Blue Lakes in Costilla County: How and When to Fish It

• Overview

  In Colorado, Blue Lakes belongs to Costilla County. The setting is mixed forest on every side. The water measures roughly 3 acres, so nothing here is far from anything else. It is high ground by Colorado standards. Alamosa East is the closest place, 20 miles off. Then Alamosa, 21 miles, and Monte Vista, 35 miles. No border sits close enough to matter.

• Where to Fish on Blue Lakes

  No published figure covers depth, so learn it as you fish. On a natural lake the weed line and the shelf beyond it do the work. This is a lake, so the margins and the first drop matter most. Fish documented in Costilla County include cutthroat trout, white sucker, black-spotted cutthroat trout, brook trout and yellow perch. County records show what lives in the area; the local agency holds the water-by-water list. Blue Lakes responds to conditions more than to tactics.

• Seasonal Patterns

  The range across the year is 19°F to 60°F. Winter puts a hard lid on this one. Ice is part of the season here, ending near late April. Open water usually runs from late April until about late November. May into June fishes hardest, and September gives a second good stretch before the lid returns. Blue Lakes runs to that rhythm year in and year out.

• Tackle & Baits

  Access is not recorded for this water. Nothing is mapped in the way of a ramp or car park within a short radius. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Where the road in crosses private land, ask first. Check whether bait restrictions apply before you buy any. Pioneer Lake sits 0.5 miles off and takes the overflow. Nothing here settles the position at Blue Lakes for certain.
