6/15/2012 Mer 40-70 THIS IS A REPORT FOR CLEAR CUT TO CREAM SINK SECTION OF LEON (post week of ~12" of rain in area): Clear Cut sink low vis (3-5') down to 32' in basin. Sulfur/smokey layers in basin. Clear at start of mainline. 40-50' vis just downstream of Clear Cut, milky, tinge of green or possibly slightly tannic. Noticeable flow, up since May, which increased downstream of Wood Sink. Further downstream we went, vis improved to 70'ish and milkiness decreased. All sinks downstream of Clear Cut to/including Cream appeared clear to the surface.
5/6/2012 Mer 60-80' THIS IS A REPORT FOR CLEARCUT TO PROMISE SECTION OF LEON: Clear Cut Sink is low vis (5'ish if you don't kick up the bottom) down to 25'ish feet. Clears up just above the platform. 60-80' in cave with noticeable flow, some milkiness. Bring a rope to tie to tree to help with Clearcut Sink exit.
5/6/2012 Mer 80' Sink clear to surface. (Entered at Clear Cut and swam to and surfaced in Promise before returning to Clear Cut). Noticeable flow even at surface of sink.
1/19/2011 Mathew Bull Tanic Sinks have blown out from the recent rains.
12/4/2010 Mathew Bull 40' Waters blue/green with a bit of smoke in it.
11/28/2010 Mathew Bull 40-50' Little milky, likely from runnoff after rains the day before yesterday. Should flush out and be closer to 60' shortly.
11/13/2010 Mathew Bull 60' Vis is great, well over what my primary could handle with a little milk in it. Had a great dive!
11/6/2010 Mathew Bull 40-60' Same as on the 4th
11/4/2010 Mathew Bull 40-60' A little milk and very little particulate, but still blue despite the recent rains. Vis was enough to enough to enjoy the dive and see alot of the walls. Everything is great in the area. I actually entered at Cream Sink and headed upstream just short of ClearCut.
5/31/2010 Mathew Bull 40-60' Kinda green, but clear, little bit of flow but very nice time to dive the area. Its been tannic for several months, nice to be able to jump back in here...
4/9/2010 Mathew Bull 5' and Tannic Didn't dive, heavily tannic from the surface.
12/5/2009 Mathew Bull Blown Conditions blown from recent rains, trails to the area were cleared by the WCDC though.
11/14/2009 Mathew Bull 30-40' and slightly green Actually dove from Cream Sink, just upstream from Promise and Go Between Sinks. Conditions were great
10/10/2009 Mathew Bull Clear from the surface Looked clear and blue from the surface, made me wish I left home earlier to have time to dive.
6/6/2009 Mathew Bull 5' and tannic Didn't dive, lots of particulate, water was very tannic.
5/24/2009 Mathew Bull 40-50' Still a greenish tint, but visibility wasn't bad as long as you didn't kick up the bottom. Went as far as Trench, upstream, with consistant conditions.
2/7/2009 Mathew Bull 30-40' Waters low, visibility is great albeit a bit greenish still.
10/5/2008 Mathew Bull 30' Visibility is returning to the area after Fay and several other tropical hiccups and alot of rainfall. Water is still greenish, but clear and the dive is great.
6/22/2008 Mathew Bull 50'ish Visibility down a little, likely due to the thunderstorm we dove through throwing runoff and particulate into the water. Still a great dive and we had clear skies by the time we exitted.
6/8/2008 Mathew Bull 60 ' Flows still down, water probably a bit cleaner than 3 weeks ago, and still even more swimmers showing up to beat the heat.
5/19/2008 Mathew Bull 60' Flows down, water levels are down, the water is clear with an ever so slight green tinge. Lots of swimmers on the surface who have no problem with going through anything you've left on the surface during the dive. Watch out for underaged, puking, drunk chicks.
3/2/2008 Mathew Bull 5' from the surface, tannic and smokey Didn't dive, but the sinks throughout this length of system are tannic and very smokey from the surface. Flow seems to be kickin too.
2/3/2008 Mathew Bull 15-20' Slight green-yellow hue from a bit of tannic intrusion, water was still 68F, so there wasn't enough intrusion to drop temps. Headed upstream from Promise to Go Between, Fern, Cream, Woods, and Trench with 15-20' visibility and positive flow.
