, with significant contributions from the Coastal Watershed Council, County of Santa Cruz Water Resources, Resource Conservation District of Santa Cruz County, and San Lorenzo Valley Water District. This plan has been in the works for about two decades. Some of the key aspects of the plan are:
Conserve and restore steelhead and coho salmon populations in the project area in Santa Cruz County.
Restore fish habitat. Examples are the placement of logs in San Vicente Creek and removal of invasive plants by the Resource Conservation District of Santa Cruz County.
Increase flows in streams to allow fish safe passage. Under the plan the water department will be allowed to take less water from the San Lorenzo and other area streams. Included in the water diversion plan are limits on the amount that can be drawn based a number of factors that are tied to the flows and the fish life cycles. The plan also calls for the sharing of water between Santa Cruz, Scotts Valley and Soquel Creek water districts. Well and aquifer storage is also part of the plan.
Mitigate negative impact of maintenance and other water department activities on fish.
Repair and improve water diversion infrastructure.
The plan is a thirty year strategy budgeted at $36 million.
There have been some encouraging observations of steelhead and coho in Mill Creek and San Vicente Creeks after the removal of the dam on Mill Creek in 2021. However, we’ll see if there are any appreciable improvements in the San Lorenzo River watershed in the future. With all the large scale housing projects that are being built and planned, more demands for water use are inevitable. And we can surely expect drought years will occur and possibly increase. So, as the Anadromous Salmonid Habitat Conservation Plan is well intended, there are still significant headwinds facing our native fish. I do appreciate the efforts led by Chris Berry, watershed compliance manager for the Santa Cruz Water Department who has been working on this plan since 2001. Some of the local organizations like the Coastal Watershed Council and RCD of Santa Cruz County and the work they do also gives us reason for optimism. Let’s hope they succeed!
