What is NRWMAC?

NRWMACs primary goals for lake Nacimiento water management

Maximize water levels up to the ideal level 790 ft., which stores more water for recreation & agriculture.

Maintenance of constant lake levels from May 1 through September 30 to enhance recreation activities and fish habitat.

Maintain year-to-year elevations through prudent management of transfers and releases.

If the tunnel is built, utilize transferred water from Nacimiento, being stored in San Antonio, prior to releasing water from Nacimiento.

What does NRWMAC do for you?

NRWMAC stands up for you at all of the Lake-related meetings held in Monterey and San Luis Obispo Counties. There is constant pressure from Monterey County for more water. The meetings we attend occur monthly in Salinas but in between are many other technical and operational meetings and seminars that require our presence

NRWMAC saw early on that the Quagga Mussel could be the end of our beautiful lake. We visited contaminated lakes as far away as Lake Mead to see the damage done. We, in conjunction with SLO County, and Monterey County, created a plan and we train all inspectors for all boats entering our lake. Our plan is updated yearly and the training is on -going. This alone is nearly a full time (unpaid) job.

NRWMAC has brought back the idea of a pipeline between Nacimiento and San Antonio, as another way to manage the amount of water stored. This idea has been taken up by Monterey County, who has designed their own version, …much different from NRWMAC’s vision. Their version may not benefit Lake Nacimiento owners and enthusiasts. This promises to be an expensive process and a lengthy series of meetings and we will need your help.

NRWMAC supports the rights of all of the property owners and recreational enthusiasts. At Lake Nacimiento.

DON’T LET OUR LAKE GET INFESTED!!

Make sure your vessel is Clean, Drained, and Dry.
Make sure you have a current Vessel Screening Permit, or a Resident Vessel Sticker and Resident Vessel Certificate.
If you are on the lake without a Vessel Screening Permit or a Resident Vessel Sticker and Certificate you are subject to a $2000 fine.
Repeated violation of the above may result in your launch ramp being closed.

Maximizing water levels for Property Owners, Visitors, and Water Enthusiasts

What is an Interlake Tunnel and What Does it Mean for You?

Monterey County Water Resources Agency (MCWRA) is proposing building a tunnel to divert water from Lake Nacimiento into Lake San Antonio. The Nacimiento Regional Water Management Advisory Committee (NRWMAC) is concerned how the tunnel might affect Lake Nacimiento lake levels, recreation activities, property values, and water availability.
