Dam Removal

If you've watched the national news lately, you've likely seen the concerns about dams failing due to the heavy rains in the west.  In contrast to this, we've developed some dams on the golf course which we weren't looking for, and would like to get rid of.

These are referred to as "collar dams" and develop primarily due to sand accumulation from both bunker and topdressing sand over a period of time.  On several greens, the collar is now higher than the putting surface, thus preventing surface run-off of rain water.

Removing the dam requires a bit of delicate surgery on the green, collar and surrounds.  The first step includes checking the existing grades with a transit, and determining the area which needs to be regraded.  In order to have a smooth tie-in to the surrounding area, it's often necessary to start the grading well beyond the low point.

In the case of #3, we knew that an issue existed prior to last fall's construction on the surrounds.  The grading adjacent to the green and bunkers was done in a manner which would allow us to get some drainage once the green itself was addressed this winter.

The finished product.  The sod seams have been topdressed.  Winter (if that's really the season we're in) is typically the best time for us to tackle a job like this, as the sod will not require babysitting.  Now that it has a little more slope to it, this will truly be a knee-knocker of a pin placement...
