3 Irrigation System A) GENERAL Installed in 2006/07 Rainbird system supplied and installed by MacDonald's Irrigation for $232, spray nozzles running at 80 psi 20 nozzles+ added since then Main pumps and controls supplied by Pumptronics for $85,300 in fall 2004 Twin Gould pumps each 800 psi 34.4 hp, 1770 rpm, Eff 85.2% Pumphouse and electrical built in fall 2004 were budgeted at $27,500 System designed to apply 1" of irrigation per week (industry rule of thumb) System not run at capacity until 2016 because of lack of need and pump failure at high capacity. Pump failure eventually solved in 2016 by Irriplus (Barry Stone) System twice tested since then at 256,000 usgpm - full capacity Had little impact on 2016 irrigation issue - even with 35% reduced pumping capacity we could have irrigated far more than we did if we believed water was available Much work done in-house in 2016 to repair defective decoders/nozzles. System is now working well. A complete audit was conducted in early 2017 to ensure the spray heads are level and operating.

6 Current Water Storage A) GENERAL Our pond was expanded in the fall of 2004 at a budgeted cost of $175,000. Turf repairs were over and above this. Capacity is 6,367,000 igal Confirmed by Mac Williams Engineering September 29/16 along with as-builts 99% of the water appears to be recoverable Slope is 2:1 (Run:Fall) Min depth designed as 10', max depth at pump in take is 13' Surface area when full - 117,000 sq ft Surface area when down 10 ft - 64,000 sq ft Pond can be drained to the ocean. Depth checks and visual inspection after the pond was drained in Nov/17 show that capacity is essentially at the original design.

15 Soil Moisture A) GENERAL Per the NS Soil Survey of Lunenburg County, Chester Golf Club has the following soils; Bridgewater Sandy Loam On the high ground and ocean side & Bridgewater Loam Drumlin #1,2,3,4,5,6,7,8,9,10,11,12,16,17,18 Riverport Sandy Loam On the low ground inland #13,14,15 Both Bridgewater groups are not particularly fertile because they are stoney and have rapid drainage which leaches the nutrients. The good news is they drain quite well The Bridgewater Sandy Loam is does not retain water well and is considered a "droughty" soil. The Riverport group is a moderate to poor draining soil. Rocky and low fertility. B) SOIL TEXTURE CLASSIFICATION (Completed in 2017) Completed by removing particles larger than 2mm, mixing soil in water and measuring the depth of settled layers. This is approximate as there are only small distinctions between fine sand and silt, or fine silt and clay.

20 Turf Water Requirements A) GENERAL The conventional "rule of thumb" is that healthy turf in our northern climate requires 1" water per week. Irrigation systems are designed to supply this without exceeding the soil's ability to absorb it. No "rule of thumb" is likely to describe what turf requires when subjected to: High winds Extreme temperatures Low cutting height Shaded, protected areas vs areas open to sun and wind Variation in application of water due to system design The Superintendent will adjust irrigation to suit whatever the turf currently needs This may include hand watering when greens are under severe stress.
