Historically, the Town's interest in the number one priority Francisco & Daigre Mill water right
provides the only reliable direct flow yield during drought conditions, and is significantly less than
the Town's demand. During these times, or seasonal periods of low flow in the River, the Town
relies on water stored in the lakes to supplement its demand for raw water.
Project Description
The objective of this Project is to rehabilitate the North Lake dam; thereby removing the restriction
imposed by the SEO. The following alternatives were considered.
Alternative No. 1— No Action: Raw water storage is essential for meeting the Town's municipal
water supply demand. North Lake dam is currently under restriction and South Lake dam is
showing signs of distress, and faces the possibility of a restriction in the near future; therefore, the
alternative has been dismissed.
Alternative No. 2 — North Lake Dam Rehabilitation: The alternative involves breaching of the dam
to allow for reconstruction of the outlet works and installation of a toe drain filter system, restoring
the 17 AF of storage lost under the restriction. This alternative was selected for its ability to restore
the Town's raw water storage capacity in the most economical and environmentally sensitive
fashion.
This alternative requires SEO approval of construction documents, specifications, hydrology report
and a geotechnical stability analysis. The only permit anticipated is a storm water discharge permit.
It will be the responsibility of the contractor to secure the permit prior to beginning construction.
Existing site access is adequate to accommodate the proposed construction activities; therefore, no
easement acquisitions are planned.
The initial submittal of engineering documents to the SEO is scheduled for January 2012. Approval
is expected by July 2012, with contracting and bidding to follow. Construction is scheduled to
commence in the fall of 2012 or spring of 2013, and should take three months to complete. The
total project cost is estimated at $410,000, and is summarized in the following table.
