Slit Drainage Holes 12 & 13 Hawk (Starting August 4th / 2014)

The slit drainage project that will enhance drainage on Hawk holes 12 & 13 is scheduled to begin immediately following club championship on August 4th. The drainage installation on these two holes is scheduled to be completed by the end of August. The goal is to minimize member disruption so the contractors have been asked to keep the work area limited to one hole at a time. However, there will likely be some over-lap and workers will be seen on both holes periodically. While the contractor is working on a hole, the golf hole may play as a par 3, hitting to the green only from a temporary tee. There may be a temporary green or the hole may be closed. We will try to keep the closures to a minimum.

Member’s golf car traffic will also be affected during this process. When the contractors are driving down the cart paths with equipment full of sand and gravels, members will be given direction to drive on the grass to minimize the equipment from causing damage.

We would like to thank the membership in advance for your understanding and patience. We believe the short term pain is worth the long term gain as we have seen on the previous holes on 6&7 Hawk.

The project is scheduled to be completed in 3 weeks. Weather will have a factor in the speed in which the contractor can complete the project. If the weather is dry, we expect the project to be completed in 3 weeks. The equipment cannot work in wet conditions therefore if wet conditions persist, the project will take longer.

Hawk Greens Aeration

The annual Hawk Golf Course greens aeration program is scheduled for Monday, July 7th. The golf course will be closed for the day to provide Turf Care staff the time required to complete this essential procedure.

Greens Aeration Information:

Soil Testing:

  • Greens are soil tested 1 month prior to the scheduled aeration to determine requirements for aeration. The soil test provides scientific information that helps to determine what type of aeration is best for our greens. The categories of the soil test include information such as:
    • Compaction - How hard the green surface has become over the past calendar year
    • Air porosity ratio - Grass needs a correct balance of air & water for drainage and root growth
    • Water infiltration - How quick water is able to penetrate the green surface
    • Water holding capacity - Too much leads to weak turf
    • Organic matter percentage - "Sponginess" that leads to excessive ball marking & slow green speeds
Greens Aeration Process:
  • Greens will be aerated with an 11mm diameter hollow tine
  • Tines penetrate the surface of the green approximately 4"
  • Approximately 3% of the green surface is affected by the holes
  • Aeration cores are removed by staff using snow shovels
  • Each green is topdressed with approximately 2 tonnes of sand to fill the aeration holes
  • One of the most critical aspects of the process is to ensure all aeration holes are filled to the top with sand
    • This is a very labour intensive process using brooms, drag mats and blowers
    • When this process is completed to the highest standard, the greens will putt smooth even with aeration holes
    • Dry conditions are essential for success
  • Greens are fertilized 2 times the week prior to aeration and once immediately following aeration. These fertilizer applications maximize specific turf growth that will minimize the recovery process and the length of time the greens have holes in them
  • Weather that provides good growing conditions has a significant impact on the turf recovery process, this is why greens are aerated mid-season
Fun Fact:
Putting green aeration is an essential but somewhat disruptive process that golfers are not normally fond of. The only people that dislike the greens aeration process more that golfers are Golf Superintendents and staff. Greens aeration is always a stressful, expensive (overtime), labour intensive process that usually ends up providing less that positive feedback from golfers.

With a well planned and executed process and a little luck from Mother Nature, the greens will be back in great shape within days.
