Additional Remarks or Updates |
Rec'd call from local resident about fracture in bedrock at vertical face at principal spillway (see photos). Appears that boulder could break off face. No immediate concerns to dam noted. Recommended Sauk Cnty continue to monitor and will need to reinspect if/when boulder breaks off. See follow-up inspection report. NRCS did conductivity resistance testing in channel from lake to spillway (still awaiting results). |
