With daytime air temperatures 10 degrees below average and dreary skies over the past week, the river has been slow to warm. Yesterday's water temperature was 40 degrees and with trout having an optimal water temperature of around 54 degrees, their activity level is low. The Cold River is in deed cold! Until water temperature gets into the upper 40's, catching trout will be difficult. The best chances are focusing on deep pools and and slow runs. The water level is just a little above perfect right now and with the weather forecast calling for sunnier, warmer weather Wednesday through Sunday, the river could fish better by May 1st. May flies are in smaller instar stages right now, so nymphs in size 16-20 are best right now. Stone Fly nymphs in size 12-14 are a good choice. As far as hatches, all that was seen were a few random small caddis.
