I have fished chalk springs many many times, and think i know it pretty well, Yes its very very clear but think of this as a bonus as it lets you see the fish.!
If i were to offer any advice it would be as follows:
Keep Mobile! - Some fishers root themselves to the spot near a shoal of fish and haul out a couple of 2 pounders. great, but not what CS is about. Have a look everywhere and you'll see some very large browns well into double figures to have a cast at!
Don't ignore big flies. I've been extremely lucky there and have had 38 double figure browns from CS (like the one in my avatar) Theyre wonderful, good conditioned, and very hard fighting fish. Most of my big browns have come on weighted marabou tailed 'damsels' in black or green. Either let the fish cometo the fly and retrieve it off the bottom, or bring the fly from behind the fish and into his line of sight for a follow. DO NOT stop the retrieve, as the fish will always reject it. The best way to get a take here is to have the brown follow the fly, then as he closes in, give the fly a tug to pull it away! the fish will then usually take very aggressively
Don't give up! - As long as you don't spook them, the big browns will often react to your 5th, 10th change of fly you'll get no interest, no interest, no interest - WHAM! however if he appears scared of your fly - move on, there'll be another in there!
Hotspots..? Try the top and bottom ends of the East Lake, and under the trees on the right hand side. At the far end is an overhanging willow, and if the sun's up, there will always be a big brown under here. In the S Lake, try under the trees on the far bank, although casting is difficult, and all along the bottom bank near the willow. this is where the water's deepest and holds the big fish. the top end of the S lake also has a deep hole that's worth exploring.
The W Lake takes a bit of a thrashing, and while there are always fish in here, don't waste too much time. they;ll probably have seen a snagger or two trying to deliberately foul hook them



Have a look at the Top inflow in the N pool too, as this often holds a surprise...
