DEPARTMENT OF AGRICULTURE
Forest Service
Lincoln National Forest, New Mexico, North Fork Eagle Creek Wells
Special Use Authorization
AGENCY: Forest Service, USDA.
ACTION: Notice of Intent to prepare an Environmental Impact Statement.
-----------------------------------------------------------------------
SUMMARY: The Lincoln National Forest will prepare an Environmental
Impact Statement (EIS) to document and publicly disclose environmental
effects of issuing a new special use permit to the Village of Ruidoso
(the applicant) for continued operation of their municipal water supply
wells on the North Fork of Eagle Creek, located on National Forest
System land. The new permit would include additional terms and
conditions for adaptive management (monitoring, evaluation, and
modification) to ensure management objectives are met. Management
objectives include:
(1) Providing water management flexibility and water conservation
incentives to the Village of Ruidoso, in a way that does not foreclose
opportunities to transfer a portion of their water rights for these
wells to locations off of National Forest System land; and
(2) Minimizing impacts of groundwater drawdown from this well field
to maintain surface flows and protect water-dependent ecosystems.
North Fork of Eagle Creek is located in the Sacramento Mountains of
south-central New Mexico in Lincoln County north of the Village of
Ruidoso and approximately 2.5 miles west of Alto, New Mexico.
DATES: Comments concerning the scope of the analysis must be received
by March 21, 2011. The draft EIS is expected in October 2011 and the
final EIS is expected in June 2012.

SUPPLEMENTARY INFORMATION:
Background
Urban and resort development and drought conditions have placed
increasing demands on surface water and groundwater resources of the
Eagle Creek Basin. During 2001-2006, the Village of Ruidoso, New Mexico
obtained approximately 31 percent of its water supply from the North
Fork well field. During drought conditions prior to 2006, over 50
percent of monthly total surface and groundwater diversions for the
Village came from the North Fork well field (Village of Ruidoso 2006).
The Village of Ruidoso drilled four production wells on National
Forest System land along North Fork Eagle Creek. Three of these wells
were put into service in 1988 and remain in use. Concerns have been
raised regarding effects of pumping water from these wells. A lawsuit
was filed in 2005 based on concerns that operating these wells could be
affecting streamflow in Eagle Creek. A 2006 settlement agreement
required the Lincoln National Forest to complete an environmental
analysis and undertake an independent study of effects of well pumping
before a new permit could be issued to the applicant.
The United States Geological Survey (USGS) conducted the
independent study from 2007-2009 to determine potential effects of the
North Fork well field on streamflow in the Eagle Creek Basin and to
provide data for this EIS. The final report was released on October 21,
2010. Findings show that during the study period there was less
available sustained baseflow than there was before the wells began
pumping in 1988.
When groundwater is pumped from the North Fork wells, it causes a
temporary decline in groundwater which lowers the water table and
creates an expanding cone of depression around the wells. If the cone
of depression continues to expand, it can impact water dependent
resources outside the stream corridor. This situation is exacerbated by
location of the wells within the stream channel, together with low
storage capacity of the aquifer.
Although years of below-average precipitation were recorded during
both time periods, there were no days of zero flow recorded at the
Eagle Creek gage from 1969-1980. No-flow days were recorded in 11 years
(totaling 789 days) of the 20 years analyzed after 1988, with 8 of the
last 10 years having no-flow days. No-flow days occurred during periods
of both below-average and above-average precipitation during the study
period, but no-flow days did not occur during periods of below average
precipitation before 1988. It is important to note that the Eagle Creek
gage measures flow from both North Fork and South Fork tributaries.
Purpose and Need for Action
There is a need for (1) authorizing, under a special use permit,
the Village of Ruidoso's legal right to access and divert groundwater
from its North Fork Eagle Creek wells on National Forest System land,
as an important part of the municipal water supply system that Ruidoso
residents and visitors rely upon; and (2) protecting natural resources
on the national forest by maintaining adequate surface and groundwater
flows to sustain or improve riparian and aquatic ecosystems that may be
affected by groundwater drawdown from the pumping of these wells.
Proposed Action
The Forest Service proposes to authorize, under a new special use
permit, the continued presence and operation of four municipal supply
water wells (3 equipped and 1 unequipped) and associated monitoring
wells, well-house control station and underground pipelines and
powerlines on National Forest System land in the North Fork of Eagle
Creek drainage. The new permit could be authorized for up
[[Page 6115]]
to 30 years, with stipulations for review and verification of the
permit terms and conditions at least every 5 to 10 years. The new
permit would be similar to the expired permit, with additional terms
and conditions reflecting current adaptive management strategies which
both respond to the purpose and need for action, and mitigate potential
adverse impacts to surface and groundwater water resources from well
operations.
The adaptive management strategy would take into consideration the
dynamic nature of groundwater systems by establishing a feedback
process to guide the management of groundwater withdrawal rates over
time. The NFEC basin is characterized as highly transmissive (water
moves through it easily), yet with a relatively low groundwater storage
capacity; two characteristics that make it sensitive to variations in
precipitation patterns and intensity.
