Played Chino Creek, late morning on a Tuesday. I like the Creek course, where as the Butterfield course, I would rather not play, unless my arm is twisted a bit.
From T to green I would rate this course above 6, but anything right or left of the fairway and sometimes of the greens, are horrible. Greenside traps are okay to play out of, but pebbles left on the green and in your putting path, make them poor.
They have recently purchased new, used carts, parking brakes did not work well, but overall a huge upgrade, from the carts they had, which looked like they were from the 70's.
Sounds like warfare going on from the nearby shooting range.
Would love to see them update, modernize the layout at Butterfield.

Played 11/6 on a Thur. morning. The more I play this course the more I enjoy and the more creeps closer to my favorites. The course from T to green was in very good shape, including the greens which were punched just over two weeks ago, they were fast and just a hint of some bumpiness on some holes, should be perfect in a week.
Excellent practice facility. Range was in good shape with plenty of grass to hit from. Nice chipping area. Definitely the place to practice if you are a local.
The real prize is the layout, very straight forward, but still makes you think what club to hit from the T, 127 slope from the whites, which is just right for my game.
A golfers golf course! Can't wait to go back.

2nd time playing here, since 2.5 years ago. Took advantage of the coupon, TY GK and Redhawk, very good deal. Facilities are very nice and customer service was friendly. Course conditions were in good shape. Layout is fun, be careful with 1st and last holes, more tricky than difficult. Only knock on the course is the way shorter than normal par 3's. Par 3 over water, looks like it belongs at Augusta, unfortunately it was the bumpiest of all the greens. I will probably be back soon to play again.

Played late morning on a Thursday, 10/16. Greens were bumpy and still healing from aeration, but very playable, give another two weeks and greens should be in very good shape, I did not notice any disease problem, so that may be under control now. Great layout and friendly staff. Pace was very good, never waited and never pressed.

Played Wednesday afternoon. Course just reopened after maintenance, all was in very good shape, except greens, which were a tad bumpy and just medium speed, and T's which had long rye and not as flat as I like(minor). Greens should be perfect in a week or two, would play again tomorrow, if I could.

Played Thursday, 7/10 mid-morning T time. The North was having a amateur champion tourney, so of course that means the South was going to be busy. And it was, the bright side was, their was a lot young guys and girls on the range who could really play.
All conditions were 7+, but the greens are very nice, smooth and lush, rolling at medium-fast speed, a fast is the only thing from me rating them a 10.
Waited on every shot, dragged on a bit at 4.45 minute round.

Tips
Bring your driver, almost every par 4 or 5 is a driving hole, long and wide, even from the whites.
They are working on the traps, even adding a few new ones. The white ones are done and have good sand in them and are very pretty. The brown ones are not done and hard packed, but playable.

Played a Thursday, mid morning T-time. Course is in 7+ condition all the way around with the exception of the greens, 9+ condition almost immaculate, rolling much faster than any other course that I have played in the IE, the last couple of months.
They are draining the lakes around the clubhouse is the only complaint, minor, just effects the beauty of the course, not the play.

Played a Sunday twilight round not much changed since my last review, but a single joined our threesome, it was not until late in the round that I noticed a Greenskeeper tag on his bag, first time I've come across someone from the community. Edgar was a lot a fun to play with, I was impressed with not only the length of his drives, but with his accuracy. Feel free to join us any time you want.

Really enjoy the new carts. Plenty of un-raked bunkers and unrepaired ball marks on the greens, for how good of shape the greens are in, you would think the golfers would do their part in keeping them in shape. Too bad.

Played early afternoon on a Monday. 95% of my golf is played right here in the IE, so how is it that I waited so long to play this great course. I am really fond of my top 5 IE courses, this course is easily going to bump one of those courses to 6th position.

Whenever I play a course a for the first time, I like to check the tips, posted below by other players. I forgot to on this occasion, $20 for a yardage book. No thanks. The course was pretty much the way you see it from the T. No hidden lakes, or blind spots, but there was a couple of holes where there appeared to be landing areas, than a valley, was not sure if there was heavy rough down there or what? It caused me to probably hit poor drives, from what I remember it was normal fairway.

Everything was in great condition, 7+ condition, but the greens were just an excellent design and very challenging, if you had a long putt you likely had a double breaker. I kept hearing how challenging this course was, from the whites it's a whopping 132 rating and 6300 yards, blues top off at 7000. For a 16 HCP, I thought it was the right mix of challenge and fun, and would have scored very well except for a couple of blow up holes.

I absolutely loved this course, but here is a few suggestions and critiques:

No cart girl, I am okay with this, there our coolers on the cart. Tip- there is a large ice bucket located at the entrance of the under ground cart area at the turn.

Carts are in great shape, but no GPS, markers our not readily visible. Having boulders marking 200 and in, makes things easier and faster.

I usually like a course to have at least 5 holes with water on them, just 3 here from what I remember, but the design was so good I did not miss them that much.

Tip- Do a stay and play in this area, play Oak Valley then Soboba in San Jacinto, you will not be disappointed and it's a bit cooler than Palm Springs. Morongo has great rooms.

Played a twilight round on Tuesday 6/24, this is my home course, I play several times a month here and I am always happy with the conditions and the service, pop can be a challenge at times.

Aside from pop my biggest complaint was the carts, they would let off this annoying beeping sound that was becoming more and more common. That's all changed now, they have BRAND NEW CARTS!! Thank you so much.

Greens-9
T's-8
Fairways-7; some brown spots from the heat, but never a bad lie.
Rough- 5; same as the fairways x2
Sand-8; always have sand in them, sometimes too much.
Layout-7; fun canyon golf.

Played 5/29, here at one of my favorites in the IE. After I told my group I made reservation here, one told me they had just punched the greens a couple of weeks ago. Whoops! Forgot to check.
No problem though, the greens were healing nicely a head of schedule, I would have guessed they were punched about 4 weeks ago. No sand at all, just a bit bumpier and slower than usual, normally quick here, now med-fast and straight.
The rest of the course was in great shape, with only some brown spots in the fairway and rough, from the heat.
Had the course to ourselves! Couldn't believe it. Wonderful time, always worth the drive and fee.

Played Monday 5/5, late afternoon T time.
Greens are still recovering from punching and may be more than a couple of weeks away from healing completely.
Some T's were in bad shape appearance wise, but they were on top of it, as at least two T's had recently been re-sodded. Despite this, I never had a problem finding decent footing to T my ball up.
Fairways were in very good shape, never had a bad lie.
Sand had good quality sand, but was moist at best and muddy in some places, surprising on a warm breezy afternoon.
Layout is fun, pace was 4 hours, I would play it again at the price I paid, but hold off for weeks before paying rack.
