Pros:
Variety: West Lake has a little bit of everything. There are some predominantly open hills and other holes with tighter fairways. There is also a solid variety in hole length. This is a huge plus in my book.
Memorable holes: As many reviewers have already noted, there are a number of holes at West Lake that are fantastic holes. My personal favorite was Hole #5. With windy conditions, this is a pretty daunting tee shot. I also liked #2 and #23.
Fairway maintenance: I designate "fairway" here (see cons below) because the fairways were well manicured. The landscaping around the course (sparse trees) was very nice as well.
Overall design: I mentioned the variety earlier, but the design of the holes was really good on 80-90% of the holes. There were a few multi-shot holes, at least for a 300-320' thrower like myself. Definitely not a drive-putt course.
Score differential: I like courses that provide ample opportunities for scoring variance. There are some courses that you play and you know if you play it again 100 times you will likely be within 4 or 5 strokes 99% of the time. West Lake is the exact opposite. I could see myself shooting under par...and I could see myself shooting way over par if I was struggling off the tee.
Cons:
Navigation and Signage: Usually if signs are present, it is a plus in my book. However, the signs need to be accurate and give the player a general idea of the hole. At least twice we threw our drives only to find that the pin was in a different area than we thought. On hole #7, the layout and sign indicate an anhyzer across the valley. After throwing what I thought was a great shot that would leave me a putt, we all realized that the hole was actually a hyzer, and the member of our foursome who threw the worst shot (intended anhyzer but flexed out hard) ended up with the better scoring chance. We could have re-teed, but it turned out to be no big deal as we all carded 3s. This happened again on hole #9, but we caught it immediately after our drives. The sign indicates a straight shot, but the hole is actuallya fairly strong hyzer. Hole #20 was impossible to find, so we ended up walking down its fairway from the parking lot. Who knew that you should backtrack down a blind fairway (#19) in order to get to the next hole. Definite design flaw here.
Off-fairway maintenance: I agree that errant shots should be punished. However, I also believe they should be able to be located unless they were attrocious. I believe it was Hole #12 where there is a narrowly mowed fairway with a treeline down the right side, thick rough down the left, and a wall of trees about 280 feet away with a 10' wide gap to hit that opens up to the pin close to the water. The pin location was great, but the tall grass bordering on the lefft of the fairway needed to be mowed. Most players are going to hit that gap less than 20% of the time. The hole could be played by rec players as a hyzer into where the high grass is now, followed by another hyzer to get through the gap. This grass was high to the point that finding discs was difficult, and the wall of trees was dense and thick and probably collects 90% of the shots where the player goes for it. I actually hit the gap, but I probably wouldn't hit it regularly. We spent at least 15 minutes looking for a couple of discs on this hole alone. The next hole (levee hole) really only allows you to use half of the levee. If someone would weed-eat the left side of the levee, an errant shot over there would still be punished with a severe uphill 2nd shot and possible water trouble on the left. However, the player is essentially forced to manuever along the right side of the levee only. This could be fresutrating for some players.
Proximity to other park activities: as with any multi-use park course, there are going to be some issues with other users. On this course there are picnic tables, parking lots, playgrounds, and ballfields that could possibly come into play. On a crowded day, play with discretion.
Other Thoughts:
West Lake Park has a lot of things going for it. The design is worthy of a "phenomenal" designation. However, there are a few cons that detract from its score, in my opinion. I settled on a 4.0 for excellent. It gets docked .25 each in my book for navigation issues, ease of play. By ease of play, I don't mean lack of challenge. I mean that you have to search for discs in many places that are slightly errant and you have to monitor the whereabouts of other park users. These factors alone caused us to take about 45 minutes longer to finish the round than we should have. There are also a couple of long walks, to and from the "levee loop".
While I have read a lot of reviews that said this was an uber-challenging course, I simply did not find this to be the case. (except for #20...which was just a ridiculous hole) It was a good challenge, but I wouldn't put it in the top 20 hardest courses I've played...and I have only played about 110 or so. This is a course that I definitely feel like I could get close to par with only a few rounds. I think it gives the perception of difficulty because it is 24 holes, mostly in the open, and on a hot day the elements can really wear you down. This makes it a grind, but not necessarily difficult.
In conclusion, West Lake is an "excellent" course. I can't in good faith give it a score higher than that. It was definitely worth the stop on our trip. After playing some of the supposed best courses in Iowa, Minnesota, and Wisconsin on this trip, I must admit that I feel that some of the better courses in this region have inflated scores. West Lake is definitely an "excellent" course, but it has too many issues to be considered "phenomenal", and is not even close to "the best of the best". However, if you are in the area, it is definitely worth playing. I wouldn't plan a specific trip to play this course alone, but I hear the Quad Cities has a fair amount of courses so there could be plenty to keep you busy on a weekend trip. If you go that route, definitely include West Lake Park.