Thresholds would be established for streamflows, water table
depths, and riparian vegetation, as described below. Exceeding these
thresholds would trigger implementation of adaptive management
option(s) to mitigate the impact to surface resources. Adaptive
management options currently under consideration include limitations on
groundwater withdrawal rates; cessation of pumping for short periods;
and/or surface flow augmentation. These options are simply an initial
list being considered at this stage of planning; they may be revised as
more analysis and evaluation is conducted during preparation of the
EIS. In addition, a threshold would be established for the total volume
of water withdrawn from the applicant's wells over a consecutive three-
year period, where exceeding the threshold would trigger a review of
the other thresholds and mitigations to prevent degradation of surface
resources.
The proposed action would require the applicant and Forest Service
to work in partnership, with assistance from the USGS, to conduct
monitoring and adaptive management of ground and surface water
resources. Four key monitoring indicators would be used, as described
below, to evaluate effectiveness of this management strategy. This
adaptive management strategy would be incorporated into terms and
conditions of the permit.
Monitoring Indicators
North Fork Surface Flow Volume. This metric would act as an
indicator of surface and subsurface flows necessary to maintain or
improve existing riparian vegetation conditions along the NFEC below
the existing well field. The applicant would be responsible for
continued collection of surface water flow data from the Eagle Creek
stream gage, located just below the confluence of North Fork and South
Fork tributaries. This gage records surface flow volume rates
(quantities) in cubic feet per second (cfs). These data are collected
and stored by the USGS, and available to the Forest Service and public
on the USGS water data Web site (http://frwebgate.access.gpo.gov/cgi-bin/leaving.cgi?from=leavingFR.html&log=linklog&to=http://waterdata.usgs.gov/nwis).
If there are more than 20 days per year of no surface flow (less
than 0.01 cfs) over a period of three consecutive water years at the
Eagle Creek gage, or more than 30 no-flow days within any single water
year (October 1-September 30), the applicant must reduce groundwater
withdrawal rates from these wells. If either of those thresholds is
exceeded, then groundwater withdrawals from the North Fork wells would
be limited to 50 percent of the volumetric rate of surface flow at the
North Fork gage (which is upstream from the wells) until surface flow
at the Eagle Creek gage resumes.
The following parameters and assumptions form the baseline on which
the North Fork surface flow would be modeled and managed:
Using a 3-year running average allows for natural
fluctuations in precipitation and snowmelt runoff, and periodic short-
term drought cycles, considering historic trends.
The 3-year threshold of 20 no-flow days is equal to about
half the average number of no-flow days experienced since pumping began
(1988-2009), and should result in an improved trend in surface flows
and moisture regimes in the North Fork tributary and its associated
riparian area.
The number of no-flow days would be evaluated based on
real-time daily recordings from the Eagle Creek stream gage. No-flow is
defined as a daily recording of less than 0.01 cfs.
It is recognized that Eagle Creek stream gage includes
flow contributions from the South Fork tributary. For consistency with
data gathered since 1969, the Eagle Creek stream gage will continue to
be used, assuming that there will continue to be no measurable changes
in human development or water use within the North or South Fork
drainages. The South Fork and North Fork stream gages would also
continue to be used in long-term monitoring, but have insufficient
historical data to initially be used as an effective trigger.
Water Table Depth. This metric would provide a continuous indicator
of the status of groundwater storage within the NFEC basin. The
applicant would continue to maintain monitoring well MW-1B and collect
data on changes in the water table levels. Water table depth data (feet
below surface) would be collected by USGS and stored in the USGS
database. These data would be available to the Forest Service and
public on the USGS water data Web site.
Once 5 years of monitoring data from this well have been collected,
including the 2 years of data collected prior to developing this EIS,
the Forest Service would evaluate this data, and use the 5-year average
water table depth to establish a threshold for average water table
depth.
The applicant would be required to maintain an average water table
depth that is equal to or above this threshold over 3 consecutive water
years. If groundwater pumping of North Fork wells results in a
declining trend in the average water table depth over any 3 year
period, the applicant would reduce diversions from the wells until the
average water table depth is reestablished and the Forest Service
determines that pumping may resume without creating further departures
over a 3 year period.
Riparian Vegetation. This metric would provide an indicator of the
effects of groundwater withdrawal on the condition and trend of surface
resources in and downstream from the NFEC basin. The Forest Service
would fund annual or biannual monitoring of riparian vegetation in the
project area to include the approximately 2-mile section between the
wells and the Eagle Creek stream gage. This would provide a baseline so
that any future changes in riparian vegetation in this area would be
apparent with future monitoring. Long-term monitoring may occur on
riparian areas above the well field as well as on a separate but
similar stream reach (to use as a reference point). Monitoring would be
conducted through a combination of permanent photo points and field
inventories of vegetation canopy cover and species composition. Trends
in riparian vegetation canopy cover, composition, or conditions would
be evaluated and documented at least every 5 years.
If there are measurable declines in riparian vegetation canopy
cover, composition and/or condition over 5 years or longer, and the
number of no-flow days at the Eagle Creek stream gage continue to
average over 20 days per year, the Forest Service may require
diversions from the wells to be reduced to below 50 percent of the
annual average well diversions (afy) over the past five years, to help
restore riparian vegetation.
