September 27

     We finally have cooler weather that is much more fitting for the time of year.  It's also overcast and rainy today, which will make fishing BWOs, nymphs and streamers very effective.  These conditions are supposed to remain consistent over at least the next several days, so if you've been looking to get some good dry fly fishing in, Rock Creek (as well as the neighboring rivers) should definitely be picking up.  More in a couple of days.

September 23

     We have had some surprisingly hot weather for this time of the year, and we've been reaching temperatures in the 80s the past several days.  The forecast says that this will keep happening until this weekend, and then we'll drop back into normal fall temperatures.  But for the time being, dry fly fishing is especially hard in the late afternoon and early evening.  If you decide to head out, try small mayflies or attractors first thing in the morning when the sun hits the water, and then switch over to hopper, ant, or big attractor patterns as you get into late morning and afternoon.  Put those crippled emergers and small beadhead nymphs behind your dries to improve your odds, as some of these fish aren't coming all the way to the surface.

     For the time being, nymphing is definitely the better option.  Prince nymphs will work throughout the day, as will girdle bugs and Copper Johns.  Streamers are also doing very well here, so fish them in the deeper holes.  As we approach the end of September, we are seeing fewer and fewer fishermen out there, which means the pressure on the fish is decreasing every day.  So if you're looking to escape the crowds (especially in the middle of the week), Rock Creek is the place to be.

     It's been a good week of fishing since my last report, and though the mornings are getting really cold, the rest of the day has still been reaching the 70s and even 80s, so dry fly fishing with big bugs like hoppers and ants is still a viable option.

     If you decide to head out first thing in the morning, your best bet is to stick with nymph patterns like Princes and orange serendipities.  I recommend doing a big nymph with a smaller one trailing 1.5 feet behind it to improve your odds.  Streamers in the morning can be very good as well, especially black wooly buggers or leech patterns.

     In the late morning and early afternoon, it's time to switch over to some dry flies.  Grasshopper patterns have been effective lately, as are black ants.  Behind these, I'd trail either a small nymph or a small dry like a crippled emerger or a smaller ant pattern.  There are lots of different stimulator patterns that are working well at this time of day too, though keep them a little on the smaller side.  While several different colors are working, I recommend sticking to yellow, orange or olive.

     From late afternoon to the evening, you can switch to smaller dry flies.  Purple Hazes are the most consistent pattern, but mahoganies, Adams, and even PMD/Trico patterns work well at this point too.  We're also starting to see more and more October Caddis, so have something big and orange ready at this time of day too.  If you stay out late, I'd also recommend switching back to streamers as you approach dusk, because that can sometimes draw out some of the bigger fish.

     However you approach it, there is good fishing to be had on Rock Creek, so come on up!  More soon.

     The dry fly fishing has improved greatly over the past week, with hopper/ant/beetle patterns doing well in the middle of the day and with Adams/Haze/Mahogany patterns working in the late afternoons and into the evenings.  There are times when fish are short-striking and nosing some of these dries.  If that happens, put on a trailer about a foot behind these bugs.  Try a beadhead nymph behind the terrestrials and a crippled emerger behind the smaller dries.

     Streamers are probably the best sub-surface option right now, with black or olive streamers being especially good.  Here's a picture of a nice brownie our friend Joe caught on a black wooly bugger:

     Besides streamers, you can also use nymph patterns like girdle bugs or prince nymphs.  In the mornings in particular, try a double nymph tandem for the best results.  It's shaping up into a good September for fishing on Rock Creek!

September 4

     We are definitely moving into fall fishing now.  The mornings are much chillier than even two week ago, and the daylight is noticeably shortened.  The plus side to this is that the water temperatures are cooler now, and the fish are much more active (and this will only continue as we move into the month).

     I've already received a couple of reports of Mahogany Duns flying in the late afternoons / early evenings, and this will be the big dry fly hatch until the October caddis emerge.  In the meantime, try small mayfly patterns, Purple Hazes, and Parachute Adams.  Going under the surface is the best bet for consistent fishing, with girdle bugs, orange Serendipities, and black streamers being especially good right now.

     Overall, things are picking up for our fall fishing season, and there is still relatively little traffic out here, so finding an open fishing hole should be easy, especially in the middle to upper stretches of Rock Creek.
