DSC_0653

気温もグッと下がって寒くなって来ました。ちょうど管理釣り場のトラウトには適水温になっているであろう、この季節。

行って来ました。京都府南部にある、ボートでトラウトが釣れる管理釣り場『通天湖』へ。

この時期、いつも大放流をされるのでホームページをチェックしてみると金曜日が放流、で自分の休みが土曜日!

これは行きたい!しかし、土曜日は子供に左右されるのが常々。とりあえず、お姉チャンに予定を聞いてみた。

「釣り行きたい。」

なんと、親父の思いを知ってか知らずか最高の返答が!ありがとう、ありがとう、どうぶつの森。

ということで向かった通天湖。道中は前日に降った雪で積雪もあり、釣り場も雪景色。

DSC_0641

昼前からスタート。とりあえずキャストを教えるところから始まり、重めのスプーンで広く探りますがマスさんは口を使ってくれません。

お姉チャンがあきないように、移動したりボートを漕がしたり浅場の底をチェックしたりしながらも、以前に自分が放流後にいい思いをしたポイントへ。

これが大正解。1投目からフェザージグにレインボーが、2投目クランクにも。

DSC_0644

さらに1.6gスプーンにも釣れてきて、どうも中層で浮いている感じ。

IMG_20171209_180220_456

お姉チャンもテンション上がって投げるも、木に引っかかったりで、なかなか掛からず。

しかし、ホスト役に徹してコチラが巻いて止めてを教えると早々にヒット!

IMG_20171212_195140_218

その後も掛かる→ばらすを何回か繰り返し、充分楽しんで時間となりました。

結果、お姉チャンも釣れて自分も満足した釣果に良い釣りができました。

「良かったなぁ釣れて。また付いて行ってあげるわ」

と帰りの車で、お褒めの言葉を頂きました。