[[Page 6116]]
Well Pumping Volume. The applicant would continue daily monitoring
and recording of groundwater withdrawals through the North Fork wells
(pumping volumes in acre feet). Combined with precipitation and
streamflow records over time, this metric would be used to develop an
additional reliable indicator for modeling anticipated effects of
groundwater withdrawals on surface resources within the NFEC basin.
An initial threshold of 900 cumulative acre feet over any 3
consecutive water years (300 acre feet per year) would trigger a review
by the Forest Service of the current thresholds and mitigations at
maintaining or improving surface resource conditions. This threshold is
based on current modeling of the average groundwater recharge rate,
after subtracting other known and assumed water losses from the NFEC
system. If analysis results indicate that current thresholds and
mitigations are not sufficient to maintain surface resource conditions,
management of groundwater withdrawals would be adjusted to provide
additional protections against further degradation of riparian and
other surface resources within the NFEC basin.
Adjustments in Management of Water Withdrawals. Every 5 years that
the permit is in effect, or when triggered by exceeding the water
withdrawal threshold described above, the Forest Service would evaluate
and document monitoring results to determine effectiveness of the
adaptive strategy and determine whether an adjustment to the parameters
of this adaptive management strategy are warranted.
Based on the 5-year evaluations, the Forest Service may
relax or further restrict specific parameters of this adaptive
management strategy, with modification to the permit.
Adjusting these parameters would be based on Forest
Service determinations of the extent to which the North Fork well
operations are consistent with the purpose and need and identified
management objectives.
Adaptive management adjustments currently under consideration
include: Limitations on groundwater withdrawal rates; cessation of
pumping for short periods; and/or surface flow augmentation. These
groundwater management options are a preliminary list being considered
at this stage of planning; they may be revised as more analysis and
evaluation is conducted during preparation of the EIS.
Possible Alternatives
No Pumping Alternative: The Forest Service would not issue a new
permit for the applicant's North Fork well operations and maintenance;
the use of these wells would no longer be authorized and would be
discontinued.
No Action (No Change) Alternative: The Forest Service would issue a
new permit for the applicant's North Fork well operations and
maintenance with no change in existing well pumping operations; there
would be no specific stipulations or limitations on well operations and
the permit would be issued under the same terms, conditions, and
history of water use that has been in operation since 1988.
Stream Augmentation Alternative: This alternative, suggested by the
applicant, would be essentially the same as the proposed action
previously described, with one main difference. Exceeding the
thresholds previously described for streamflows, water table depths,
and riparian vegetation would trigger augmentation of streamflow by
pumping groundwater into the North Fork of Eagle Creek stream channel
to mitigate adverse impacts to surface resources.
Responsible Official
The Forest Supervisor of the Lincoln National Forest is the
deciding officer for this project. The Forest Supervisor will issue a
Record of Decision at the conclusion of the National Environmental
Policy Act (NEPA) process, and after evaluating public comments
received on the Draft EIS.
Decision Framework
The Forest Service is the lead agency for the project. Based on the
results of the NEPA analysis and consideration of public comments, the
Forest Supervisor will authorize implementation of one of the
following: (1) The agency's proposed action, including the adaptive
management strategy and any mitigation necessary to minimize or avoid
adverse impacts; or (2) an alternative way to meet the purpose and need
for action, including any applicable adaptive management strategy or
other mitigation necessary to minimize or avoid adverse impacts; or (3)
the No Action/No Change alternative or the No Pumping alternative.
Preliminary Issues
The main issue to be addressed is the effect that the proposed
continuation of well pumping may have on hydrologic resources (surface
water and groundwater) in the North Fork Basin, including potential
cumulative effects downstream in the larger Eagle Creek watershed.
Other issues identified thus far include effects of well pumping on
aquatic habitat and fish (particularly brook trout), downstream
recreational use (public use of streams for streamside recreation,
fishing, and wildlife viewing), riparian vegetation condition, and
municipal water supply.
Scoping Process
This notice of intent initiates the scoping process, which guides
development of this EIS. To assist the Forest Service in identifying
and considering concerns about the possible consequences (effects) of
the proposed action or possible alternatives being considered, comments
should be as specific as possible. A public open house will be held at
the Ruidoso Middle School (123 Warrior Drive, Ruidoso, New Mexico
88345) on Thursday, February 17 from 5 p.m. to 7:30 p.m. Forest Service
staff will be on hand to meet with the public, answer questions, and
discuss the project and process. Comments may be submitted at the
meeting, by e-mail, fax or letter within the 45-day scoping period.
It is important that reviewers provide comments at such times and
in such a way that they are useful to the Agency's preparation of the
EIS. Therefore, comments should be provided prior to the close of the
scoping period and should clearly articulate the reviewer's concerns
and contentions. Comments, however, are welcome throughout the planning
process.
Comments received in response to this solicitation, including names
and addresses of commenters, will be part of the public record for this
proposed action. Comments submitted anonymously will be accepted and
considered; however, anonymous commenters will have no standing to
participate in subsequent administrative review or judicial review.
