Fixing the Mill Pond
2002 the lake association funded an effort to fix the continually
leaking Mill Pond. Spirit Lake is unusual in having a sealed clay
bottom over highly drainable gravel, which results in rapid draining if
the seal is broken. Several series of years, where dry conditions
led to the Mill Pond drying out and cracking, made it become like a
sieve... A layer of woven plastic material was laid in strips
after digging down several feet in the dried mud. In the photo
above a cofferdam blocks the water from entering the Mill Pond while
the construction effort continued...
The project took months of repetitive labor...
fall rains didn't help matters...
In spite of several extremely dry summers since it was applied, only
minor repairs have been needed to keep the lake level more satisfactory
since the completion of the project.
Native pond plants were diminished by the project, but have begun a healthy recovery...
