Re:2025 Dam Safety Surveillance and Monitoring Report (DSSMR)
Dear Mr. Moseley:
This is in response to a letter dated March 26, 2026,from Ms. Kristen McKillop
that submitted the DSSMR for multiple Dams, which is part of the South Feather Power
Project, FERC No. 2088. We have reviewed the submittal, and we have the following
comments:
P-2088 et al
1.Apart from the body of the reports, the appendix of each DSSMR was not
properly labeled as CEII. All future DSSMRs should contain the
appropriate labels. This comment does not require a response.
Sly Creek Dam and Miners Ranch Dam
2.Regarding threshold and action level exceedances,we recognize that these
exceedances may not represent a dam safety issue and are often affected by
factors like precipitation for these projects. However, they were set as
monitoring levels for a reason. As noted by the Miners Ranch DSSMR
Section 4.3 these exceedances are “likely not related to seepage”, based on
data review at some point after the exceedance occurred leaving an
implication that there is some chance it is related to seepage. Typically, an
exceedance warrants some form of immediate response to confirm the
safety of the structure (e.g.data review, increased monitoring frequency,
site visits to confirm remote monitoring data, contacting chief dam safety
engineer,notifying us etc…). Future DSSMR narratives should clearly
describe the actions taken in response to exceedances to confirm whether a
Document Accession #: 20260522-3037 Filed Date: 05/22/2026
2
dam safety issue was developing. This includes precipitation data and
information if you determine the cause to be a result of a precipitation
event.
Ponderosa Diversion Dam
3.The 2024 DSSMR indicated that Comment 3 from our January 17, 2025
letter, regarding the recording of visual observations for seepage near the
toe of Ponderosa Dam (when not submerged by Lake Oroville) would be
implemented. We do not see any observations of whether there was any
seepage noted at this location,or if Lake Oroville was ever low enough in
the year to observe any seepage at this location. This information should be
added to future DSSMRs. These seepage checks at the downstream toe of
the dam should be added to your routine inspection forms.
Within 30 days of the date of this letter,address our comments or provide a plan
and schedule to address our comments. File your submittal using our eFiling system at
